in this research, industrial wastewater treatment plants (iwwtps) were investigated and categorized by effluent applications and electrical energy cost. for the purpose of this research, 51 plants were assessed and results indicate that 17 plants discharged the effluent directly to the surface water that most of them are located in north of iran, 24 plants used the effluent for irrigation. othe...

In this study, the energy consumption of Nasirabad Industrial Park (NIP) treatment plant was evaluated. A combination of up-flow anaerobic baffled reactor (UABR) and aerobic integrated fixed-bed activated sludge (IFAS) processes were employed in NIP. To find out the average electrical energy use per m3 influent wastewater, the rate of energy usage of the plant was calculated by data ...
