Pentair, Inc
The GWI research shows that the Americas
accounted for the largest market share
until 2008. Since then, the Asia Pacific and
EMEA (Europe, Middle East and Africa)
markets each outgrew the Americas mainly due to strong growth in the market
for desalination pre-treatment and the
continuing strength of the wastewater
treatment sector. This has changed the
competitive dynamics of the sector, much
of it in favor of Pentair X-Flow.
As we work to combine our businesses in the coming months, our top priority is ensuring we
continue to serve you well and deliver on our commitments. If you have questions for us
regarding the acquisition or are interested in any of the solutions presented in this edition of
KnowHow, please don’t hesitate to contact one of our Pentair colleagues around the world.
Best regards,
The first is crucial in order to have direct
experience in key application segments
that feed the company’s R&D agenda and
integrates our vast knowledge base.
Pentair X-Flow then uses this know-how
to support our worldwide EPC contractors with state-of-the-art membrane
technology and application expertise.
Two key elements are believed to be at
the basis of this market success: First,
Pentair X-Flow has launched several
unique solutions into high growth market
segments including:
The acquisition enables Pentair Filtration Solutions to build on superior technology, increase
global capability and thereby provide you, our customers, with a broader, more innovative and
deeper array of products, services and solutions. In short, the combination helps create a true
global filtration, separation and fluid technology leader.

technology challenges.
solution during the late 1990s and early
2000s, reflecting growing interest in water
reuse, and the smaller plant footprints
offered by the membrane bioreactor format. The third stage of market development came in the mid-2000s when the
potential for low-pressure membranes as
a seawater pre-treatment method for
reverse osmosis was realized.
Though low-pressure MF and UF membranes have been available
for 80 years, it has only been in the last 20 years that they have
made serious inroads into the market. GWI’s conclusion is that
today, by some measures, the technology has overtaken reverse
osmosis in terms of popularity. The MF/UF market developed in
three key stages. The first stage was the spread of MF and UF for
drinking water treatment in the US following the 1993
Cryptosporidium outbreak in Milwaukee. The next stage was the
emergence of low-pressure membranes as a wastewater treatment
SEAGUARD, the industry’s first
dedicated seawater pre-treatment membrane module
Pentair Airlift™ MBR Megablock, a
direct sludge filtration system that represents the most cost, space and quality effective solution to meet stringent wastewater treatment directives and produce effluent with a quality suited for water reuse applications.
Secondly, Pentair X-Flow maintains a dual
market strategy of both directly executing
projects, primarily in Western Europe, and
being a premier membrane technology
and service supplier to a network of
design engineers and engineering, procurement and construction (EPC) contractors on the other hand.
Just prior to completing the acquisition of Norit CPT businesses by Pentair,
Norit was awarded the “Water

Protection at the tap
Ultrafiltration is an effective barrier for microbials
Frank van Heusden
What’s in your water?
Water is used from kitchen and bathroom taps
every day, but is the water really as safe, healthy
and great tasting as it could be? Unless the water
is filtered immediately before use with an
advanced technology like ultrafiltration (UF)
membranes there is no way to know for sure.
Rik Schuurman
The private German
brewery Ustersbach chose PENTAIR
Process Technology’s turnkey Beer
Membrane Filtration (BMF) installation
to upgrade the brewery’s beer filtration system.
Whether a home is on city or well water, harmful
or undesirable contaminants could be flowing
from faucets every day that you cannot see or
taste. Unfortunately, throughout the world even
with stringent national and local regulations, and
due diligence by water utilities, microbiological
contamination in water supplies is a reality. Old
and deteriorating water pipes and city water
main breaks can contaminate water before it
reaches a home. Private wells can become
contaminated at any time. Without constant
self-monitoring of a well, there is no way to
know when this happens. Due to the increased
publicity consumers worldwide realize the need
to be more vigilant about the quality of water
they are consuming.
Pentair Process Technology will install a turnkey stateof-the-art beer filtration installation that includes one
BMF-18 skid with a possible second BMF skid in the
future. The brewery is integrating the expansion
into the existing filter room. The completion of the
project is scheduled for fall 2011.
The Water Quality Association’s leadership is
working to encourage U.S. officials to understand
that the most practical solution to water related
issues is to integrate point-of-use (POU) into the
current regulatory paradigm. “Our goal is to
advance the understanding of policy makers
about final barrier treatment of drinking,” said
Peter Censky, executive director of WQA. “We
begin with a premise that within 20 years the
current paradigm – centrally treating water and
doing essentially nothing more – will no longer
work. Central treatment will not be able to cope
with the demand for higher quality water.”
