MBR25 Series Reinforced PVDF Hollow Fiber MBR Membrane Module is a membrane unit is introduced into traditional sewage biological treatment technology of the new processing technology. PVDF MBR membrane separation unit in replace of traditional secondary sedimentation pool function, with further removal of organic matter, nitrogen and phosphorus, it is the most advanced and efficient water treatment technology. PVDF hollow fiber MBR is made of modified PVDF material, with high flux, good chemical resistance and pollution resistance. The polyester interlayer support net greatly increases the mechanical strength of the membrane silk. The ID and OD of the reinforced PVDF hollow fiber membrane are 1.0mm and 2.2mm, and the filtration rating is 0.1μm. Outside to inside flow direction of PVDF hollow fiber MBR, lead to bacteria, colloids, suspended solids and microorganisms are intercepted to achieve a good filtering effect.

Work principle of PVDF hollow fiber MBR membrane
● High quality PVDF hollow fiber MBR ensure the stability good quality of produced water
● The filtration rarting of MBR membrane is 0.1 micron, particles are trapped by the membrane wall
● PVDF MBR membrane has high chemical resistance, good anti-pollution ability and long service life
● Water, small molecules and ions pass through the membrane walls under pressure to form ultrafiltrate
● MBR membrane module is made of reinforced PVDF hollow fiber membrane, has good mechanical properties
● PVDF hollow fiber MBR water flow mode is from outside to inside, negative pressure suction, continuous aeration
