comparative assessments of effluent reuse in industrial wastewater plants with energy approach

چکیده
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. other plants used the effluent for agricultural purposes or discharging it to near lands for feeding ground water resources and etc. also, average monthly costs of electrical energy consumption per cubic meter of influent of those plants were investigated. iwwtps were categorized to 5 groups of flow under 250, 250 to 500, 500 to 750, 750 to 1000 and more than 1000 m3/day. finally, it was concluded that larger iwwtps consume more electrical energy per cubic meter influent in comparison with smaller iwwtps. it was concluded that according to the total costs in iwwtps, necessity of effluent reuse should be more considered.