Certified purification you can rely on
Pentair’s H2OK WaterPurifiers, which use Pentair
X-Flow UF membrane technology, are one of the
few POU drinking water products available in the
world certified by the Water Quality Association
(WQA) to retain 99.99 percent of viruses and cysts
and 99.9999 percent of bacteria. They carry the
WQA Gold Seal certification to both the US EPA
Standard for Microbiological Water Purifiers and
NSF P231.
Started in 1605 as a family business, Ustersbach is now
a renowned brewery with a diverse product line. The
brewery produces nine different beers including pilsner, pale beer, wheat beer, and strong beer, along
with a selection of soft drinks. All beers use mainly
local products, without pasteurization and in the
tradition relating to crafts following the Bavarian
purity requirement of 1516.
“Ultrafiltration membranes are hollow fiber
straw-like structures with walls that consist of
billions of microscopic pores that are smaller
than viruses, bacteria, protozoa, and fungi,” said
Anton van de Ven, Commercial Director at Pentair
Filtrix. “They are the ideal barrier for microbiological outbreaks, which is why they were chosen
for use in our WaterPurifiers.”
Pentair H2OK WaterPurifiers work on normal line
pressure, use no energy, do not generate any
wastewater in the filtering process, retain vital
minerals, and do not alter the taste of the water.
Membrane filters will block microbes up to the
expiration date making sure no contamination
can ever come through.

“The diatomaceous earth-free beer filtration is
gaining ground in the beer industry and we are
convinced that Pentair’s BMF system is in line
with our ambition to produce beer of the highest quality according to our family recipes while
using modern, efficient and environmentfriendly techniques,” said Stephanie Schmid,
owner of brewery Ustersbach.
Dick Meijer, Pentair Process Technology’s
Commercial Director - Beverage, added, “This
illustrates our capacity to prepare breweries of all sizes for
the future. Our BMF installation’s design enables breweries
to do more with less while focusing on the key elements of the

Double Duty
Guinness Anchor Berhad: Retrofitting with LiquiVap
increases CO2 recovery yield and lowers costs
Roy Spee
Approximately 60 percent of the costs associated with carbon
dioxide (CO2) recovery are attributable to the cooling stage of the process.
If less energy is required for cooling, it translates to a reduction in running
costs. This is precisely what the LiquiVap system from PENTAIR Haffmans
offers. For CO2 recovery systems undergoing expansion or retrofitting,
recovery yield can be improved for older systems. The Sungei Way Brewery
owned by Guinness Anchor Berhad in Malaysia is a representative case as this
brewery had two existing systems simultaneously retrofitted with LiquiVap.
Guinness Anchor Berhad (GAB) was founded in
1964 originally under the name “Guinness
Malaysia Limited”. In 1966, the company changed
its name to “Guinness Malaysia Berhad”, and in
1989, the name was again changed to GAB that
it operates under today. GAB is the product of a
fusion between Guinness Malaysia Berhad and
Malayan Breweries (Malaya) Sdn Bhd (“MBM”),
each of which are subsidiaries of Guinness
Overseas Ltd and Malayan Breweries Ltd, respectively. The latter operates under the name Asia
Pacific Breweries Limited (“APB”), based in
“We have not had
to purchase any
more CO2 and are
operating more
sustainably, as
we now use less
Chuah Chong Sheng, project engineer at
GAB and responsible for the CO2 supply,
is completely satisfied with the results
of retrofitting with the LiquiVap.
GAB operates the Sungei Way Brewery in
Malaysia, which was commissioned in 1965. The
brewery is located in the city of Petaling Jaya in
the state of Selangor, where it produces Tiger,
Guinness, Heineken, Anchor Smooth, Anchor
Strong, Kilkenny, Anglia Shandy, and Malta. The
plant’s capacity is approximately one million
hectoliter per year. GAB occupies the leading
position in the Malaysian beer market with a
market share of approximately 57 percent.
Either APB or Guinness
The Sungei Way Brewery is the only one of its
kind in the world. It consists of two production
lines, completely separate from one another, in
which only APB or only Guinness beers are
brewed. The maxim here is: The products are not
allowed to be mixed, not even the gases
liberated from fermentation. Consequently, the
brewery has two separate CO2 systems in operation that were both supplied by Pentair Haffmans
approximately 20 years ago.
