CUNO’s BevASSURE BNA020 series filter
features a new asymmetrical polyether sulfone
(PES) membrane 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 rated filtration for superior
removal of microorganisms.
The BevASSURE BNA020 series filter helps
bottled water and other beverage processors meet
high standards for microorganism control.
Combined with CUNO’s range of particle control
and prefiltration filter cartridges, BevASSURE
BNA020 series final filters offer bottlers a complete
solution for rigorous contaminant control while
maintaining long service life and low operating
costs.
Durable Design
The BevASSURE BNA020 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
and chemical based cleaning and sanitation
protocols.
ADVANCED TECHNOLOGIES
Highly Asymmetric BNA020 Membrane
BevASSURE BNA020 series filters incorporate a
novel single layer PES 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 BNA020 series filters for any given
flow rate.

Advanced Pleat Technology Design
BevASSURE BNA020 series 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 BNA020 series
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
BNA020 series filter’s combination of highly
asymmetric PES membrane, Advanced Pleat
Technology design, and novel
upstream/downstream supports all work together to
maximize the volume of beverage that can be
processed.
Advanced 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 BNA020 series 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.

Novel Media Support Design
BevASSURE BNA020 series filters employ a
design that results in higher beverage flow versus
pressure drop compared to competitive filters.
This CUNO development combines the high
flowing PES 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 the fastest 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.

series filters can be significantly lower compared
to competitive 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

lower

life.
Alternatively, in a new system when determining
the number of filters needed to provide a desired
flow rate at a given pressure drop, faster flowing
filters will result in smaller, more economical
systems.
Consider the following example:
The number of 30” filters needed to provide a 45 GPM
flow with a clean pressure drop of 1 psid (170 lpm flow @
69 mbar)
CUNO BevASSURE BNA020 5 filters
Competitor A 8 filters
Competitor B 14 filters
Competitor C 8 filters
As the example above illustrates*, the nearest
competitor requires significantly more 30” filters to
provide the same flow rate and pressure drop.10"

Automated Integrity Testing - CUNOCheck™2
A full range of non-destructive integrity tests can be
easily and automatically performed with the
CUNOCheck 2 integrity test instrument. The
CUNOCheck 2 and MiniCheck integrity test
instruments provide fast, reliable and accurate
automated integrity testing of BevASSURE BNA020

document LITCCC2.
Prefiltration Selections
Many bottling applications employ a prefilter and
final filter in series to achieve maximum
performance and economy. Prefilters are used to
help 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.
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
they ensure that BevASSURE BNA020 filter
cartridges are sealed securely to eliminate the
possibility of 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.
