PE10 / K5 MBBR HDPE Filter Media For Culturing Biofilm In White
Product Description
Moving bed biofilm reactor (MBBR) has built thousands of sewage
(waste) treatment facilities in many countries in the world and
achieved good treatment results. MBBR Process uses the basic
principle of biofilm process, combined with the advantages of
activated sludge process, with suspended packing as the carrier of
microbial growth, through the full fluidization of suspended
packing in the secondary biochemical tank, to achieve efficient
sewage treatment.

Features
1. Simple: the activated sludge tank or anaerobic tank can be
modified into MBBR only by adding certain filler in the aeration
tank;
2. Low transformation cost: 10-70% of the filler is added
(according to the effective volume);
3. High efficiency: the volume load can be increased by 2-4 times,
and the floor area is small;
4. Low energy consumption: small head loss, slightly higher energy
consumption than activated sludge;
5. High stability: MBBR has strong tolerance when temperature
changes, sewage composition changes or sewage toxicity increases.
Application Scope
1. Upgrading of sewage treatment plant;
2. Solve the problem of ammonia nitrogen exceeding the standard;
3. Expansion and reconstruction of sewage treatment plant;
4. The efficiency of anaerobic treatment of high concentration and
refractory organics was improved;
5. High concentration and refractory organic aerobic pretreatment.