Chuah Chong Sheng, project engineer for the
CO2 supply at GAB, shares his reflections on the
past. “We simply weren’t able to produce enough
of our own CO2 with the existing systems,” he
said. “Each month, we had to purchase supplemental CO2, which is complicated and expensive.
Also, the refrigerant R22 was still used in this
system, which is less than ideal from an environmental perspective.”
“We were immediately won over by this concept”
In order to find an optimal solution for this
problem, the brewery contacted Pentair Haffmans.
Initially, several completely different concepts
were developed and their respective advantages
evaluated. Replacement with a new plant would
have brought the highest efficiency, supplying
both brewing plants at a rate of 1,000 kg/h
simultaneously. However, this could not be
implemented at the time due to certain aspects of
the brewery’s strategic planning. Instead, the
decision was made to retrofit the existing
500 kg/h systems with the alternative presented
by the innovative unit known as the LiquiVap.
“This idea was very convincing, since the existing
plants were also manufactured by Pentair
Haffmans,” Chuah Chong Sheng recalled. “We
were already familiar with the products they are
capable of delivering and also the high level of
service from Pentair Haffmans. Furthermore, we
already have a LiquiVap unit at APB in Singapore,
providing us with a means for comparison. It has
been in operation there for more than a year.”
Evaporating CO2 cools fermentation gas
LiquiVap – a term created from abbreviations for
liquefaction and evaporation – is an energy saving
system for CO2 recovery plants. During recovery,
the gaseous CO2 must be cooled and liquefied
prior to storage in tanks at a temperature of -24
°C and a pressure of 18 bar. In order to be able to
utilize this stored liquid CO2 in the brewing process, the liquid CO2 is heated with air or steam and
This “energy of evaporation” can be captured
very efficiently from this process with the LiquiVap
system. As the CO2 evaporates, it liquefies the
gaseous carbon dioxide coming from the activated carbon filters and dryers. In this manner, the
energy is recovered that would otherwise be electrically fed into the refrigeration system.
Additionally, the cooling capacities required of
the refrigeration systems are significantly lower.
When undertaking the expansion of a CO2 recovery system’s overall capacity, one can forego a
complete expansion of the refrigeration system’s
capacity in favor of installing a LiquiVap unit.
If less energy is required for cooling, this directly
results in lower total costs associated with CO2.
Yet another advantage of the LiquiVap is that it
does not contain any mechanical parts, making
continuous operation possible over long periods
without interruptions for maintenance. Reducing
the hours of operation of an existing refrigeration
system as well as its maintenance costs are certainly not the least of these advantages, which
also include increased reliability.
Optimal energy efficiency all of the time
However, with LiquiVap the amount of cooling
that takes place directly corresponds to the
amount of evaporation. To integrate it into realworld applications, system operation is important. During the cooling stage to assure operations are within the most optimal range, the
cooling capacity needs to adjust to production
variables. For example, if the system is dimensioned for 500 kg/h but production only requires
400 kg/h, then only 400 kg/h can be cooled using
the LiquiVap. Separate cooling capacity is
required for the remaining 100 kg/h must be
cooled by the existing refrigeration system. But,
it is essential to understand that the control
system precisely regulates the refrigeration
process so that the energy required to cool the
100 kg/h is consumed – no more and no less. In
this manner, energy efficiency always remains at
an optimal level.
Four percent makes a difference
At the GAB Brewery, in addition to retrofitting
with a LiquiVap unit and the installation of the
latest control system, the entire final stage of
CO2 treatment was redesigned. The previously
employed means for cooling the CO2, in which
the less desirable refrigerant was used, was
replaced and modernized with one designed to
meet future environmental requirements. Using
the innovative LiquiVap system, very low process
temperatures are possible. As a result, gas at an
initial purity of 95 percent can be recovered,
compared to the situation before retrofitting, in
which it was only feasible with gas at an initial
purity of 99 percent. The difference of four percent means that the fermenters can be connected earlier, and, therefore, a greater volume of
CO2 can be recovered. “For over a year, both of
our plants have proven their value under the
challenging production conditions we experience on a daily basis,” Chuah Chong Sheng
explained in summarizing this successful project.
