Feasibility of wastewater reuse of Anbaj treatment plant for different usages with an emphasis on artificial recharge of groundwater

All countries are trying to reuse the waste water. In this study, in order to feasibility of wastewater reuse, parameters such as temperature, turbidity, pH, EC, COD, BOD, TSS, TDS, SAR, carbonate, bicarbonate, alkalinity, chloride, nitrate, sodium, ammonia, magnesium, calcium, total difficulty, phosphate, fecal coli in wastewater of Anbaj treatment plant (Shemiranat region) were investigated seasonally between 2010 and 2011 and restrictions on the reuse of different uses were identified. Quality of studied wastewater for agriculture was in accordance with Iranian Environmental standards except in microbial parameters. EC, TDS and bicarbonate has low to average limitations for irrigation. Based on Wilcox diagram, studied wastewater is located at medium stage (C3 S1) considering alkalinity and salinity. The studied waste water has some problems for aquifer artificial recharge considering the ammonia parameter. According to discharge standards for surface waters ammonia and calcium have some constraints. BOD and ammonia couldn’t be used for aquaculture, environment, recreational and wildlife usages. The studied waste water wasn’t appropriate for industrial use and is classified in waters with medium quality by power ministration.
