UFM250 Series 10" PVDF Hollow Fiber Ultrafiltration Membrane Module

Description

Hongtek UFM250 Series 10" PVDF Hollow Fiber Ultrafiltration Membrane Module is an international advanced technology for liquid separation and water purification. Hollow fiber UF membrane is made of modified PVDF with micropores evenly distributed on the membrane wall, the feed liquid flows into or out of the membrane under the influence of pressure. Solvents or small molecules can permeate through the membrane to become a pure liquid, while macromolecules, colloidal particles, and bacterial are retained and flowed out by the circulating fluid to become a concentrated solution. PVDF UF membrane module is a ideal filter material used for water treatment.

Work principle of PVDF hollow fiber UF membrane

UFM250.jpg

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

● PVDF UF 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

● PVDFhollow fiber UF membrane has strong anti-staining ability, resistant to acid and alkali & long working life

● Outside to inside flow mode of PVDF ultrafiltration membrane ensure the stability good quality of produced water
