CUNO’s BevASSURE BDA020 series filter
combines two asymmetrical polyether sulfone
(BDA020) membrane layers together with
Advanced Pleat Technology (APT) construction.
This design results in a robust filter that is
optimized for both long service life and fast flowing
applications, while providing 0.2 µm absolute rated
filtration for sterilizing grade performance.
The BevASSURE BDA020 series filter helps
bottled water and other beverage processors meet
the highest standards for microorganism control.
Combined with CUNO’s range of particle control
and prefiltration filter cartridges, BevASSURE
BDA020 final filters offer bottlers a complete
solution for rigorous contaminant control while
maintaining long service life and low operating
costs.
Durable Design
The BevASSURE BDA020 series filter membrane
and cartridge design innovations result in a highly
durable filter cartridge, capable of secure operation
through numerous cycles of hot water sanitation,
steam sterilization, and chemical based cleaning
and sanitation.
ADVANCED TECHNOLOGIES
Highly Asymmetric BDA020 Membrane
BevASSURE BDA020 filters incorporate a novel
dual-layer BDA020 membrane with a high degree
of asymmetry (Figure 1). When viewed in
cross-section, the membrane contains larger pores
on the upstream surface that gradually taper to
smaller pores towards the downstream surface.
Compared to conventional membranes with a
symmetric pore structure, this structure provides
greater contaminant capacity, since it presents
greater open spaces (void volume) in which to
retain these contaminants. This increase in
capacity leads directly to longer service life. In
addition, the asymmetric structure provides less
resistance to flow, resulting in a lower pressure
drop when compared at a constant flow rate to
competitive filters, allowing a user to employ fewer
BevASSURE BDA020 filters for any given flow
rate.

Advanced Pleat Technology Design
BevASSURE BDA020 filters feature Advanced
Pleat Technology (APT) design for extended
service life. This design technology maximizes
the useful surface area of the filter while
maintaining open flow paths between the media
pleats (refer to Figure 2). By employing the APT
design, the BevASSURE BDA020 filter provides
lower pressure drops, longer service life, and
lower overall operational costs.

ADVANCED PERFORMANCE
Extended Service Life
In the majority of beverage applications, the final
membrane filter is used in a continuous (as
opposed to a batch) operation. Its service life is
measured either by the volume filtered, or the
number of days in service, before becoming
permanently blocked. Filters that provide longer
service life not only reduce direct operational costs,
but also reduce indirect filter costs as well (filter
change-out/installation labor, downtime between
change-outs, filter flushing, etc.). The BevASSURE
BDA020 filter’s combination of highly asymmetric
BDA020 membrane, Advanced Pleat Technology
design, and novel upstream & downstream supports
all work together to maximize the volume of
beverage that can be processed.
Absolute Microbiological Control
The primary purpose of a membrane filter cartridge
in bottled water and beverage processing is to
effectively control even the smallest
microorganisms. BevASSURE BDA020 0.2 micron
rated filters provide superior retention of common
spoilage microorganisms, even at challenge
concentrations that far exceed those experienced
by most beverage producers. BevASSURE BDA020
membrane has been validated for complete
retention of

(ATCC 19146)
Novel Media Support Design
BevASSURE BDA020 filters employ a design that
results in higher beverage flow versus pressure
drop compared to competitive filters. This CUNO
development combines the high flowing BDA020
membrane with special support layers upstream
and downstream of the membrane. When
combined with the previously mentioned
Advanced Pleat Technology, this feature greatly
increases flow per cartridge, and results in lower
overall operational costs.

Fast Flow Rates at Low Pressure Drops
CUNO has combined three key technological
advances to provide a fast flow rate per unit of
pressure drop. These three technologies, Advanced
Pleat Technology (APT) design, a novel upstream
and downstream support design, and a highly
asymmetric microporous membrane, afford users
with faster process flow rates using fewer filters as
compared to alternative filters.
When installed in an existing system with a fixed
flow rate, BevASSURE BDA020 series filters exhibit
a lower pressure drop compared to alternative
filters.
Since filter change-out is usually tied to a terminal
differential pressure drop (typically between 20 and
35 psid), employing filters that exhibit a
pressure drop can result in
longer
filter service life.

CUNO Filter Housings
A specialized range of filter housings is available to
meet the needs of the food & beverage industry.
They provide easy access for filter change-out and
afford a secure seal between filter and housing to
help prevent fluid bypass. All housings are
constructed using 316L stainless steel to maximize
corrosion resistance. Internal surfaces of the
housings are polished to 20 micro-inch Ra to limit
microbial adhesion and provide easy cleaning.
CUNO also offers custom-design, fully automated
filtration skids and mobile units. These units can
incorporate membrane housings, prefilter housings,
SIP and CIP systems along with all necessary
piping, valves, monitoring devices and computer
controls for reliable, hands-free operation.
Fully Automated Filtration Skids
Prefiltration Selections
Many bottling applications employ a prefilter and
final filter in series to achieve maximum
performance and economy. Prefilters are used to
protect and extend the life of more expensive final
filters. CUNO offers a number of premium prefilter
choices: Betafine™ XL pleated filter cartridges,
PolyNet™ depth filter cartridges and
LifeASSURE™ membrane filter cartridges.
Betafine XL filter cartridges (Literature
LITCBFXL) feature CUNO’s Advanced Pleat
Technology maximizing the accessible filter area
and supplying exceptionally high flow rates.
Those preferring depth-style filters can select
from CUNO’s PolyNet prefilter family (Literature
LITCPN1) which employs an advanced media
design that enhances flow while extending
service life. For additional bioburden control,
CUNO’s LifeASSURE filter cartridges (Literature
LITCLAFB1), featuring dual-zone membrane, are
designed to deliver the ultimate in final membrane
protection and bioburden reduction.
