Column hollow fiber ultrafiltration membrane modules with H-TIPS making method UOT640

Continuous Membrane Filtration (CMF) refers to a membrane filtration unit specially used for water treatment and reuse, reverse osmosis and nanofiltration pretreatment projects, and the treatment of materials with relatively high turbidity.
The CMF system adopts a highly anti-pollution hollow fiber membrane element with a unique structure and a unique air-water double washing process technology, and is equipped with specially designed pipeline valves, self-cleaning units, dosing units and automatic control units, etc., forming a closed circuit Continuous operating system. The CMF system is particularly suitable for filtering tap water, groundwater, surface water and municipal sewage after biochemical treatment to remove impurities such as bacteria, microorganisms and suspended solids. The purified water is clear and transparent, and the turbidity is close to zero.

The Principle

MF column type membrane filtration is a pressure actuation membrane separation process, it can separate the particulate matter from the liquid of the dissolved component. Highly efficient removal of Colloid, silt, algae,Cryptosporidium, Giardiasis Tyzzer, coliform, bacterium and majority virus, the elimination rate is 4~6 lg.
