In the production process of electronic
components from condensers up to micro-
processors the purity of process liquids
is becoming more and more significant.
ultrafilter now offers innovative and
reliable products which comply with new
production standards while also guarantee
high production quality.
The special merits of the ultrafilter products are the following:
v economic processing
v short suspension/inaction and maintenance time
v minimum loss of raw materials
v maximum flow rates at low differential pressures
v low extractables
v minimum pre-rinse time
ultrafilter offers membranes with particle retention rates down to 0.04 µm depending
on the medium that you want to filter there is a wide range of elements and housings to
choose from.
The polypropylen-depthfilter which serve as a prefilter, have a high dirt hold capacity
and are the first link in the filtration chain. The last step is the membrane filtration with
retention rates of particles down to 0.04 micron.
ultrafilter in the electronic industry

Filtration of ultrapure water In the electronic industry the demand for de-ionised water of high purity is increasing.
In addition to the removal of particles there are more requirements that these filtration
systems must meet, e.g. short pre-rinse times after a filter change, a minimum migration
of extractables, as well a non disruption due to ion migration.
Furthermore, high flow rates and a low differential pressure are crucial parameters for a
cost effective filtration process.
The following picture shows the process in a RO-system schematically.
Prefilter In an RO-system the task of the prefilter
is to constantly supply the same water-
quality, independent from the changing
input parameters. This is particularly
important in order to protect the sensible
and expensive reverse osmosis mem-
branes.
Resin-catcher Frequently fine particles and dust are
washed out in the ion exchanger. This
leads to the blocking of the membrane
filters. That is why it makes sense and
is cost efficient to implement a depth
filter with an absolute retention rate and
a high dirt hold capacity behind the ion
exchanger.
Final filtrationDuring this final level before the point of
use a very fine filtration is necessary.
All particles and contamination up to a
size of 40 nanometers are held back by a
membrane filter, thereby guaranteeing
the best possible quality of the ultrapure
water and the manufactured products.

Circuit boardsThe present technique for producing circuit boards is the
so-called surface mount assembly. This technique requires
an extremely high purity and filtration quality of the process
liquids.
The following picture (pic. 2) shows a typical manufacturing
process. The de-ionised water and process liquids have
to be filtered while being cleaned. This must also be done in the course of
the different coating baths in order to ensure an optimal production process and to
minimize the amount of substandard products. Common contamination are metaloxides,
dust, undissolved salts and particles.

Compact disc, CD-ROM and DVDFor some years now Compact Discs have superseded and replaced records in the music
industry. In the computer industry the CD-ROM is the most widely used memory medium –
and its share in the market is still growing.
Filtration systems are also growing due to high quality requirements and standards
concerning storage density and capacity, the requirements for the materials used in the
production process.
A new generation of CD-ROMS with an even higher density the so called DVD-technique
(Digital Video Disc) continues this trend.
In order to avoid reading- and/or writing errors even the most insignificant contamination
and particles must be filtered out in all
process liquids and gases.
Picture 3 shows the manufacturing
process typical of a compact disc.
The following table lists those ultrafilter
products that are used in the
manufacturing of compact discs.
Every single product will be described in
detail in the following part of the catalog.

Hard disc drivesLike in the manufacturing of compact discs, increasing quality is also vital in
manufacturing of hard disc drives. The reasons for a consistantly better quality
of the input media are, as mentioned earlier, the result of a higher density of
memory as well as the development to reduce the indescribable gaps of the hard disc.
In the manufacturing process of hard discs great amounts of de-ionised water of highest
purity are needed. After the filtration the water must be free from interfering particles,
e.g. in form of silicates or smallest contmination of bacteriological size.
In the cleaning and preparation of the board for coating with nickel, the used process
liquids also have to be filtered in order to guarantee a consistantly high quality of
production and minimum product rejections.

