pOsItIOn and the GrOWth Of uf and mf teChnOLOGy.
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
solution during the late 1990s and early
2000s, reflecting growing interest in water
reuse, and the smaller plant footprints
offered by the membrane bioreactor for-
mat. The third stage of market develop-
ment came in the mid-2000s when the
potential for low-pressure membranes as
a seawater pre-treatment method for
reverse osmosis was realized.
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 main-
ly 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.
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:
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, pro-
curement and construction (EPC) contrac-
tors on the other hand.
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 contrac-
tors with state-of-the-art membrane
technology and application expertise.

ultrafiltration is an effective barrier for microbialsprotection at the tap
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.
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.
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.
“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 microbio-
logical 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.
Clean, safe and easy
The easiest and most economical way to ensure
safe drinking water is to filter it at the tap. When
choosing an in-home water treatment system, it
is important to know that all POU filtration
products are not the same. To ensure the safest,
highest quality water possible, you should choose
a filter that is certified to protect against viruses,
cysts and bacteria, and removes chemical
contaminants while delivering great-tasting,
odor-free water The Pentair WaterPurifier+ that
combines UF membranes and activated carbon
provides this complete protection.
“Pentair H2OK WaterPurifiers are well positioned
against other POU technologies on the market,”
van de Ven said. “Overall, UF is an excellent and
sustainable way to eliminate the uncertainty of
microbiological outbreaks and ensure consistent
delivery of high-quality water, without electricity
or wasted water that other technologies require.”

Pentair Process Technology will install a turnkey state-
of-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.
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 pils-
ner, 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.
“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 high-
est quality according to our family recipes while
using modern, efficient and environment-
friendly techniques,” said Stephanie Schmid,
owner of brewery Ustersbach.
Dick Meijer, Pentair Process Technology’s
Commercial Director - Beverage, added, “This
illustrates our capacity to pre-
pare breweries of all sizes for
the future. Our BMF installa-
tion’s design enables breweries
to do more with less while focus-
ing on the key elements of the
century-old beer tradition of
quality, innovation, care for the
environment, and sustainabili-
ty.”

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, respec-tively. The latter operates under the name Asia Pacific Breweries Limited (“APB”), based in Singapore.
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 GuinnessThe 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 opera-tion 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 supple-mental CO2, which is complicated and expensive. Also, the refrigerant R22 was still used in this system, which is less than ideal from an environ-mental 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.
double duty Guinness Anchor berhad: Retrofitting with liquivap increases Co2 recovery yield and lowers costs
“We have not had to purchase any more CO2 and are operating more sustainably, as we now use less electricity.”
Chuah Chong sheng, project engineer at GAb and responsible for the Co2 supply, is completely satisfied with the results of retrofitting with the liquivap.
7K n o w H o w i 2 0 1 1 i 1
“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 gasLiquiVap – 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 pro-cess, the liquid CO2 is heated with air or steam and evaporated.
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 activat-ed carbon filters and dryers. In this manner, the energy is recovered that would otherwise be elec-trically fed into the refrigeration system. Additionally, the cooling capacities required of the refrigeration systems are significantly lower. When undertaking the expansion of a CO2 recov-ery 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 cer-tainly not the least of these advantages, which also include increased reliability.
optimal energy efficiency all of the timeHowever, with LiquiVap the amount of cooling that takes place directly corresponds to the amount of evaporation. To integrate it into real-world applications, system operation is impor-tant. During the cooling stage to assure opera-tions are within the most optimal range, the cooling capacity needs to adjust to production variables. For example, if the system is dimen-sioned 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 differenceAt the GAB Brewery, in addition to retrofitting
double duty 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 per-cent means that the fermenters can be connect-ed 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 experi-ence 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 retro-fitting with the LiquiVap.”
The recovered CO2 (green line) is lique-fied 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.

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 compa-
nies 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
system.
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 mem-
brane 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.
“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.
XIGA™ - the membrane of choice around the globe
A three-phase project in Gothenburg, Sweden to
increase production capabilities of purifying sur-
face water to drinking water will use Pentair
X-Flow’s ultrafiltration (UF) technology.
Gothenburg, the second largest city in the coun-
try, is located on the west coast of Sweden. The
city’s water treatment facility must supply approx-
imately 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 qual-
ity 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 exist-
ing water production plant. By the end of Phase
three, 16 skids will be installed. Pentair X-Flow has
partnered with Purac, a prestigious Swedish con-
tracting firm, for this project.
In the treatment process surface water is coagu-
lated and, after settling, sent through granular
activated carbon filters. The output of the carbon
filters is transferred through the UF membrane
system.

