Filter media for
MBBR Wastewater Treatment
Moving bed biofilm reactors (MBBRs) are an advanced wastewater treatment process used for secondary and tertiary stages of biological treatment. This process uses a suspended buoyant media, usually made of polypropylene (PP) or high density polyethylene (HDPE) with density close to water density (to allow the media to mix with the wastewater). The plastic media is mixed with the wastewater and kept suspended by the help of mechanical or aeration systems.
Our high surface area filter media allows higher biomass retention within the MBBR process, thus increasing the process performance efficiency to remove pollutants. MBBRs are used for organic compounds removal, nitrification and denitrification. MBBR systems can be installed in new plants and in existing plants, increasing capacity and nutrient removal without requiring additional tanks, which minimises upgrade costs and the project duration, as well as eliminating the need for additional space.
What benefits do our filter media bring to IFAS treatment processes?
- High surface area to increase SRT and biomass concentration for improved BOD₅ removal and nitrification (>80%)
- Large open area to prevent media blockage by fast-growing aerobic heterotrophic biofilms under high load conditions
- Improved oxygen mass transfer efficiency to reduce energy consumption and carbon footprint
- Cost effective retrofitting into existing plant to upgrade effluent quality and increase treatment capacity
- Durability and rugged with density close to water
- Decreased biofilm shear to minimise biomass detachment
- Low sensitivity to shock loads and temperature changes
- Flexibility for different IFAS configurations to achieve high quality effluent