Pic. 4: Hard disc production
ultrafilter offers a broad variety of filters
and housings for the production of hard
discs and the corresponding process
liquids (see pic. 4).
Independent from outer influences or
variations in the quality of the used liquids
a constant quality of the final product is
ensured.

ultrafilter in the beverage industry
Beside the optically clarification of the final product the food and beverage industry
emphasizes the removal of bacteria and micro-organisms.
Consumers do not want fibers, particles of undissolved ingredients in their drinks.
Substances that would alter the taste and influence the product’s characteristic features
are also undesireable. Bacteria and other micro-organisms reduce the shelf
life and may eventually also lead to a change in taste.
Apart from the filtration of liquids, large amounts of compressed air, carbon dioxide (CO2)
and nitrogen (N2) are also needed in the food and beverage industry.
Those have to be filtered too, in order to ensure a consistantly high quality within the
given products.
ultrafilter offers a broad variety of filters
for applications in the food and beverage
industry. Individually tailored for different
applications and requirements, it is
always economic efficiency in combination
with security and reliability that is most
important. Examples of typical ultrafilter
applications of elements in the food and
beverage industry will become evident on
the following pages.

Steam
A good steam quality is necessary for the sterilization of the filters and the tanks,
because it enhances the service life of the filters and more importantly it guarantees a
constant product quality.

Sterilization Saturated steam ultrex P-GS 1–25 µm 48
WaterWater is used for rinsing and cleaning of filling jets, bottles, kegs or other containers.
This water should be sterile, so that the rinsing does not result in contamination.
Water is also very often part of the final
process or even the final product itself.
Therefore one must recognize the im-
portance of the fine filtration of table-
or mineral waters, the sterile filtration
or bacteria reduction of water intended
for the addition to non-alcoholic drinks,
juices, beer or syrup.

Aeration and de-aeration To avoid the contamination of storage tanks or transportation containers for water, wine, juices, liquid sugar or other liquids by
bacteria, the use of sterile vent filters is necessary. ultrafilter offers a wide choice of filters for every size and type of tank as well as for
various filling and emptying rates.
Aeration and de-aeration filters are designed to work under atmosphaeric conditions. For this reason a low differential pressure and a
reverse flow direction are the most important parameters, apart from a long service life and a high dirt hold capacity.
The housing should offer an optimized flow rate and a splash protection to protect the filter medium from the liquid inside the tank.
All these characteristics are combined in the ultrafilter aeration and de-aeration filter ultradepth® P-BE.
Various types of elements offer an efficient protection of the stored products.

The filtration of wine should neither affect the taste nor the color of the wine.
ultrafilter offers depth and membrane filters for the filtration before filling and
cold stabilization after the D.E. filter.
This removes micro-organisms, bacteria and particles effectively without influencing the
“spirit of the wine”. A typical application in the filtration of wine is shown in picture 6.

BeerIn the production process of beer ultrafilter offers depth-
and membrane filters for the removal of particles, bacteria
and yeast. This process follows the Diatomaceous Earth
filtration (D.E. filter) before filling.
Not all breweries have sediment free water sources,
it is recommended, for these applications, to filter the
water in order to ensure a consistant input quality of the beer.

DairiesThe processing of milk in dairies can be described as follows:
In a first stage the milk is separated into creme and milk with a reduced fat content.
After this separation a thermal the milk is usually thermally treated (heated or chilled)
to reduce the amount of bacteria or prevent them from growing.
After this second stage the following process should take place under sterile conditions.

