The AGAR™ fixed film activated sludge process is an innovative biological treatment process that uses thousands of special carriers designed to create an enormous total surface area for biofilm growth – enhancing your wastewater treatment process without expanding your footprint.
Fixed Film Activated Sludge Process Configurations and Applications
Process for Nitrification Denitrification
The AGAR® IFAS process configuration combines the attached biofilm process with the activated sludge
process. This configuration is specifically designed for:
- Adding nitrogen removal to existing activated sludge plants
- Increasing WWTP capacity and improving effluent quality
Process for Biological Nutrient Removal
An AGAR® fixed film sludge process configuration for biological nutrient removal (BNR) includes anaerobic, anoxic and aerobic process stages. This design is used for:
- Retrofitting existing plants for biological Nitrogen and Phosphorus removal
- Design of new plants for compliance with nutrient removal requirements
Process for BOD Removal
The AGAR® fixed film process can be configured for achieving intensive BOD removal in a very short Hydraulic Retention Time (HRT). This solution is best suited for:
- Increasing the BOD removal capacity of an existing plant
- Compact plants for BOD removal
