1. large capacity UF 2. open frame, easy maintainance 3. chemical cleaning stage by stage 4. high purity product

MOTIAN COMPANY use PVDF as base membrane material, through a special hydrophilic treatment, to make the membrane hold the PVDF good properties (such as good resistance to temperature, oxidation, light aging, acid and alkali, chemical, pollution performance, etc.) meanwhile, it has preferable water flux and anti-pollution performance.

Characteristic of MOTIAN PVDF UF membrane:

1.Good hydrophilicity:

By a special hydrophilic treatment, MOTIAN Company make the PVDF UF membrane has permanent hydrophilic properties. Even at a lower trans-membrane pressure, it also can get high water flux.With uniform pores, MOTIAN hollow fiber UF membrane can remove the micro-organisms, colloids, algae and other can cause turbidity substances. All the modules through an air water inspection to ensure the fibers without broken or leaking.

2.Good mechanical strength:

Through improving the formulation and process, MOTIAN Company makes the PVDF membrane products have good breaking strength and breaking elongation, to ensure no broken occurred in use.

3.Long life, anti-pollution:

MOTIAN COMPANY using high quality PVDF as raw materials, the hollow fiber UF membrane has good advantages of resistance to acid and alkali, organic solvent, grease and light aging. It also has good pollution resistance and strong endurance, it can be washed with various methods in order to remove contaminants and restore membrane flux.