ultrafilter in thefood industry
Beside these products there are other so called sour milk products such as:
16
v Sterile storage of milk, milk product and additives
(e.g. fruit, water or flavors) only in sterile vented and bacteriophage
free tanks.
v Transportation of powder products only with sterile compressed air or
other sterile filtered gases.
v Purging of storage or holding tanks with a laminar flow of sterile air.
v Regular cleaning and sterilization with steam, sterile water
or chemicals.
v Aseptic filling and packaging of the final product under
a sterile atmosphere to prevent bacteria penetration.
Sterile means that equipment such as, storage or holding tanks, mixer, etc.
which comes into direct contact with the actual product do not cause any
bacteriological contamination.
The advantages of these sterile conditions are mainly:
v Best possible and consistent quality
v Extended shelf life of the product
v Reduction or exclusion of preservatives
v Protection from fermentation bacteria’s and no foreign growth
Sterile conditions improve the market potential of dairies because
a longer shelf life could allow them to develop new markets, reduce the
loss of products due to foreign growth in the fermentation process,
and improve of the manufacturing process ensuring consistent quality of
the product.
To achieve the required sterile conditions, ultrafilter offers a complete
range of products which meet the high demands of the dairy industry
and fulfil the requirement for contact with food according to FDA
regulations.
Sterile conditions can be achieved by
the following actions:

Packaging machinesThe food industry is heading more and more in the direction
of aseptic packaging or filling and away from thermal treat-
ment or preservatives to extend the shelf life.
This relatively new method has the advantage of an absolute
continuous process and a reduction in energy consumption,
a better flexibility to store the products and it also avoids the
necessity for the cooling of the product since the filling takes place under cold conditions.
ultrafilter offers specifically for these applications a large variety of solutions to improve the shelf life of the products without using
additional additives or preservatives.
One solution for this problem is the sterile air box P-SLF. The function of this system is sometimes integrated into the filling machine
by using pre- and sterile filters or the system is used as an external unit.

Infusion solvents, serums, vaccines, plasma. These are only some of the products of the
pharmaceutical industry that are produced to meet the highest standards concerning
quality and purity. ultrafilter offers filter systems which have been developed to match the
requirements of the pharmaceutical industry and biotechnology for numerous applications.
In order to ensure consistent quality of the final products the entire manufacturing
process must be free from any contamination. This aim is reached in a reliable, safe and
cost efficient way by ultrafilter membrane filters.
ultrafilter in thepharmaceutical industry and the biotechnology
Air and gas filtrationThe compressed air in fermentation processes is filtered before it is added to the
fermenter through the vent pipe. Nitrogen which is used for pressurizing tanks should
also be free from bacteria, pyrogenes and any other particles before it comes
in contact with the final product. ultrafilter sterile air filters distinguish themselves
by their inherent hydrophobia, a high dirt hold capacity and a low differential pressure.
The validated sterile depthfilter P-SRF as well as the membrane filters ultrapolymem®
and ultrateflomem® meet the highest quality requirements and have been proven their
performance in thousands of applications.
The fermentation process shown in picture 10 shows how ultrafilter filters are used in
this application.

Water filtrationThere are two relevant standards concerning the water quality for the pharmaceutical and
biotechnology industry:
v WFI, water for injection: This water meets the highest level of requirements. It is
used for the adjustment of product concentration, for the production of WFI steam,
and for the cleaning of ampoules or vials.
v PW, purified water or deionizied water (DI-water) is mainly used for cleaning of
bottles and ampoules or as a supply for fermenters. It is also an addition to lotions,
creams and used in the production of purest steam for sterilization.
For the production of these water
qualities ultrafilter offers the asymetrical
polyethersulfone membrane with retention
rates down to 40 Nanometers (= 0.04 µm).
This filter medium is characterized by
substantially high flow rates and a low
differential pressure.
Compared to traditional filter media
the differential pressure is 4 to 8 times
lower! For the end-user this means the
highest safety at low filtration costs.
Picture 11 shows a typical process of
sterile water treatment.

Chemicals and solventsApart from water, chemicals and solvents are important complementary materials in
the production of pharmaceutical and biotechnical products. Alcohols, actetones and
methylene chlorid are the most frequently used products. All these chemicals are
aggressive and therefore the filtration systems have to be adjusted to meet these
requirements as well as the usual filtration quality.
Picture 12 shows the filtration of chemicals from raw materials to the final product which
the consumer will receive. The following tabulation lists those ultrafilter products which
are recommended for filtration to ensure a highly efficient and consistant quality, even
in the event that the quality of the raw materials should fluctuate.

