3M BDA020 Specifications

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

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
