Abstract. The paper deals with the control of a wastewater treatment plant designed for a 250,000 inhabitants city. In order to developed different control strategies a specific influent was defined. It is the influent from BSM1 calibrated according to the real data of the wastewaters collected from the wastewater treatment plant.
The wastewater treatment process generates an average amount of primary and secondary sludge equal to about 300–350 m 3 /h (with an average TS content of 1%) which is sent to the sludge treatment units. In addition to carbon and nitrogen removal, chemical phosphorus removal is achieved by dosing ferric chloride solution ...
