Work principle of PVDF hollow fiber UF membrane
● PVDF hollow fiber UF membrane water flow mode is from outside to inside
● PVDF ultrafiltration membrane ensure the stability good quality of produced water
● PVDF ultrafiltration membrane fiber pore size distribution is uniform and larger filtration area
● Water, small molecules and ions pass through the membrane walls under pressure to form ultrafiltrate
● The filtration rarting of PVDF UF membrane is 0.1 micron, particles are trapped by the membrane wall
● PVDF hollow fiber UF membrane has strong anti-staining ability, resistant to acid and alkali & long working life