Sterile filling of pharmaceutical andbiological productsFiltration by membrane guarantees sterility in filling pharmaceutical products. This
ensures an efficient retention of pyrogenes, living microorganisms and particles at a
maximum flow rate. As a prefilter for protecting the membranes ultrapolyplea® depth
filters are used. These filter elements have a high dirt hold capacity and low extractables.
In storage and holding tanks hydrophobic ultrafilter aeration and de-aeration filters
guarantee sterile conditions for storing the sensitive products and exclude a contami-
nation by the ambient air.
The following picture (picture 13) shows the process of sterile filling and the ultrafilter products designed for it.

The filtration of paint and ink is a particle filtration aiming at a consistently high quality of
the paint. In the automotive industry or in the printing industry impurities mean costly
rework or rejections.
In the electronic industry particles can cause read-/write errors at CD-ROMs.
Purity requirements are also growing concerning inks. In order to obtain a higher resolu-
tion of the prints, the nozzles that apply the ink are getting smaller. ultrafiter filter reduce
the costs for rework and maintenance on paint spraying tools effectively because all
foreign particles are removed.
This ensures a high quality of the final product.

High Quality Paint FiltrationNew technologies of paint applications and new paint qualities allow the
end-user to reduce the thickness of the paint layer down to 500–700 µm.
For this reason the quality demand on the paint manufacturer increases.
Gels, foreign particles, fibres or filings have to be removed by a reliable
and save filtration process. This leads to a consistent quality of the paint
and prevents a blocking of the nozzles.
The different types of filters as well as a typical process is shown in
the following diagram.

Filtration of inkIn the filtration process of ink usually a continuous circulation is used. A filter
system has to ensure that the colour of the ink does not change and that
the color pigments are not removed, but disturbing particles only.
ultrafilter depth filters and their numerous different pore diameters always offer
the right solution for your application.
Maximum dirt hold capacities at low differential pressures reduce the costs of
filtration considerably and guarantee an optimum quality and long service life.

particle removal is guaranteed throughout
its entire service life.
For this reason the filter is especially suit-
able for the filtration of compressed gases,
fermentation of gases, technical gases,
tank ventilation and for solvents. ultrapoly-
mem® offers a cost effective alternative to
a PTFE membrane with similiar performance
and durability range against chemicals.

sential at high particle loads. The porosity
level is more than 50% which ensures high
particle and dirt holding as well as a good
flow rate at a low differential pressure.

In the processing of perishable or sensitive products the demands
for hygiene are usually very high. The ambient air is polluted and
can ruin even the cleanest production process if it comes in contact
with the end product without being purified.
Bacteria, viruses, phages, oil mist, water and dust in the ambient
air are the main reasons for the microbiological spoilage of the
products.
Sterile air creates aseptic conditions in pressurized and in open
storage or mixing tanks and in filling machines.
A continuous exchange of the air cushion and a slight overpressure
in this critical area reduces the risk of a secondary contamination
with ambient air.
ultrafilter developed specially for these production processes where
bacteria and phage free air is required the autarkic sterile air box
P-SLF. With eight different sizes from 30 m3/h (18 cfm) to
960 m3/h (566 cfm) it is possible to produce sterile air in the most
cost efficient way. The P-SLF box is available in a mobile and a
stationary version and can be sanitized with saturated steam.
The P-SLF box is used in applications within the food and beverage,
the chemical, the pharmaceutical and the cosmetic industry.
Product description:
The filtration system is a compact unit consisting of a pre- and
sterile filter with a low pressure blower.
The sterile air is transported with a very low overpressure into the
storage tank. This constant air exchange prevents the growth of
bacteria, viruses and phages which the ambient air contains.

