Abstract

Reusing of treated waste water could be considered as a solution to overcome the water shortage problem. The aim of this study is to evaluate the feasibility of reusing waste water treatment plant’s effluent of Kermanshah’s Rozhin Tak tomato paste factory for agricultural irrigation. This study conducted cross-sectional and measure some parameters such as pH, COD, TSS, TDS, and DO, Nitrite, Nitrate, Ammoniac, Phosphate and turbidity and finally coordinated them with environmental standard in order to reuse them in agricultural irrigation. The results showed that the effluent’s average parameters of DO and TSS in all months of the year (except July, August, September and October) and the turbidity rate in all the year (except June) is lower than reuse standard in agriculture (P<0.05). Also the effluent’s average level of DO in all months of the year (except July, August, September and October) is higher than reuse standard in agriculture (P<0.05). The pH level of effluent in all months of the year was consistent with reuse standard in agricultural irrigation. The results of the evaluation showed that in some months which effluents were used for irrigation, they weren’t consistent with standards. Therefore, improvement of the present treatment system for achieving to an effluent standard is necessary. © 2015, International Journal of Pharmacy and Technology. All rights Reserved.
