LifeASSURE BW

Membrane Filters for Bottled Water Service

LifeASSURE BW BLA100 filters have been tested and certified by NSF International to Standard 53. This standard was developed in conjunction with the bottled water industry to certify filter performance in removing

Cryptosporidium

meets EPA and CDC recommendations. LifeASSURE BW filters are an effective

means of providing microbiological control in water without the need for ozone. Ozone can generate unwanted disinfection by-prod ucts, such as bromate, leading the EPA to introduce regulations restricting the level of bromate in drinking water to <10 mg/L (10 ppb). The International Bottled Water Asso ciation (IBWA) recommends membrane filtration as an option in providing microbio logical control, without the use of ozone, as part of a “multi-barrier” approach to water safety.

NSF International

NSF International is a widely respected independent certification organization and the accepted authority in evaluating filter claims related to water and public health. Only products tested and certified by NSF are allowed to carry their mark. LifeASSURE BW BLA100 has been tested and certified by NSF to Standard 53 for reduction of cysts. This inde pendent certification assures the rigor, reproducibility and impartiality that the bottled water indus try has come to expect from NSF.

FlexN™ Membrane

LifeASSURE BW membrane filters incorporate CUNO’s advanced FlexN membrane technol ogy*. It allows unmatched flexibility in creating a multi-zone membrane that offers the maxi mum in contaminant holding capacity while providing very high per-cartridge flow rates. The cross-section SEM photograph shows that a single layer of LifeASSURE BW 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 are a prefilter by capturing larger particles and microorganisms while the tighter zone re tains smaller microorganisms. This multi-zone structure eliminates the need for a dual layer membrane or thick, fibrous filter media com monly used in other filter cartridges. The result? LifeASSURE BW filters provide more membrane surface area per cartridge, faster cartridge flow rates and longer service life.

Microorganism Reduction

Microorganism control is a critical parameter in preparation of quality bottled or beverage grade water. LifeASSURE BW membrane filters consistently exhibit a greater reduction of microorganisms than competitive filters. In tests conduced with

fluorescens

(a typical heterotrophic plate count, or HPC, organism) LifeASSURE BW BLA100 grade filters exhibited retention far exceeding that of similarly rated filters (Table

1.).

Even in tests with (considered one of the smallest bacteria) LifeASSURE BLA020 and BLA045 grade fil ters exhibited log reduction values (LRV) significantly higher than similarly rated filters (Table 2.)

MaxMedia™ Construction

LifeASSURE cartridge filters also feature CUNO’s innovative MaxMedia construction for extended service life. This design technology maximizes 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, the LifeASSURE BW filter pro vides lower pressure drops, longer service life and lower overall filtra tion costs.

Optimized Service Life

As the data in Chart 1 and Tables 1 & 2 demonstrate, LifeASSURE BW cartridges are designed to provide both enhanced ser vice life without sacrificing effluent quality or microorganism retention. A laboratory study was conducted to measure the relative ser vice life of filters marketed as cyst reducing

ferential pressure of 20 psid was observed.

Installation Integrity Test

LifeASSURE BW membrane filters are 100% integrity tested manufacturing. An in situ in stallation integrity test, a non-destructive measurement of a filter’s ability to function as intended, can be performed by the user upon installation. Conducting an installation integ rity test assures the user that the filter is installed and sealed correctly in the filter housing and is ready for service. For installa tion integrity test procedures and values, please consult CUNO document LITTDCO3.
