In the food and beverage industry membrane housings are often used in systems to reduce or eliminate microbials to make products safe for consumption and to extend their shelf life. We produce membrane housings for membrane filtration in the food industry for liquid-containing products such as juice, beer, soy, whey, milk, milk powder, chocolate etc.
Wila membrane housings benefits
Our base range membrane housings are designed for 4”, 6” and 8” membranes, 1 to 6 elements, with pressure rating up to 64 bar. The 4” and 6” housings’ blind and permeate ends consist of standard dairy clamp ferrule connections while a slightly modified aseptic clamp assembly is used for the 8” low pressure housing. Both higher pressure 8” housing versions have O-ring sealed dished ends with a special circlip-like locking ring for easy membrane replacement and cleaning.
The membrane housings’ feed and retentate side ports are made by collaring the housing shell, which gives smooth and easy to clean openings. All materials, welds, grinding and other finish is of the highest dairy standards. Optionally, due to their design, optimized manufacturing processes and high quality, the membrane housings can be delivered with a certificate of compliance with the 3A hygienic standard.
