Abstract

 
Background and Objectives: Petrochemical wastewater contains some kinds of toxic substances but if the effluent is treated properly, its reuse will be possible. This study aimed to evaluate the efficiency of wastewater treatment of Shazand Petrochemical Corporation and feasibility of its effluent reuse in green space irrigation and cooling towers.
Materials and Methods: In this descriptive study, the results of tests conducted by the laboratory of Shazand Petrochemical Corporation in 2016 were evaluated and analyzed, and then the feasibility of its effluent reuse in irrigation of green spaces and cooling towers was investigated. So the amount of chemical oxygen demand (COD), total suspended solid (TSS), Fecal Coliform, Total Coliform, turbidity and free chlorine in effluent of pond chlorination and also the amount of silica, alkalinity, calcium hardness, sulphate, COD, electrical conductivity and iron in the effluent of reverse electrodialysis unit were  measured.
Results: The results showed the maximum efficiency of wastewater treatment in the removal of COD was 98 percent. The amount of parameters in the effluent of chlorination pond was in accordance with the environmental standards for irrigation of green spaces and treated wastewater in the electrodialysis unit that with having maximum 0.12 mg/L iron, 126 mg/L sulfate ,and electrical conductivity 695 ϻs/cm was suitable for use in cooling towers.
Conclusion: The results of this study demonstrate that the effluent of chlorination pond can  be used for irrigation of green space and also the treated wastewater in reverse electrodialysis unit can  be used in cooling towers.

Water Reclamation and Reuse: with the Emphasis on the 7th Development Plan (Planning to Access Other Waters and Recycling Industrial Water and Effluent)

Abstract
Today, wastewater reclamation and reuse for different applications is considered as a suitable and economically attractive approach to deal with the main issue of water scarcity. Water reclamation includes wastewater treatment or processing in order to make it suitable for reuse with the reliability of treatment and compliance with water quality criteria. Water reuse is defined as the use of treated wastewater for useful purposes. Health and environmental concerns are primary issues in the implementation of water reuse, so the focus should be on developing approaches that provide sufficient assurance that water quality requirements are consistently met. Considering the importance of water reclamation and reuse, in this article, some methods of water reclamation, the successful experience of water reclamation in Singapore, and a proposed solution for water reclamation and reuse in our country, Iran, have been discussed.
