If the main treatment is based on the activated sludge (AS) process, then we retrofit upgrade it without extension to advanced advanced activated sludge (AAS) resulting in 2 - 3 times more biosludge (MLSS) in the existing basins to handle 2 - 3 times higher organic loads (BOD, COD, ... as kg/d) at the design F/M (food-to-micro-organisms ratio). This may require additional aeration capacity. Also the clarifiers may need a retrofit upgrade as to handle higher hydraulic (flow rate Q) and solids loads MLSS x (Q + Qr). Of course adequate process automation would be needed as well for best performance.

A routine disluging it can helps, in line with enough drying beds.