“Since commissioning these units, we have
indeed become self-sufficient and have not had
to purchase any CO2 – not to mention that we
have achieved this in conjunction with savings
through utilizing sustainable energy as well. We
are completely satisfied with all aspects of retrofitting with the LiquiVap.”
The recovered CO2
(green line) is liquefied in the LiquiVap
unit through the
evaporation of liquid
CO2 (blue line) –
energy savings in
both the cooling and
heating stages of the
process are the result.

XIGA™ - the membrane of choice around the globe
Swedish water treatment plant to utilize XIGA
A three-phase project in Gothenburg, Sweden to
increase production capabilities of purifying surface water to drinking water will use Pentair
X-Flow’s ultrafiltration (UF) technology.
Gothenburg, the second largest city in the country, is located on the west coast of Sweden. The
city’s water treatment facility must supply approximately 500,000 consumers with drinking water
using surface water and river water from the Göta
älv (Gota River).
The three phases of the project will increase
water production to meet demand and high quality standards. Phase one will produce 1,800 m3/h
by 2013, Phase two, 3,600 m3/h in 2015, and Phase
three, 7,000 m3/h in 2017. In the first phase of the
project, a UF plant with four Pentair X-Flow skids,
each equipped with 36 pressure vessels containing
XIGA UF membranes, will be installed in an existing water production plant. By the end of Phase
three, 16 skids will be installed. Pentair X-Flow has
partnered with Purac, a prestigious Swedish contracting firm, for this project.
In the treatment process surface water is coagulated and, after settling, sent through granular
activated carbon filters. The output of the carbon
filters is transferred through the UF membrane
The membranes remove all fine silt
and turbidity (suspended particles)
and create a hygienic barrier for bacteria, viruses
and other microorganisms. The XIGA configuration consists of multiple membranes installed in
horizontal pressure housings. These membranes
produce the highest quality water.
XIGA to be used in Singapore drinking water project
Pentair Water Asia Pacific will supply Pentair
X-Flow’s XIGA ultrafiltration (UF) membranes to
the Lower Seletar Waterworks project in
Singapore to be constructed by Sembawang
Engineers and Constructors (Sembawang), one of
the leading engineering and construction companies in Southeast Asia.
Once constructed, with a capacity to process 300 MLD
of raw water into drinking water, the Lower Seletar
Waterworks will be one of the largest drinking water
plants in Singapore that utilizes UF at the front of its
treatment process. It is also the first drinking water
plant in Singapore to use a pressurized UF membrane
Pentair X-Flow XIGA UF membranes are widely used
throughout the world for large-scale drinking water
production and effluent reuse. They are horizontally
mounted membranes housed in pressure vessels.
The pressure vessels are stacked on a skid to reduce the
footprint, which makes Pentair X-Flow’s XIGA UF membrane system well suited for the Lower Seletar plant’s
limited footprint. In addition, the absolute pore size of
XIGA membranes ranges from 0.025 to 0.030 microns
making XIGA one of the tightest in its class. This enables
high log removal for both bacteria and viruses.
Singapore is a land-scarce country
with limited water resources. As such,
the nation has long recognized the importance of
developing and maximizing its water resources to
sustain its economic growth and modern lifestyle
of its citizens. PUB, the nation’s water authority,
has initiated many internationally renowned projects including NEWater factories, the Tuas desalination plant and the Marina Barrage (for urban
water collection). With its aim of becoming one of
the world’s hydro hubs, Singapore always welcomes and embraces the use of advanced water
purification technology in its quest to increase the
nation’s water supply and improve its water security. The selection of Pentair X-Flow’s XIGA UF
membranes for drinking water production at the
Lower Seletar plant bears further testament to
the high quality and reliability of Pentair X-Flow
membrane products.
Abu Dhabian wastewater polishing plant to be equipped with XIGA
Pentair X-Flow supplies XIGA membranes to the
engineering firm Boustead Salcon Water Solutions
for wastewater treatment for reuse at the Abu
Dhabi Sewerage Services Company’s (ADSSC) Al
Wathba Enhanced Treated Sewage Effluent (TSE)
Treatment Project. The new wastewater recycling
plant is the first of its kind in the United Arab
Emirates (UAE) and has a capacity of approximately 27,712 m3 (6 million gallons) per day.
The UAE depends on desalination to
supply water. By focusing on wastewater reuse, the UAE is responding to the need to
ensure security for its long-term water supply. In
2010, Abu Dhabi introduced new wastewater
regulations, and by doing so the Emirate established itself as the regional leader in the water
reuse sector.
