Assessment of Quality Parameters in the Effluent and comparing it with Environmental Standards using the Effluent in Green Area Irrigation
The aim of this study was to evaluate the performance of the wastewater treatment system for the re-use of effluent in green area irrigation. In this study, the chemical parameters of BOD, COD, TSS, and pH were tested seasonally from June 2005 to March 2018. The mean value of the indices for BOD, COD, TSS, and pH was obtained 130, 200, 92, and 8, respectively. Comparison of the parameters process with the EPA, FAO, WHO and DOE standards shows that the effluent of wastewater treatment plants is suitable for irrigation of green spaces. However, its application requires management, accurately planning, continuous investigation of the operation of the treatment system, and applying technical and engineering solutions for the treatment system. Using these solutions, it is possible to increase the quality of effluent to the most favorable level of standards of the Iranian Environmental Protection Agency and minimize the environmental and health impacts caused by its use.
