MBR Membrane Module Reinforced PVDF BM-SLMBR-20 Sewage Treatment
● Unique gradient reticular pore structure, high filtering precision and good output quality;
● Unbreakable hollow fibers, 3-layer protective structure, hollow fibers are not easy to fall off, service life can reach 5 years +;
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.
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.
