SEWAGE TREATMENT PLANT (STP)

Moving Bed Biofilm Reactor (MBBR)

Moving Bed Biofilm Reactor, which is a biological wastewater treatment process used in Sewage Treatment Plants (STPs) to improve the efficiency of removing organic matter, nitrogen, and other contaminants. It is an advanced technology that uses small, specially designed plastic carriers (media) to support the growth of biofilm (microorganisms) for treating wastewater.

Key Advantages of MBBR in STP:

The following steps are involved in basic wastewater treatment:

• Compact Design:MBBR systems require less space compared to traditional biological treatment systems like activated sludge processes because the carriers increase the surface area available for biofilm growth.
• Higher Treatment Efficiency:The use of biofilm carriers ensures high contact between microorganisms and pollutants, leading to more efficient organic matter and nutrient removal, especially in high-strength or variable wastewater conditions.
• Low Maintenance:MBBR systems do not require complex control systems, return sludge systems, or regular cleaning, as is common in other biological systems like activated sludge.
• Flexibility & Scalability:MBBR technology is modular and easy to scale. It can be retrofitted into existing STPs to enhance capacity or improve performance without significant changes to the plant layout. It works well under different load conditions and can treat varying wastewater volumes or pollutant concentrations effectively.
