3M Purification Food and beverage markets LifeASSURE BLA Series cartridge filters ™ Robust Nylon 6,6 pleated prefilters for beverage filtration New name for CUNO LifeASSURE FB cartridges Multi-zone microporous membrane design and Advanced Pleat Technology construction Exceptional protection of downstream membranes Extended service life for lower running costs and enhanced flexibility in filtration selection LifeASSURE BLA Series filters Upstream Fluid flow Downstream LifeASSURE™ BLA filter cartridges, formerly known as CUNO LifeASSURE FB, are 3M Purification’s advance in membrane filter technology. Encompassing two leading-edge processes, multi-zone microporous membrane manufacture and APT (Advanced Pleat Technology) pleating construction, the LifeASSURE BLA series of filters offers unmatched protection of final membrane filters, as well as exceptionally long service life. Designed with a pleated Nylon 6,6 membrane in an allpolypropylene cartridge construction, LifeASSURE BLA filters are ideally suited for a wide range of filtration and clarification applications in the beverage industry. Optimal system performance LifeASSURE BLA filters can be used as either final filters for spoilage organism removal or as a prefilter. LifeASSURE BLA filters protect and extend the service life of 3M Purification‘s LifeASSURE BA, BNA and BDA final filters, as well as other membrane filters. LifeASSURE BLA filters will: ■ increase final filter life substantially, often by 10 times or more, ■ decrease filter change-outs, greatly reducing filter costs, ■ significantly reduce effluent microorganism content. Multi-zone microporous membrane technology LifeASSURE BLA filters incorporate 3M Purification’s multi-zone microporous membrane technology. It allows unmatched flexibility in creating a multi-zone membrane that offers the maximum in contaminant holding capacity while maintaining a high retention efficiency. The SEM photograph on the left shows that the single-layer LifeASSURE BLA membrane consists of an “open” zone on the upstream side of the membrane and a “tighter” zone on the downstream side. In effect, the open zone acts as a prefilter by capturing larger particles and colloids while the tighter zone provides the retention of smaller contaminants. This multi-zone structure eliminates dual-layer membrane construction to provide a larger surface area, significantly increased contaminant holding capacity and longer service life. Features and benefits Multi-zone microporous nylon membrane • Increased contaminant capacity • Extended service life • Maximum membrane protection • Lower total filtration costs Advanced Pleat Technology (APT) construction for extremely high surface area • Higher throughputs and longer service life • Lower total filtration costs 100% Integrity tested in manufacturing • Ensures proper installation and operation True membrane construction • Significant reduction of microorganisms Approved for food contact use • Complies with European and US regulations 2 Robust construction • Stable long service life in harsh beverage filtration environment LifeASSURE™ BLA Series APT construction advantage LifeASSURE BLA filters also feature 3M Purification’s Advanced Pleat Technology (APT) construction for extended service life. This design technology maximises the useful surface area of the filter while maintaining proper flow paths between media pleats. By employing as much as 50 % more effective surface area than competitive filters (see chart 1), the LifeASSURE BLA filter provides lower pressure drops, longer service life and lower overall filtration costs. Figure 1: LifeASSURE™ BLA‘s Advanced Pleat Technology (APT) configuration Significant micro-organism reduction 3M Purification’s LifeASSURE BLA filters consistently exhibit a greater reduction of micro-organisms than competitive filters that are either constructed of glass or polypropylene fibres or filters that are constructed with non-integral membranes. For effective filtration and clarification of beverages, micro-organism reduction is a critical parameter resulting in economical, reliable filter systems. In tests with Brevundimonas diminuta (considered one of the smallest bacteria) LifeASSURE BLA 020 grade filters exhibited an average log reduction value (LRV)* of 7.3 and the LifeASSURE BLA 045 grade filters exhibited an average LRV of 3.5. Optimised for service life and effluent quality As the data in charts 2 and 3 demonstrate, LifeASSURE BLA cartridges are designed to provide both enhanced service life and performance. When compared to competitive products, the available grades of LifeASSURE BLA filters allow the user to select equivalent effluent quality with vastly superior life or improve the effluent quality with reduced, yet competitively superior, service life. Either way, the result is the same, LifeASSURE BLA filters allow significantly more throughput than the competitive filters and provide up to double the service life.

