Quality assessment of treated wastewater to be reused in agriculture abstract

In this study, the quality of a treated wastewater for agricultural and irrigation purposes wasinvestigated. 39 quality parameters were investigated at the entrance of an effluent channel to the destinationplain in monthly time intervals during a year. The aim of this study was drawing an analogy between analysesresults and the latest standards in the world (nationwide and internationally), the agricultural and irrigationusage indexes and the Wilcox diagram. The results showed that some parameters such as turbidity, totalsuspended solids, electrical conductivity, sodium, detergents, total coliform and focal coliform, ammonium,residual sodium carbonate, the Kelly’s Ratio and the Wilcox diagram were exceeding the permissible limitand are not suitable for agriculture and irrigation. It was found that the aquifers in the study area werepolluted by natural salinity and geogenic source. As a result, application of the treated wastewater from Qomfor agriculture and irrigation purposes needs to be revised and monitored. An action plan is also needed tomanage a huge source of water and to avoid further environmental and health risks.