In addition to the ultrafiltration (UF) polishing of
the TSE, the plant includes a strainer and ultraviolet protection processes. An estimated 95 percent of the TSE supplied to the plant will be
recycled and recovered. This water is used for
agricultural irrigation and horizontal landscaping.
The Al Wathba TSE polishing plant is important in
setting the trend in the UAE for wastewater treatment using UF membranes for tertiary filtration
of treated sewage. This technology provides a
credible and proven alternative to the desalination of seawater for non-potable applications. By
supplying UF technology to the ADSSC’s Al
Wathba plant, Pentair X-Flow reinforces its position as the UF market leader in the Middle East.
“The use of XIGA membranes for drinking water
production could potentially reduce the cost of
downstream disinfection and provide cost savings for
the end-user,” explained Duane Schlicht, Managing
Director Pentair Water Asia Pacific.

365 it Complete PMO
Mix Proof Valve
william craig
In July 2010, Beijing
Shiqiao Bio-Medicine Manufacturing Co., a Chinese pharmaceutical
producer, contracted PENTAIR
Südmo to design, build and validate a state-of-the-art amino acid
infusions workshop at its new
Green-field factory, currently
under construction on the outskirts of Beijing.
This is the first of at least seven workshops planned
for construction on the site. Beijing Shiqiao BioMedicine Manufacturing wants the first workshop
to set an example as providing the highest quality
production process available to manufacture premium amino acid infusion products that conform
to US FDA, China GMP and European Pharmacopeia
standards. This will help open the door for potential export opportunities.
Pentair Südmo was successful in winning the order
against stiff competition from both local and
international companies. The project includes the
design, delivery, building and validating of a fully
automatic, aseptic process system. A feature of the
system is Pentair Südmo’s latest generation of SVP
Single Seat valves with P3 diaphragm and PEEK
valve seal for superior performance during aseptic
processing. The full scope of the project includes
preparation vessels, transfer systems, powder addition and blending, activated carbon filtration,
sterile filtration, and clean-in-place (CIP) and
sterilization-in-place (SIP) systems. In addition,
Pentair Südmo is the overall general consultant for
the complete amino acid workshop construction
and will design, deliver and build all peripheral
utilities for both clean and non-clean applications.
These include water for injection and purified
water storage, and distribution circuits.
Dairy processors have a new way to look at mix
proof technology with Pentair Südmo’s 365it Complete PMO Valve. The
valve, approved according to the 3A standard 85-02 (FDA Memorandum
applied for) provides complete product protection at all times including
during seat lifting and even with seals missing. Operators can be assured
of maximum security when there is product and CIP in opposite lines.
reduces the valve’s weight and building space
requirement, and provides easier handling
and maintenance.
Joint European-Chinese Project team discussing technical details
Pentair Südmo enters
China’s pharma market
Delivery of this landmark project for Pentair Südmo will be through
a team effort between Pentair Südmo in Germany, Pentair Water
Purification Systems in Beijing and selected local partner companies.
“As with all projects, we strive to provide the most professional,
highest quality and leading technological service,” said Friedrich Elz,
Business Unit Manager Pharma-Dairy-Food at Pentair Südmo.
“Pentair Südmo is a well respected, global player in the pharmaceutical sector but provides a local presence and understanding. We are
dedicated to increasing the efficiency and performance of our customers’ operations in a most cost effective way.”
Pentair Südmo’s patented deflector technology upgrades a standard DSV Complete Valve
to the 365it Complete. The deflector guides
CIP fluid directly into the leakage outlet
during seat lifting and creates a vacuum just
in front of the opposite side seal thus avoiding direct impingement of the opposite seal.
Smaller lighter leaner
Pentair Südmo engineers are constantly looking for ways that help our customers ‘do
more with less’. The most recent technological breakthrough, the 365it Complete, based
on the DSV Complete Valve, uses a standard
housing without increasing the size of the
leakage outlet port. Up to now, this was
necessary to avoid pressure build up in the
leakage area. The addition of this advantage
With the 365it Complete Valve and the reduced
size of the leakage port, dairy plants will experience OPEX savings due to less cleaning media
loss during seat lifting while maintaining maximum product safety. During daily operations,
the new radial seal compensates for swelling,
which reduces wear and provides an extremely
robust and long life resulting in even greater
life cycle cost savings.