Function:
The blower sucks the dry but polluted ambient air (r.H. < 95%) via the air intake (1) into
the chamber (2). The air is cleaned with the prefilter at the upstream side of the blower.
The retained particles cause an increase in the differential pressure. To maintain the
function of the system and to protect the blower (4) a vacuum relieve valve (3) is in-
stalled.
The blower (4) “compresses” the air at about 0.1 bar (1.5 psi). The compressed air is
fed into the sterile chamber (5). The sterile filter retains microorganisms and all kind of
bacteria and/or other contaminants.
To protect the blower there is also a pressure relief valve which opens if the sterile filter
is blocked. At the outlet (11) the sterile air is fed to the tank or an other point of use.
During sterilization of the sterile chamber and the sterile filter elements, the disc
valve (7) needs to be closed to prevent steam entering the blower. To maintain a good
steam quality the steam filter (8) is standard on the P-SLF box. After sterilization the
condensate can be drained out the discharge valve (9 + 10).
* Standard:
220 V/380 V , 50 Hz (P-SLF 0288-0 to 1152-0)
380 V/660 V , 50 Hz (P-SLF 1536-0 to 3072-0)
Also other voltage or frequencies availableon request.
Note:All P-SLF boxes are also available in PN 4version. This means it can be sterilizedwith saturated steam up to 4 bar (58 psi)or a steam temperature of 140°C (284°F).The name of such a box would e.g. be P-SLF 0576-4.

1. The Bubble Point Test
At the beginning of the bubble point test the membrane
has to be rinsed with an adequate wetting agent.
For hydrophilic membranes this is usually water, for
hydrophobic media isopropyle alcohol (IPA) or
an IPA-water mixture depending on the manufacturers
specifications.
After the element has been wetted sufficiently, the
remaining water is drained by the drain valve (V4).
The drain valve (V4), the aeration valve (V3) and the
valves at the upstream (V1) and downstream side (V2) are
closed. The valves V2 and V5 are opened. After that an air
pressure of around 70% of the expected bubble point
value is introduced through valve V2. For each membrane the
bubble point depends on the pore size.
The pressure is being risen by 0.1 bar steps until an even flow of air bubbles rises from
the free end of the tube that ends in a water filled container. Then the bubble point is
reached. The pressure has to be higher than the value given by the manufacturer in order
to prove that the filter element still has integrity.
The bubble point determines the “biggest” pore in the medium.
Test procedures to determinethe integrity of
sterile filter elements.In all critical applications and also all in all validated processes regular testing of the
integrity of the sterile filter elements is necessary. According to cGMP (current Good
Manufacturer Practice) tests have to be run before and after every sterilisation.
These integrity tests are related to destructive tests, e.g. the bacteria challege test.
The results are transfered to non-destructive tests. There are three different test
methods for membrane filters and one for sterile depth filters which are commonly used.
The following tests provide revealing, reproducible and reliable data on the qualities
and the condition of a filter element:
v bubble point test
v diffusion test
v pressure hold test
v DOP-test (dioctyle phthalate) for sterile depthfilters only!
Each of these tests has its very specific
field of relevance, which means that it
is only by the combination of at least two
different test methods, e.g. bubble point
and diffusion test, that a clear statement
concerning the integrity of a filter element
can be made.
The bubble point depends on various
factors:
1. temperature
2. filter medium
3. wetting agent
4. pore size
In order to get reproducible results the
parameters have to be the ones given
by the manufacturers.
Bubble Point Test
66
2. Diffusion test
The diffusion test measures the quantity of air diffusion
through the filter medium. Like in the bubble point test, the
element has to be rinsed with a wetting agent.
After this valves V1, V3, V4, and V6 are closed, V2 and V5
are opened. A pressure of approximately 70–80% of the
bubble point value is entered through valve V2 till it
stabilizes.
The diffusing air volume is measured by an inversed water
filled burette that is in a container with water. If the filter
element works correctly, only a certain air volume per minute
and filter is supposed to diffuse through the filter media.
This value depends on the type of filter, its medium and the
pore size, and will be indicated by the manufacturer.
The diffusion test states the membranes’ “average” pore size.
Diffusion values that are too high or too low may be due to a damaged filter or leakage in the filtration system.
3. The pressure hold test
The principle of the pressure hold test is the same as that
of the diffusion test. Apart from leakages in the membrane
filter even the smallest leakage of the filtration system
can be detected.
A distinction whether there is a leak or whether the mem-
brane lost integrity is not possible.
After a water- or IPA rinsing of the filter element the moisting
liquid is drained through valve V4, then valves V1 and V3 are
closed.
A pressure of approximately 70–80% of the expected bubble
point value is entered through valve V2 and after a short
period of stabilization of about 3 minutes readjusted again.
Valve V6 is kept open during that whole process.
After a certain time the pressure is supposed to drop only by a certain value in order to prove that the integrity of the filter element is
still assured.
The pressure drop does not usually leave the millibar range and therefore it is necessary to have very exact pressure gauges.
The pressure drop depends on pore size, filter medium and wetting agent. Furthermore the temperature has to be kept constant
during the measurement in order to get relevant results.
These three methods can be conducted manually but they require a lot of time and well qualified staff in order to avoid incorrect
measurements.
This is the reason why ultrafilter offers an automatic and sensitive integrity test system, the ultracheck vario®.

