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.


● Purification of surface water;

● Reuse of heavy metal waste water;

● Pretreatment of RO.

Filtration Performance

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.

Item Limit Remark