In 2010 the 3-A document adopted terminology from
the Pasteurized Milk Ordinance (PMO), which means
that with 3-A approval double seat/mix proof valves,
including Pentair Südmo’s 365it Complete Mix Proof
Valve, now meet the PMO guidelines. This means that
the valve can be used in U.S. dairy plants.
The design phase for this project is well underway and on-site
activities are set to begin in the spring of 2011.
Containerized pump rooms for
projects in Romania and Venezuela
Inge Sluijter
Pentair Nijhuis
supplied the engineering, procurement and construction contractor (EPCC) Ferrostaal with complete containerized firefighting
pump rooms for projects in Romania
and Venezuela. The compact and
tested modular design of the pump
rooms provides a very efficient
solution. Such a complete supply
considerably reduces the risk of
assembly errors and saves construction time on site. Ferrostaal,
an organization with 60 offices
worldwide, recognized these
important ad-vantages.

compressed gas to the national gas network.”
Firefighting pump room protects
gas and oil plant
“One pump room was installed for the end customer OMV Petrom S.A. at its new gas compressor station in Bulbuceni, Romania,” said Niels
van den Hurk, Pentair Nijhuis’ area sales manager. “Petrom is the largest corporation in
The pump room in Bulbuceni needed to meet Petrom’s
safety requirements and strict sound reduction
demands to protect personnel and the work area.
Since the equipment is tested weekly, part of
meeting these guidelines included insulating the
pump room so that the sound level from one meter
measures less than 85 dBA.
In addition to the customer’s requirements, a number of extreme conditions that are decisive factors
for selecting the proper diesel engine were taken
into account for the pump room design. These
conditions are: the site is located at 208 meters
(682 feet) above sea level, the surroundings temperature varies between minus 29 and 40 degrees
Celsius (minus 20 and 104 degrees Fahrenheit) and
the average relative humidity is 63 percent. The
pump room, consisting of four pumps and two
jockey pumps –that serve to maintain water pres-
sure in the sprinkler system–, provides the complete water supply for fire protection at this location.
“The pump room was designed according to the latest directives of the National Fire Protection
Association’s (NFPA) international standard NFPA20,” van den Hurk said. “Besides that I am proud to
say that we were able to meet all extra requirements, even though the conditions were challenging.”
New power plant in Venezuela protected against fire
The end customer of the second pump room, C.A.
Energía Eléctrica de Venezuela (Enelven), built two
combined cycle power plants in Zulia state, Venezuela.
These power plants will supply sufficient energy to
meet the energy demand of the entire region.
“The EPCC of this project, Ferrostaal, initially contacted Pentair Nijhuis to supply separate firefighting
pumps at the location in Bachaquero,” van den Hurk
said. “But, considering the remote location, they
chose the containerized pump room option, and thus
profit from the advantages of this solution.”
The pump room contains two firefighting pumps, one
diesel driven, one electric driven pump, and one
jockey pump. All pumps comply with the latest regulations of NFPA-20, and are Factory Mutual (FM)
approved. In addition, extra devices, supplied by the
customer, were successfully incorporated into the total
containerized concept.
“Constructing containerized units requires expertise
that is available within Pentair Nijhuis,” van den Hurk
said. “The firefighting equipment at both Petrom and
Enelven well prepares both locations in the event of a
fire. Studies have shown that when such units are in
place, fire damage will be restricted to less than
10 percent, thus providing lower costs and less environmental impact.”

“This a great step for Pentair Haffmans and
fits perfectly into the shift towards renewable
energy sources,” said Olaf Müller, Managing
Director Pentair Haffmans, Head of Beverage
and Niche Markets - Pentair Clean Process
Technologies. “The energy targets of the
European Union state that in 2020 20 percent
of the energy used should come from alternative energy sources.”

Inge Sluijter The social responsibility of organizations is the center of attention now more than
ever. To provide guidance for corporations the
International Organization for Standardization
(ISO) has worked for five years to establish a directive on the implementation of social responsibility
(SR). In 2010, an international consensus was
reached on the International Standard ISO
26000:2010, Guidance on social responsibility.
Following that, the Dutch Standardization Institute (NEN) introduced its version of the directive
on December 9, 2010.
ISO 26000 is a guidance standard and is
not for certification. It offers structure
to organizations for implementing SR.