Filtration selection is highly dependent on: ■ the nature of the fluid , ■ the particulate/colloid content of the fluid, ■ the amount of pretreatment or clarification of the fluid and ■ if present, the rating of any downstream membrane filter being protected The table below is provided as a guide to prefilter selection, although actual process conditions may dictate the use of a more open or closed prefilter than specified below. Prefilter selection can be aided by smaller scale pilot tests or flow decay studies using membrane discs. Consult 3M Purification Scientific Applications Support Services (SASS) or 3M Purification Technical Sales for more information.

Available in both 0.65 μm and 0.45 μm retention ratings, LifeASSURE BA and BNA cartridges are the filters of choice for discerning brewers and wine makers. LifeASSURE BDA020 and BNA020 filters These filters are typically employed as the final filter in various water applications. They are constructed with a PES membrane and polypropylene components. LifeASSURE BDA020 grade filters provide complete retention (1 x 107 CFU’s/cm2) of Brevundimonas diminuta as defined by the FDA. LifeASSURE BNA020 grade filters provide a minimum titer reduction of 1 x 105 CFU’s/cm2 of Brevundimonas diminuta. 4 LifeASSURE™ BLA Series The LifeASSURE BLA filter construction results in a higher per-cartridge flow rate at the same pressure drop when compared to competitive filters. This can reduce filter costs in two ways: Change-out filters less frequently For existing applications at a given flow rate, filter cartridges with more surface area per cartridge have a lower flux (flow per unit surface area) than those filter cartridges with less surface area. Since service life is inversely proportional to flux (lower flux = longer service life) in most applications, LifeASSURE BLA filter cartridges provide longer service life and require fewer cartridge change-outs. Reduce filter housing costs For new applications (where filter housing size is selected based on a desired “clean” initial pressure drop), filter cartridges that provide a higher flow rate per cartridge at a given pressure drop will require fewer cartridges and hence a smaller filter housing to complete the task.

Conducting an installation integrity test assures the user that the filter is installed and sealed correctly in the filter housing and is ready for service. Unlike other filters, LifeASSURE BLA filter cartridges are 100% tested for integrity in manufacturing prior to shipment. Additionally, LifeASSURE BLA filter cartridges are integrity testable in situ by the user. For integrity test procedures and values, please consult 3M Purification. Sanitation and sterilisation The use of hot water (80 to 90 °C) sanitation or steam (121 °C) sterilisation are common strategies employed in beverage production to maintain clean systems. LifeASSURE BLA filters are constructed with Nylon 6,6 membranes optimised for thermal stability to ensure resistance to hot water or steam cycles. 5 10 15 20 25 Flow Rate (lpm) 30 BLA 045 BLA 020 BLA 080 BLA 065 35 40 Recommended cleaning parameters NaOH concentration 2 % by weight Maximum temperature 60 °C Flow rate 11 lpm Duration 30 minutes Longer life with caustic cleaning Cleaning solutions, such as sodium hydroxide, can effectively reduce the impact of beverage colloids in plugging membrane filters. LifeASSURE BLA filters, as with LifeASSURE BA filters, can be cleaned with a dilute caustic flush, reducing differential pressure build up and extending service life. 5 LifeASSURE BLA Series cartridge specifications Standard Cartridge Polysulphone reinforcing ring Various O-ring materials End cap adapter Multi-zone media LifeASSURE BLA filter cartridges are constructed of a single-layer, Nylon 6,6 microporous membrane pleated with polypropylene upstream and downstream support materials.
