Event Description:Within a single tank, the AGS system creates proper conditions to reliably maintain a stable granule, without the need of carriers. Due to the layered microbial community within the granule structure, simultaneous processes take place in the granular biomass, including EBPR, and simultaneous nitrification/denitrification. Extracellular polymeric substance (EPS) biopolymer, produced by bacteria, forms the backbone of the granule. These granules enable the system to better withstand adverse conditions compared to conventional systems.
Due to the characteristics of the granular biomass and enhanced settling properties (SVI at 30-50 mL/g), the system is typically designed for 8 g/L of MLSS. Based on this and the fact that all processes occur in a single tank, the AGS system reduces footprint up to 75% and provides up to 50% energy savings compared to activated sludge systems; in addition to savings in chemical consumption when low level effluent nutrients are required. AGS is an ideal technology for plants looking to increase capacity, retrofit or upgrade, expand with limited footprint, and enhance biological nutrient removal.
