Hollow fiber ultrafiltration membrane is using polypropylene material with special silk membrane process, the average pore size 0.01- 0.1 micron, can enrichment and separation of the particles in the water, colloid, macromolecular substances such as organic matter, intercept bacteria, heat source, the algae.Has a large water flux, not easy jam, can use repeatedly washing, etc. First, the functions and features: 1 concentration and separation of water and macromolecules, particles, colloids , organics, retain bacteria and algae . 2 triple mode rejection macromolecules : a) adsorption pores in the membrane ( an adsorption ) ; b) in the micropores are removed stays (blocking ) ; c) is mechanically retained on the membrane surface High precision filter , filter pore size of 0.01 microns , to ensure drinking water safety. 3 silk membrane special production process technology ( hollow fiber membranes with high-quality packaging materials made of high packing density advantages of technology products ) to ensure water flux , clogging . 4 filter can be washed repeatedly , long life. 5 drinking water taste good , no smell, the smell . 6 Good hydrophilic , anti-pollution ability, and less fouling . Second, the ultra filter performance : 1 , high strength, acid and alkali, corrosion-resistant bacteria , good heat resistance ; 2 non-polar surface , without any adsorption ; 3 large specific surface area per unit volume of fill density ; 4 microporous uniform pore morphology of the crack shape retention rate than the hole-type membrane high flux ratio hole-type membrane , stable performance . Third, the main technical parameters: 1 microporous average pore size : 0.01μm 2 film Dimensions : diameter 450μm, thickness 40 ~ 50μm 3 Longitudinal Tensile strength : 120Mpa 4 pH value: 0 ~ 14 5 rupture strength : 1.0 MP 6 Recommended working pressure : ≤ 0.25 MPa 7 Interface: Plug-in (50G membrane shell -specific ) 8 Filter by: external pressure
