IMPROVING COMBINED SEWER OVERFLOW AND TREATMENT PLANT PERFORMANCE BY REAL-TIME CONTROL OPERATION

摘要

In recent years, urban stormwater discharges have been recognised as one of the main causes of the environmental problems of receiving water bodies. During rain events, in fact, large amounts of water and pollutants are directly discharged through combined sewer overflow (CSO) devices into the receiving waters without any treatment [1, 2, 3, 4]. In addition, storm flow peaks and pollutant shock loads can arrive at the treatment plant (TP) reducing its efficiency or causing malfunctioning.
