Product Overview

MBR is a combination of membrane technology and bio-chemical  reaction  in water treatment. MBR filter the sewage in bio-chemical tank with membrane so that sludge and water are separated. On one hand, membrane rejects microorganisms in the tank, which greatly increase the concentration of activated sludge to a high level, thus the bio-chemical reaction of sewage degradation processes more rapidly and thoroughly. On the other hand, water output is clear and of high quality because of high precision of membrane.

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 0.1 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.


●Treatment, recycle and reuse of industrial waste water;

●Treatment of refuse leachate;

●Upgrade and reuse of municipal sewage.

Filtration Performance

Below  filtration  effects  are  proved  according  to  the  use  of  modified  PVDF hollow fiber ultrafiltration membrane in different types of water:

No. Item outlet water index
1 TSS ≤1mg/L
2 Turbidity ≤1
3 CODcr Removal rate depends on the bio-chemical performance & designed sludge concentration
4 NH3-H (Instant removal rate ≤30% without bio-chemical)

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.
