LifeASSURE™ BNA Series Filter Cartridges

Filter Cartridges for Beverage Microbiological Stability

Controlling the spoilage microorganism population prior to bottling is critical for many beverage processors. Eliminating these

microorganisms, while keeping other beverage properties unchanged, is of vital importance. Of equal importance, however, is attaining

long on-stream filter cartridge service life and driving down operating costs associated with filtration.

3M Purification Inc. has solved this demanding problem with the creation of the LifeASSURE™ BNA

series of filter cartridges. LifeASSURE BNA filter cartridges encompass leading-edge technologies that

not only provide the highest degree of microorganism control, but do so in an extremely durable and

long-lasting design.

LifeASSURE BNA filter cartridges employ a highly-asymmetric polyether sulfone (PES) membrane

that delivers excellent spoilage microorganism retention while greatly minimizing any organoleptic

interference. This highly durable membrane/cartridge design withstands repeated exposure to hot

water sanitation and steam sterilization as well as common chemical cleaning and sanitizing agents.

Complementing this high-performance membrane are 3M Purification Inc.’s Advanced Pleat

Technology (APT) design and an upstream and downstream support design. All three work in

concert to provide an increased flow rate at a lower pressure drop, resulting in smaller

filter cartridge assemblies with extended service life and a lower overall operational

costs.

ADVANCED TECHNOLOGIES

Highly Asymmetric PES Membrane

LifeASSURE BNA filter cartridges incorporate a novel 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 filter cartridges, allowing a user to

employ fewer LifeASSURE BNA filter cartridges for any given flow rate.

Advanced Pleat Technology (APT)

LifeASSURE™ BNA filter cartridges feature Advanced Pleat Technology (APT) design for extended

service life. This design technology maximizes the useful surface area of the filter cartridge while

maintaining open flow paths between the media pleats (refer to Figure 2). By employing the APT

design, the LifeASSURE BNA filter cartridge provides lower pressure drops, longer service life, and

lower overall operational costs than competitive filter cartridges.

Novel Upstream/Downstream Support Design

LifeASSURE BNA filter cartridges employ a design that results in higher beverage flow versus

pressure drop compared to competitive filter cartridges. This unique 3M Purification Inc.

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 filter cartridge, and results in lower overall

operational costs than competitive filter cartridges.

ADVANCED PERFORMANCE

Extended Service Life

In the majority of beverage applications, the final membrane filter cartridge 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. Filter

cartridges that provide longer service life not only reduce direct operational costs, but also reduce indirect filter cartridge costs as well

(filter cartridge change-out/installation labor, downtime between change-outs, filter cartridge flushing, etc.). The LifeASSURE BNA filter

cartridge’s unique combination of highly asymmetric PES membrane, Advanced Pleat Technology design, and novel upstream/downstream

support design, all work together to maximize the volume of beverage that can be processed. Chart 1 depicts the service life performance of

the LifeASSURE BNA filter cartridge compared to various competitive filter cartridges. A surrogate solution was employed to mimic beverage

plugging characteristics at an increased rate.

As the chart demonstrates, the LifeASSURE BNA filter cartridge’s unique design provided more than twice the throughput of the nearest

competitor, greatly reducing overall filtration costs.

Reliable Microbiological Control

(

(

The primary purpose of a membrane filter cartridge in beverage processing is to effectively control spoilage microorganisms. LifeASSURE™

BNA 0.45 micron and 0.65 micron rated filter cartridges provide superior retention of common spoilage microorganisms, even at challenge

concentrations that far exceed those experienced by most beverage producers (typically 1,000,000 to 10,000,000 cells per cm2 of membrane

area).

Fast Flow Rates at Low Pressure Drops

3M Purification Inc. has combined three key technological advances to provide the fastest flow rate per unit of pressure drop. These three

technologies, a highly asymmetric microporous membrane, Advanced Pleat Technology (APT) design, and an upstream and downstream

support design, afford users with faster process flow rates using fewer filter cartridges.

Consider the following example:

Initial clean pressure drop (water) for a 30” filter cartridge flowing at 20 gpm (76 lpm)

3M Purification Inc. LifeASSURE BNA045 0.75 psid (52 mbar)

Pall OenoPure “GB” * 1.92 psid (132 mbar)

As the example illustrates, LifeASSURE™ BNA filter cartridges have a considerably lower pressure drop at a given flow rate when compared

to competitive filter cartridges. Since filter cartridge change-out is usually tied to a terminal differential pressure drop (typically between 20

and 35 psid), employing filter cartridges that exhibit a lower initial pressure drop can result in longer filter cartridge service life.

Alternatively, when determining the number of filter cartridges needed in a new system to provide a desired flow rate at a given pressure

drop, faster flowing filter cartridges will result in smaller, more economical systems.

Consider the following example:

Number of 10” filter cartridges† needed to provide a 20 gpm flow with a clean pressure drop of 1 psid (76 lpm flow at 69 mbar)

As the example above illustrates, the nearest competitor requires more than twice as many filter cartridge elements to provide the same flow

rate and pressure drop.

Durable Design

The LifeASSURE BNA filter membrane and filter 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.

Prefiltration Selections

Many bottling applications employ a prefilter and final filter cartridge in series to achieve maximum performance and economy. Prefilter

cartridges are used to help protect and extend the life of more expensive final filter cartridges. 3M Purification Inc. offers two premium

prefilter cartridge choices: Zeta Plus™ H Series depth filter cartridges and LifeASSURE™ BLA series membrane filter cartridges. Zeta

Plus™ MH series dual zone H Series filter cartridges (Literature 70-0201-8864-8) have long been used in clarifying fine wine in both cellar

operation and in-line to the bottler. Customers preferring cylindrical prefilter cartridges can select from 3M Purification Inc.’s LifeASSURE BLA

series prefilter cartridge family (Literature 70-0201-8712-9). Containing a dual-zone membrane, LifeASSURE BLA Series filter cartridges are

designed to deliver excellent throughputs with high flow rates, while providing the ultimate in final membrane protection.

3M Purification Inc. Filter Cartridge Housings

A specialized range of filter cartridge housings is available to meet the needs of the food & beverage industry. The housings provide easy

access for filter cartridge change-out and ensure that LifeASSURE™ BNA 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. 3M Purification Inc. 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.
