The MBBR is a highly effective biological treatment process for the removal of organic matter, nitrification and denitrification. The MBBR system consists of an activated sludge aeration system where the sludge is collected on plastic media. These media have an internal large surface for optimal contact to water, bacteria and air. The bacteria grow on the internal surface of the media. The bacteria break down the organic matter from the wastewater. The aeration system keeps the media with activated sludge in motion. The excess sludge will come separate from the media and will flow with the treated water towards the final treatment.

Basin: The MBBR process takes place in a basin/tank, also known as a bio-reactor or as an aeration tank. The size of this bio-reactor depends on the filtration needs of a particular plant. Influent enters this bio-reactor for treatment.  MBBR aeration tanks are open at the top or vented adequately, exposing the water to the open air, which makes this an aerobic process of filtration.

Media: The basin is full of thousands of small plastic chips, called media or carriers. These media may occupy as much as 40 to 65% of the tank. Their design maximizes the surface area they provide for biofilm to grow on them. Many carriers resemble  wheel-shaped, pucks They mirror the density of water, allowing them to mix throughout the fluid, rather than floating or sinking.

Aeration grid: Another thing that helps the media move effectively throughout the tank is an aeration grid. This device is essentially like a fan located at the bottom of the reactor tank. The aeration grid helps keep carriers in motion so they can come into contact with all the waste present and efficiently decompose it, and introduces more oxygen into the tank.

Sieve: The mesh material allows water to pass through, but keeps the plastic carriers inside the bio-reactor.
