PVDF 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, good mechanical strength, larger surface filtration area, easy to backwash and long service life. The filtration rating of PVDF hollow fiber ultrafiltration membrane is 0.1 micron and outside to inside membrane water flow mode, guarantee the stability good quality of produced water. PVDF ultrafiltration membrane module is widely used in RO system pretreatment, industrial wastewater deep treatment reuse, reclaimed water reuse, sea water desalination, residential and commercial water treatment etc.
