UFM160 Series 6" PVDF Hollow Fiber Ultrafiltration Membrane Module


Hongtek UFM160 Series 6" PVDF Hollow Fiber Ultrafiltration Membrane Module are made of high quality modified PVDF hollow fiber ultrafiltration membrane, which has higher chemical stability, oxidation resistance, acid and alkali resistance, and long service life. After special hydrophilic treatment, the PVDF ultrafiltration membrane has permanent hydrophilic properties, which can ensure a high water production flux even at a lower transmembrane pressure. PVDF hollow fiber ultrafiltration membrane uniform void distribution can well overcome the blockage of particles and ensure the stability good quality of produced water. PVDF UF membrane has a high breaking strength and elongation ability, which can effectively reduce the probability of breaking film filaments.

Work principle of PVDF ultrafiltration membrane


● PVDF UF membrane water flow mode is from outside to inside

● PVDF ultrafiltration membrane fiber pore size distribution is uniform and larger filtration area

● PVDF ultrafiltration has strong anti-staining ability, resistant to acid and alkali & long working life

● The filtration rarting of PVDF UF membrane is 0.1 micron, particles are trapped by the membrane wall

● Water, small molecules and ions pass through the membrane walls under pressure to form ultrafiltrate

● Outside to inside flow mode of PVDF hollow fiber UF ensure the stability good quality of produced water
