Moving bed biofilm reactor (MBBR) is a biological technology used for wastewater treatment process suitable for municipal and industrial application. Another common name is moving bed film reactor. It was invented in the 1980s. MBBR offer an economical solution for wastewater treatment. STP MBBR technology is the use of a moving bed biofilm reactor in sewage treatment plants.

Biofilm process, The trickling filter can be reliable and stable but does suffer from one serious drawback; it easily becomes clogged and septic even under moderate loading conditions. In the MBBR biofilm technology the biofilm grows protected within engineered plastic carriers, which are carefully designed with high internal surface area. These biofilm carriers are suspended and thoroughly mixed throughout the water phase. With this technology it is possible to handle extremely high loading conditions without any problems of clogging, and treat industrial and municipal wastewater on a relatively small footprint.

① Improving standards and quality for the wastewater upgrading and reforming project;
② Carrier of wastewater treatment MBBR and biological aerated filter;
③ Biochemical treatment of water reuse,
④ New projects saving investment and land occupation planning;
⑤ River regulation for nitrogen and phosphorus removal;
⑥ Aquaculture for ammonia nitrogen removal and water purification;
⑦ Biofilm packing for biological deodorization tower;
⑧ Application industry: municipal, electric power, pharmaceutical, chemical, electroplating, metallurgy, medical treatment, machinery, paper making, printing and dyeing, food processing, aquaculture, etc;
⑨ With the continuous improvement of products and deepening of application, the application field of PE bio-suspended filler will be more and more broad.
