The Prague's wastewater treatment plant includes mechanical and secondary biological treatment with an upgrade of the activated sludge process to partial nitrification and gentrification and gas facility. The plant's capacity (population equivalent) is 1.43 million, the hydraulic is 7.0 m3/s (during rains it is 8.2 m3/s). The main aim is to increase efficiency of sludge removal from the secondary clarifiers after necessary reconstruction. A 3D multiphase mathematical model was used to study possible efficiency improvement while 12 different scenarios (+ the present state) were simulated and compared. Simulation of the clarifiers brings new knowledge of their behaviour. The study has resulted in an optimised design of the secondary clarifiers to be used within reconstruction.
