Functions and features:1. Concentration and separation of macromolecules in water, particulates, colloids, organics, trapped bacteria, algae, and so on.2. The triple ways interception macromolecules:a) adsorption in the membrane pores (primary adsorption);b) remain in the micropores is removed (blocking);c) in the film surface is mechanically entrapped3 special film silk production technology to ensure that the water flux, and clogging.Filter can be washed repeatedly, long life.Second, the ultra-filter performance:High strength, acid and alkali resistance, the bacterial corrosion resistance, good heat resistance;2 non-polar surface, and no adsorption;3 large specific surface area the filling density per unit volume;4. Uniform microporous and the micropore shape crack shape, the retention rate is higher than the round hole microporous membrane large circular channels microporous membrane flux ratio, stable performance.
