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 when backwashing, meanwhile has good permeable rate, mechanical performance, chemical resistance and pollution resistance. ID & OD of reinforced hollow fiber membrane are 1.0mm and 2.2mm respectively, filtration precision is 0.1 micron. Filtration mode 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 ultra filtration membrane in different types of water:

Using Conditions

Appropriate pretreatments must be taken when raw water contains a lot of impurities and coarse particles, or oil and grease account for a large proportion in the water. Defoamer should be added when necessary to remove foam in membrane tank, please use alcohol defoamer which is not   easy to foul.
