Abstract

Wastewater output has increased considerably as a result of global population growth. Efforts to manage wastewater are expanding globally. Bio-based methods are useful and effective for treating a wide range of wastewaters, especially those from homes. In this research, the gray water stream at Sari Agricultural College in the north of Iran was treated using an anaerobic biological method. The purpose of this study was to determine whether using treated gray water for landscape irrigation was feasible or not. A fine screening pre-treatment system and a septic tank system were created in order to achieve this goal. After the first stage screening of superfluous solid components, anaerobic digestion was carried out for 26 hours at a temperature of between 14 and 16 °C in a 5 m3 septic tank. Treatment method function was revealed by measuring and comparing the pollutant indices with the permissible rates. The obtained data were: BOD 19.5 mg/L, COD 185 mg/L, Suspended Solid (SS) 90 mg/L, Organic Matter (OM) 80 mg/L, NO3 26 mg/L, PO4 6.25 mg/L, Oil and Grease (O&G) 9.3%, pH 5.9-7.1. The permissible rates for these indices are 100, 200, 200, 300, 30, 6.75, 10, and 6.8-7.1, respectively. The treated gray water was allowed to be utilized as irrigation water. After irrigating, the landscape did not face any negative effects. Nonetheless, the high acidity was owing to the detergents in effluent and this was the main reason provides a vast range of microelements leading to poisoning plants in a long period.
