Popis: Background & objectives: Build wastewater treatment plants alone will not resolve environmental concerns. But, for achieve optimal environmental standards, the performance of the treatment plants must be constantly monitored and evaluated. The purpose of this study was to feasibility of reuse of output effluent wastewater treatment plant of Ardakan. Materials and Methods: This was a descriptive cross-sectional study. During a 6-month period from April 2019 to September 2019, 48 input and output samples were collected. The parameters studied included COD, BOD5, TSS, total coliform and fecal coliform. Which were measured according to the methods outlined in the Standard Method Book for Water and Wastewater Testing. Finally, the results were analyzed by statistical tests. Results: The results showed that, the mean COD, BOD5, TSS, Fecal coliform and Total coliform at the output were 14.36, 4.56, 2.6 mg/L, 41 MPN/100 mL and 11.2 MPN/100 mL, respectively. Also removal efficiency for COD, BOD5 and TSS, total coliform and fecal coliform were 96.27, 96.81, 98.84, 99.99 and 99.99 Percentage, respectively. Conclusions: The results showed that wastewater treatment plant Ardakan resulted in a significant reduction of organic matter and microbial contamination and was in good condition. And complies with standards in the reuse of wastewater for agricultural use, discharge into surface water and discharge to sorbent wells. Document Type: Research article
