Moving Bed Biofilm Reactor
Moving bed biofilm reactor (MBBR) is an effective biological treatment process that combines biofilm media and activated sludge process. The treatment process is capable of operating at high volume loads and can be aerobic and/or anaerobic. Plastic carriers covered in biofilms are utilized for the decomposition of waste. In addition to the treatment of organic waste, MBBR can also be an effective method for nitrification and denitrification. MBBR is usually a part of multi-step system for wastewater treatment involving grit removal and disinfection steps as with other biological treatment processes.
MBBR Design Components
🧱 Key Components of MBBR Systems
Basin (Reactor/Aeration Tank) The basin, also known as a reactor or aeration tank, is the core vessel where the Moving Bed Biofilm Reactor (MBBR) process occurs. Its dimensions are determined by the specific filtration requirements of the plant. Typically open at the top, the design supports an aerobic filtration environment, facilitating efficient biological activity.
Media (Carriers) Inside the basin, a substantial volume—50–70%—is filled with plastic chips referred to as media or carriers. These chips are engineered to match the density of water, ensuring uniform dispersion throughout the wastewater. As biofilm forms on their surface, the media create a high-surface-area environment essential for effective microbial activity and enhanced pollutant breakdown.
Aeration Grid Positioned at the bottom of the reactor, the aeration grid comprises fans or diffusers that ensure consistent media movement within the fluid. It also facilitates the introduction of oxygen, supporting aerobic conditions and maximizing biological treatment efficiency.
Sieve Assembly A sieve made of mesh material is installed to retain the plastic media within the basin while permitting the treated water to exit freely. This component is crucial for maintaining media integrity and ensuring seamless flow dynamics.