The directive concerns SR core subjects
including organizational governance,
environment, fair operating practices,
community involvement, human rights,
labor issues, and consumer/customer
“NEN is soon publishing a book with
practical experiences of ISO 26000
champions, and Pentair Nijhuis is one
of them,” Schuuring added. “Together
with nine other companies, we were
the first Dutch company to implement
this directive. Our successes and learning points will help other companies
with their corporate social responsibility challenge.”
In February, the biogas upgrading installation
in Witteveen, the Netherlands exceeded the milestone of producing and feeding 250,000 Nm3
biomethane into the gas grid. This is enough to
foresee some 160 households with their annual
This biogas upgrading plant is the first of its kind. Pentair
Haffmans installed the plant at Bouwhuis Biovergisting BV in
Witteveen in November 2010. Bouwhuis is an agricultural company that produces biogas from corn.
The company expanded the capacity of its two running combined
heat and power (CHP) installations. The additional 350 Nm3/h
biogas are upgraded by Pentair Haffmans into 215 Nm3/h biomethane and 250 kg/h purified carbon dioxide (CO2).
Biogas is a general term for gas produced
through an anaerobic fermentation process
and primarily consists of a mixture of methane
(CH4) and CO2. The upgrading technology
recovers 100 percent of the CH4 and causes no
CH4 losses. In the process the biogas is first
cleaned by a Norit activated carbon filter and
then the cleaned biogas flows through a membrane installation and a CO2 recovery system.
The biomethane produced by the upgrading
system has the same specifications as natural
gas and has been accepted by Enexis for injecting it into the national gas grid. Enexis is
responsible for the development, construction, maintenance and management of the
gas and energy distribution network. As such
the company is the link between 2.6 million
customers and the energy suppliers.
The recovered CO2 has a high purity and can
be used as CO2 gas in greenhouses or liquefied
and stored for use in the food and beverage
Pentair Nijhuis is member of a pilot group of organizations that have
started the implementation of this NEN directive. During the introduction seminar on December 9, practical experiences with the application of ISO 26000 in business and industry were presented. Pentair
Nijhuis’ Managing Director Robert Schuuring was one of the speakers.
“ISO 26000 is well suited to Pentair Nijhuis,” he said. “Our products
represent quality, high efficiency and durability. We use ISO 26000 as
a guide to integrate social responsibility into our values and practices.
We are taking an even more critical look at our purchase and production processes and the social environment. ISO 26000 presents a very
good approach in doing so.”

Pentair X-Flow wins 2011
iF Product Design Award
Pentair X-Flow’s Airlift™ MBR Megablock, was honored
by the International Forum Design (iF) for excellence in
product design. In total, 2,756 products from 1,121 participants competed for this prestigious design award.
Winning the award confirms that pentair X-Flow’s
expertise in combining state-of-art technology with
appealing design features.
The iF Product Design Awards are prestigious awards that recognize manufacturers and designers of industrial products exhibiting superior design from around the world in a variety of
categories. Selection criteria include the quality of design, functionality, degree of innovation, simplicity of operation, and
environmental impact. The Pentair Megablock is used in municipal wastewater treatment.
Prompt action by the Pentair Nijhuis
service team prevented a major disruption at the Dolfinarium, a dolphin
theme park in Münster, Germany. Two
pump rooms at the facility were flooded due to a water pipe leak. The leak
was repaired and the pump rooms
were drained, but the pumps needed
to be repaired and restarted to maintain the water in the pool where the
dolphins and other sea animals live.
This had to be done quickly to avoid
the need to move the animals 300 km
to the Dolfinarium in Harderwijk, the
Netherlands. Thanks to Pentair Nijhuis’
experienced service team the pumps
were started up in time and the move
was not necessary. A well earned
“thank you” was the result.
Specifically it is the sludge separating component of large-scale Membrane
BioReactor (MBR) systems. The compact membrane separation system within
the Megablock produces crystal-clear, bacteria-free water from a biological
wastewater treatment process that can be reused for a variety of purposes.
In addition, the membranes are in a dry and clean environment making
them quickly accessible without comprising the health and safety of plant
iF praised the Megablock for its “Lego™-Style” modular design that allows
for easy installation and system expansion. Its advanced component design
improves fluid flow and aeration, resulting in unprecedented performance.
“The Efficient Performance Technology philosophy - our guiding principle in
product development - led to the Megablock’s development,” said Rick
Rosberg, Global Commercial Director of Pentair X-Flow. “A compact, modular design flows naturally from our ambition to do more with less.”
