3M™ LifeASSURE™ BA series cartridge filter membrane technology allows casting of an integral membrane onto a variety of substrates. The result is a microporous membrane with characteristics such as increased flow and reduced pressure drop, tailored to provide ideal performance for the intended application.
The LifeASSURE™ BA Series Filter Cartridge is designed for precise clarification of fluids in food and beverage applications by effectively reducing contaminating yeast, molds and most spoilage bacteria from liquids.
Decreased Filtration Costs
Cartridge filter life is directly proportional to filter area and inversely proportional to face velocity (flow rate per filter area). For most beverages, when the filter area is doubled at the same flow rate, the throughput is increased by two and one-half times. With the high surface area of LifeASSURE™ BA Series Filter Cartridge, the face velocity can be lower and throughput greater than with lower surface area cartridges.
LifeASSURE™ BA Series Filter Cartridges withstand a mild alkaline flush after each days run (typically 30 minutes of forward recirculation of 2-3% NaOH at 140 °F [60 °C]). Throughputs are improved from 3 to 10 times for most beverages, depending on when the cleaning cycles are started.
Users can also perform integrity tests in-situ to ensure performance. Bubble point pressure, diffusion flow, or pressure hold procedures can be performed while filters are in the housing, thus demonstrating the cartridge’s efficiency to filter spoilage microorganisms on-line.
