MBBR Carriers Water Treatment 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.
How Does MBBR Work
Moving bed bioreactor (MBBR) includes a water tank of any shape filled with small carrier elements. These elements are specially developed materials with controlled density, so they can be fluidized using aeration equipment. Biofilms will form on the components, and these will move with the wastewater in the reactor. The movement in the reactor is generated by providing aeration in the diffuser located at the bottom of the reactor. The thin biofilm on the element enables bacteria to act on the biodegradable substances in the wastewater and reduce the BOD / COD content in the presence of oxygen in the air for fluidization. The treated water flows through the grid or sieve from the reactor, thereby retaining the MBBR biocarrier in the reactor. The system can be composed of a one-stage or two-stage treatment process according to the specific needs of wastewater.
