Ultrafiltration on hollow fiber membrane is a clean, efficient and inexpensive technique for drinking water production, process water production, tap water purification, waste water treatment for recycling/reuse, pretreatment to desalination and other specific applications.
Ultrafiltration often replaces other more conventional treatment techniques and microfiltration as well, as it has the capacity to eliminate not only small particles but also pathogenic germs including microorganisms, viruses, pyrogen and some dissolved organic species.
A hollow fiber membrane is a small plastic tube less than one millimeter in diameter, whose wall is porous.
The pores of S2 Polymem membranes are 0,01 µm size, that is to say 10,000 times thinner than a human hair. Suspended matters, but also micro-organisms and viruses perfectly retained on the surface of the fibers (the smallest micro-organisms and viruses have sizes of 0.2µ and 0.025 µ respectively).
The Polymem ultra filtration cartridges are composed of several thousands of these fibers and offer a huge filtration surface for large volumes treatment.
