Moving Bed Biofilm Reactor (MBBR)


The Moving Bed Biofilm Reactor (MBBR) is an advanced technology used for wastewater treatment that has gained considerable attention in recent years. It offers a highly efficient and cost-effective solution for removing organic matter, nitrogen, and other pollutants from wastewater streams. The MBBR process utilises specially designed carriers to create a suspended biofilm, which provides a large surface area for the growth of microorganisms that degrade contaminants.

The MBBR technology is commonly used in municipal wastewater treatment plants to enhance the removal of organic matter and nitrogen. MBBR systems can be integrated into existing treatment processes, providing additional capacity and improving the overall treatment efficiency. The technology effectively reduces domestic wastewater’s carbonaceous and nitrogenous load, ensuring compliance with stringent effluent discharge standards.

Industrial wastewater treatment is another significant application of MBBR technology. It offers a versatile solution for treating effluents from food and beverage, chemical manufacturing, and pulp and paper industries. MBBR systems can effectively remove organic pollutants, oils, fats, and other contaminants specific to each industry, resulting in cleaner and safer wastewater before discharge or reuse.


High treatment efficiency: The suspended biofilm in the MBBR process provides a large surface area for microbial growth, resulting in enhanced treatment efficiency and organic matter removal. The technology effectively reduces wastewater's Biochemical Oxygen Demand (BOD) and ammonia levels.

Robust and stable operation: The biofilm's diverse microbial community enhances process stability and resilience to variations in influent characteristics and hydraulic loads. The biofilm carriers protect microorganisms, reducing the risk of washout or sludge bulking.

Compact design and flexibility: MBBR systems have a small footprint and can be easily integrated into existing treatment plants or used as standalone units. The modular design allows for easy expansion and modification to meet changing treatment requirements.

Reduced sludge production: Compared to conventional activated sludge processes, MBBR technology produces less excess sludge, resulting in lower disposal and handling costs.

Tolerance to shock loads: The biofilm carriers provide a buffer against shock loads and hydraulic variations, allowing the system to withstand sudden changes in wastewater flow. and composition
