Cluster Filter System for Cold Sterile Filtration

The Pall World
Pall Corporation is a world leader in the design, production and supply of filters,
membranes and systems for the filtration and separation of liquids and gases.
With an annual turnover of two billion dollars, we are able to handle major
projects on a safe and sustainable platform.

The advantages of the CFS
principle
The unique cluster principle offers thebrewery significant advantages, primarily
these are:
• Prolonged service life
• In-situ integrity testing• Individual cluster integrity diagnosis• Specific rinsing• High specific flux velocity• Short rinsing time
• Constant stream over all cartridges

The principal of CFS• Minimized water consumption

Pall CFS (Cluster Filter System) has been inindustrial use since 1995, and is today thebrewing industry’s reliable, economic
successful technology for the cold
stabilization of beer. Successful membrane
filtration of beer requires two somewhat
opposite processes to take place:• Fast changing of the filter element®

• Low and gentle flux during beer filtration,
to ensure the beer is not affected by thedynamic forces across the membrane• High and robust flux during rinsing andcleaning
Generally, membrane systems are acompromise of these two requirements. The
patented CFS technology offers the brewery
an alternative that optimizes both criteria.
Cluster filtration, groups filter elements intoclusters. With each cluster having its own
individual outlet valve.
During filtration all clusters are open.
Cleaning, sterilization and integrity testing isdone cluster by cluster.

• Controlled backflush• Minimized beer losses• High biological safety• Permanent availability
The combination of the in-situ integrity
testing of the cluster filter and the 100%
integrity testing of the membrane cartridges
during manufacture lends the CFS to form arobust part of any brewery’s HACCP
procedures.
The system not only ensures themicrobiological consistency of the brandproduced for consumers, but also acts as aneffective indicator of any manufacturing
process variation.

System engineering
The Pall CFS system is designed as a standalone unit, to be installed directly upstreamof the filling line without any requirement fora buffer plant. It is a complete independent
process unit which comprises of:• Filter vessel• Piping and connections• Membrane cleaning unit (CIP)• Integrity testing• Control panel
Pre-manufacturing programming and fullskid SAP testing results in a very shortinstallation and start up time for the skid
based equipment.
Once installed the effective Pall cleaning
procedure allows long life of the Ultipor® N66
cartridges and if necessary the recovery ofblocked cartridges.
The brewery can be assured of the
microbiological security of the system due toits hygienic design, ease of integrity testing
and full automation, that allows the line totypically be handled by filling staff.

Pall in the Brewery - Cluster Filter System for Cold Sterile Filtration
CFS - Cold sterile filtration at the very last stage of brewing process, directly in front of the filling line
for the safe and complete removal of all beer spoiling micro-organisms from the productConsistent high quality beerand reduced operationalcosts

Cost savings begin with:

The beer quality through a Pall membrane
system is unquestionable, there is noimpact on:• Reducedwaterconsumption
incomparison to traditional filtration andpasteurization• Taste• Reduced energy costs in comparison topasteurization• Foam• Reduced product losses in comparison to
flash or tunnel pasteurization

Further benefits can be measured interms of:
• Availability of the system, which ismaximized by the individual shutdown ofclusters, for offline integrity testing• Biological safety and risk management by
on-line documentation of all relevant
process parameters• High sensitivity integrity testing carried out
in cluster formation• Color• Hygienic design of the system

Oxygen up take is < 0.02 ppm from theprocess start.

• Compact engineering, minimizing floor
space requirements
Significantly the CFS system can offer
unprecedented traceability of productbatches. This is carried out by continuous
data logging and documentation of theprocess through the automated system.

More value per hectolitre
CFS offers value to the brewery in an individual way it offers:• High quality beer
• A low overall cost option in comparison totraditional filtration and pasteurization• Superior biological control given by the cluster
integrity testing technique• Maximum availability of the system, due tocluster cleaning, sterilization and integrity
testing optimization• Minimum manpower can be realised throughfull automation