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 proj-
ects including NEWater factories, the Tuas desali-
nation plant and the Marina Barrage (for urban
water collection). With its aim of becoming one of
the world’s hydro hubs, Singapore always wel-
comes and embraces the use of advanced water
purification technology in its quest to increase the
nation’s water supply and improve its water secu-
rity. 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.
The UAE depends on desalination to
supply water. By focusing on waste-
water 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 estab-
lished 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 ultra-
violet protection processes. An estimated 95 per-
cent of the TSE supplied to the plant will be
recycled and recovered. This water is used for
agricultural irrigation and horizontal land-
scaping.
The Al Wathba TSE polishing plant is important in
setting the trend in the UAE for wastewater treat-
ment using UF membranes for tertiary filtration
of treated sewage. This technology provides a
credible and proven alternative to the desalina-
tion of seawater for non-potable applications. By
supplying UF technology to the ADSSC’s Al
Wathba plant, Pentair X-Flow reinforces its posi-
tion as the UF market leader in the Middle East.

Pentair Südmo engineers are constantly look-
ing for ways that help our customers ‘do
more with less’. The most recent technologi-
cal 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
reduces the valve’s weight and building space
requirement, and provides easier handling
and maintenance.
Pentair Südmo’s patented deflector techno-
logy 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 avoid-
ing direct impingement of the opposite seal.
With the 365it Complete Valve and the
reduced size of the leakage port, dairy plants
will experience OPEX savings due to less clean-
ing media loss during seat lifting while main-
taining 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.

Firefighting pump room protects
gas and oil plant
“One pump room was installed for the end cus-
tomer OMV Petrom S.A. at its new gas compres-
sor station in Bulbuceni, Romania,” said Niels
van den Hurk, Pentair Nijhuis’ area sales mana-
ger. “Petrom is the largest corporation in
Romania and the largest gas and oil producer in
Eastern Europe. From Bulbuceni, Petrom provides
compressed gas to the national gas network.”
The pump room in Bulbuceni needed to meet
Petrom’s safety requirements and strict sound reduc-
tion 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 num-
ber 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 tem-
perature 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 com-
plete water supply for fire protection at this loca-
tion.
“The pump room was designed according to the lat-
est directives of the National Fire Protection
Association’s (NFPA) international standard NFPA-
20,” van den Hurk said. “Besides that I am proud to
say that we were able to meet all extra require-
ments, even though the conditions were challeng-
ing.”
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 contact-
ed 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 regula-
tions 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 envi-
ronmental impact.”

Pentair Nijhuis is member of a pilot group of organizations that have
started the implementation of this NEN directive. During the intro-
duction seminar on December 9, practical experiences with the appli-
cation 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 produc-
tion processes and the social environment. ISO 26000 presents a very
good approach in doing so.”
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
issues.
“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 learn-
ing points will help other companies
with their corporate social responsibil-
ity challenge.”

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 com-
pany 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 bio-
methane and 250 kg/h purified carbon dioxide (CO2).
“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 alterna-
tive energy sources.”
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 mem-
brane 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 inject-
ing it into the national gas grid. Enexis is
responsible for the development, construc-
tion, 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
industries.
biogas upgrading installation reaches first milestone!

The iF Product Design Awards are prestigious awards that recog-
nize manufacturers and designers of industrial products exhibit-
ing superior design from around the world in a variety of
categories. Selection criteria include the quality of design, func-
tionality, degree of innovation, simplicity of operation, and
environmental impact. The Pentair Megablock is used in muni-
cipal wastewater treatment.
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
workers.
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, modu-
lar design flows naturally from our ambition to do more with less.”
Prompt action by the Pentair Nijhuis
service team prevented a major disrup-
tion at the Dolfinarium, a dolphin
theme park in Münster, Germany. Two
pump rooms at the facility were flood-
ed 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 main-
tain 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.
