MCR Membrane Module Reinforced PVDF BM-SLMCR-30 Replacing Project

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.

Using Conditions

Proper pretreatments must be set when raw water contains a lot of impurities/coarse particles or large proportion of grease. Defoamer must be used to remove foams in membrane tank when necessary, please use alcoholic defoamer which is not easy to scale.
