Abstract

Given the shortages of available water, especially for agricultural purposes, waste water reuse prevents contamination of water as well as partially solving the current water shortage problems. The aim of this study is to determine the quality of wastewater effluent from the Wastewater Treatment Plants (WWTP) at Kashan University of Medical Sciences (KAUMS) using the correlation between Total Suspended Solids (TSS) with Total Coliform (TC), and Fecal Coliform (FC) for agricultural use. All samples were taken from the sanitary WWTP effluent at KAUMS. Standard methods was used for physiochemical- and biological analysis of TSS, TC and FC. The obtained results indicated that the value of R2 between TSS–FC and TSS– TC, regressions were; 0.78 and 0.79, respectively, P-value was found less than 0.001 for the regressions in both cases, also. Therefore values of TC and FC could be estimated based on TSS parameter. A significant correlation between TSS, TC and FC parameters was observed in WWTP effluent, in accordance with obtained results of the current study.
