Plastic MBBR Bio Film Carrier technology employs thousands of polyethylene bio film carriers operating in mixed motion within an aerated waste water treatment basin. Each individual bio carrier increases productivity through providing protected surface area to support the growth of heterotrophic and autotrophic bacteria within its cells. It is this high-density population of bacteria that achieves high-rate bio degradation within the system, while also offering process reliability and ease of operation.
The principle of MBBR process is to use the basic principle of biofilm method, by adding a certain number of suspended carriers to the reactor to improve the biomass and biological species in the reactor, so as to improve the treatment efficiency of the reactor. Because the density of the filler is close to that of water, it is completely mixed with water during aeration, and the growth environment of microorganisms is gas, liquid and solid.
The collision and shearing of the carrier in water make the air bubbles smaller and increase the utilization rate of oxygen. In addition, there are different biological species inside and outside each carrier, with some anaerobes or facultative bacteria growing inside and aerobic bacteria on the outside, so that each carrier is a micro-reactor, so that nitrification and denitrification exist at the same time. As a result, the treatment effect is improved.
