The purpose of this study was to evaluate the toxic effects of various heavy metals on activated sludge process. Different concentrations of Cu(II) (0.5, 1.0, 5.0, and 10.0 mg/l), Ni(II) (5.0, 10.0, 25.0 mg/l), and Cr(VI) (1.0, 5.0, 10.0, 25.0, 50,0 mg/l) were maintained in a laboratory-seale completely mixed activated sludge unit, without recycle, treating simulated wastewater. The feed s...... hiện toàn bộ

To ensure correctly operating control systems, the measurement and control equipment in WWTPs must be mutually consistent. The dynamic simulation of activated sludge systems could offer a suitable tool for designing and optimising control strategies. Ideal or simplified sensor models represent a limiting factor for comparability with field applications. More realistic sensor models are the...... hiện toàn bộ
