Abstract

Background: Today, in many countries, wastewater treatment plants effluent is an important part of the renewable water resources. In this case, the effluent quality standards are developed and used is important. The aim of this study was to investigate the potential use of wastewater plants effluent Restricted Irrigation. Methods: In this descriptive - analytical study, samples was collected from the Isfahan wastewater treatment plants effluent. Effluent quality parameters; BOD5, COD, pH, calcium, magnesium, sodium, electrical conductivity, sodium absorption ratio absorption %Na, SAR, boron and chloride were analyzed. Results: Average of BOD5 and COD parameters in both plants was same as environmental standards but does not meet EPA standards. Both Wastewater effluent pH values were in the range of 9-6. Boron concentration and sodium adsorption ratio in the north wastewater treatment plant was good, for irrigation. %Na, chloride concentration and EC was inappropriate. In the south wastewater treatment plant, boron and SAR was at the excellent level. Chloride and EC was permissible, and %Na was good. Conclusion: Based on independent sample t test, there was significant deference between Isfahan North and South wastewater treatment plants (p<0.05). There was not seen significant deference between effluent quality and standard level in both treatment plants (p>0.05). With proper operation of treatment plants and use of an appropriate disinfection process, the suitable effluent quality for agricultural purposes is provided.
