Moving bed biofilm reactor (MBBR) is a type of wastewater treatment process that was first invented by Professor Hallvard Ødegaard at the Norwegian University of Science and Technology in the late 1980s.[1] The process takes place in an aeration tank with activated sludge and uses floating, recycled plastic carriers that a biofilm can grow on. The compact size and cheap wastewater treatment costs offer many advantages for the system. The main objective of using MBBR is water reuse and nutrient removal or recovery. In theory, wastewater will be no longer considered waste, it can be considered a resource.
Due to early issues with biofilm reactors, like hydraulic instability and uneven biofilm distribution, moving bed biofilm technology was developed.
The MBBR system consists of an aeration tank (similar to an activated sludge tank) with special plastic carriers that provide a surface where a biofilm can grow. There is a wide variety of plastic carriers used in these systems. These carriers vary in surface area and in shape, each offering different advantages and disadvantages.
The surface area plays a very important role in biofilm formation. Free-floating carriers allow biofilms to form on the surface, therefore a large internal surface area is crucial for contact with water, air, bacteria, and nutrients. The carriers will be mixed in the tank by the aeration system and thus will have good contact between the substrate in the influent wastewater and the biomass on the carriers
The most preferable material is currently high-density polyethylene (HDPE) due to its plasticity, density, and durability.
To achieve a higher concentration of biomass in the bioreactors, hybrid MBBR systems have been used where suspended and attached biomass co-exist contributing both to biological processes.
Large specific surface area, more attached microorganisms
No need bracket, easy to fluidize, save energy
Fast and easily to hang membrane, high biological activity
Strong impact resistance, long lifetime
Excellent nitrogen and phosphorus removal effect
Small footprint, simple and flexible operation management
Good hydrophilicity, good treatment effect
Relying on biofilm treatment, reduces the remaining sludge
Today, MBBR technology is used for municipal sewage treatment, industrial wastewater treatment, and decentralized wastewater treatment. This technology has been used in many different industries, some of them being:
The MBBR system is considered a biofilm or biological process, not a chemical or mechanical process. Other conventional biofilm processes for wastewater treatment are called trickling filters, rotating biological contactors (RBC), and biological aerated filters (BAF).
Enhanced Treatment Efficiency: Provides a large surface area for the attachment of microorganisms, improving the treatment of organic matter and pollutants.
Robust and Durable: Made of high-density polyethylene (HDPE), ensuring durability and resistance to degradation.
Flexibility and Scalability: Easily adaptable to different treatment capacities and site-specific requirements.
Minimal Footprint: Compact design requires less space, making it suitable for areas with limited land availability or retrofitting existing facilities.
Resilience to Load Fluctuations: Can handle variations in sewage flow and pollutant load without constant operator intervention.
Reduced Energy and Chemical Requirements: Lower energy demands compared to other treatment technologies, promoting sustainability.
Some other advantages are:
Higher effective sludge retention time (SRT) which is favorable for nitrification
Responds to load fluctuations without operator intervention
Lower sludge production
Less area required
Resilient to toxic shock
Process performance independent of secondary clarifier (due to the fact that there is no sludge return line).
