MBR20 Series Membrane Bioreactor Reinforced PVDF MBR Module for Sewage Treatment

Description

MBR20 Series reinforced PVDF Membrane Bioreactor(MBR) Module is made of modified PVDF material and polyester interlayer support net, which has good water permeability, mechanical properties, chemical resistance and anti-pollution ability, and the filtration rating is 0.1 micron. PVDF MBR membrane module is installed with a hollow fiber ultrafiltration membrane with ID 1.0mm and OD 2.2mm. The filtration method of reinforced PVDF MBR membrane is external pressure, the raw water is driven by the pressure difference and penetrates through the hollow fiber from the outside to the inside in the radial direction. Species such as bacteria, colloids, suspended solids and microorganisms are trapped in the MRB membrane tank.

Work principle of reinforced PVDF MBR membrane

MBR-process.jpg

● High quality hollow fiber PVDF MBR membran ensure the stability good quality of produced water

● PVDF MBR membrane has high chemical resistance, good anti-pollution ability and long service life

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

● MBR membrane is made of reinforced PVDF hollow fiber membrane, has good mechanical properties

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

● PVDF MBR water flow mode is from outside to inside, Negative Pressure Suction, Continuous Aeration


Tech Support
