The Moving Bed Biofilm Reactor (MBBR) is a sophisticated version of Fixed Film Bio Reactors, which include Rotating Bio Reactors (RBC) and Surface Area Fixed Filmed Technology (SAFF). It is distinguished by the particular feature of its carrier medium floating freely in the sewage or effluent. MBBR technology involves the mixing motion of thousands of polyethylene biofilm carriers in an aerated wastewater treatment basin. The reactor is composed of a tank containing floating but submerged plastic media, usually with a specific gravity of less than 1.0 and consisting of HDPE, polyethylene, or polypropylene. These plastic carriers have a large surface area, which encourages significant bacterial growth. The biomass forms a thin film that is between 50 and 300 microns thick. By offering a covered surface area for the growth of both autotrophic and heterotrophic bacteria, each bio carrier increases productivity.

High-rate biodegradation is achieved by this dense bacterial population, assuring system dependability, simplicity of operation, and efficiency. In order to remove BOD, medium- or coarse-sized bubble diffusers at the bottom of the tank must maintain a dissolved oxygen concentration of at least 2.5–3 mg/L; nitrification requires even higher concentrations. While a clarifier or Dissolved Air Flotation (DAF) unit downstream removes biomass and solids from the wastewater, screens on the downstream walls keep the media contained within the tank. Notably, this technique is efficient and self-sufficient because it doesn't require recycling of sludge.