4. Dioctyle Phthalate Test (DOP)
The DOP test is only used to test the integrity of sterile depth filters and shows the retention rate of the filter elements.
The testing procedure is described by EN 1822 and by ASTM (American Society for Testing and Materials) D 2986-91.
An aerosol generator is used to produce a paraffin oil smoke with a particle spectrum of 0.1 to 0.5 µm. The test smoke is used to
moist the filter element. A laser particle counter counts the number of particles that pass the filter element. A “sterile” element has to
have a LOG reduction value (LRV) of more than 7 per cm2 filtration area. That means that out of 107 particles only 100 (= 1) particle
is allowed to pass per cm2 of the filtration area. Than the LRV is higher than 7 and the element is considered as “sterile”.
The Filter Test Center (FTC) is used to test the integrity of sterile depth filters.
For this purpose, the device carries out a DOP test (Dioctyle Phthalate test) according
to EN 1822 and ASTM D 2986-91 (see above). The efficiency of the filter element is
displayed.
Ease of operation and a menu driven user interface are the features of the FTC.
All operating sequences are shown in a LCD dispay. This means, the user is always
informed on what is currently going on and which steps have to be taken next.
The device automatically calibrates either after a set period of time or after a restart.
This ensures reliable and reproducible results at any time.
These results are evaluated (good/bad) and logged by a printer or they can be directly
requested via a serial interface to a PC.

The ultracheck vario® is used to check the integrity of membrane filters.
The electric-pneumatic instrument performs a pressure hold test and a bubble
point test. The results are compared to the critical data and a report about
the measurement is printed.
Exchangeable units help to adopt the ultracheck vario® to all types of filters
and pore sizes.
Because of its ease of operation and exact results the ultracheck vario® is
a safe and flexible instrument for the documentation of filter performance and
the intergrity of membrane filter elements.

Your compressed-air supply will become transparent due to the service of the ultrafilter
measurement techniques. We record the pressure, temperature and volume flow of the com-
pressed air on the site and determine the energy consumption of the compressor station.
These data are needed to determine exactly the quality of the compressed air in accordance
with the relevant standards. In case of the residual oil content measurement e.g., ultrafilter
records all liquid and gaseous contaminations in the user’s compressed-air network – down
to the verification limits.
These are services which pay for themselves quickly. The exact analysis of the actual conditi-
on is the optimum basis e.g. for the planning of adsorption dryers or for an enlargement of
existing compressed-air networks and preparation plants.
And – last not least – it provides safety: it ensures you that the compressed air in the
network corresponds to the individual quality requirements.
Saving by planning: The ultraplanning system guarantees replacement parts, such as
filter elements, at a fixed price for three years.
Your maintenance costs can be easily calculated. A further advantage:
ultrafilter is also responsible for the delivery of the filter elements in time.
