High definition Membrane Bioreactor Process - MCR Membrane Module Reinforced PVDF BM-SLMCR-20 RO Pretreatment – Bangmo
High definition Membrane Bioreactor Process - MCR Membrane Module Reinforced PVDF BM-SLMCR-20 RO Pretreatment – Bangmo Detail:
Product Overview
Submerged ultrafiltration (MCR) Technology is a water treatment technology which combines membrane technology and physico-chemical precipitation process. High-precision sludge-water separation of outlet from coagulation sedimentation tank can be done by submerged ultrafiltration (MCR), high filtering precision of memrbane insures high quality and clear water outlet.
This product adopts reinforced modified PVDF material, which will not peel or break during backwashing, meanwhile it has good permeable rate, mechanical performance, chemical resistance and anti-fouling ability. ID & OD of reinforced hollow fiber membrane are 1.0mm and 2.2mm respectively, filtering precision is 0.03 micron. Filtering direction is outside-in, that is raw water, driven by differential pressure, permeates into the hollow fibers, while bacteria, colloids, suspended solids and microorganisms etc. are rejected in the membrane tank.
Applications
● Purification of surface water;
● Reuse of heavy metal waste water;
● Pretreatment of RO.
