Abstract: Wastewater treatment and disposal is a serious issue and need attention for protecting the environment. Over the recent years, flyash has been experimented as an adsorbent for the waste water treatment plants. The abundant availability, high carbon content and adsorption characteristics of flyash lead to application in waste water treatment methods. In this study, experiments were carried out using flyash as adsorbent in domestic sewage water treatment. A filter media was prepared with pebbles, sand and flyash with different thickness, characterized and used for the removal of impurities. The physico-chemical properties of waste water before and after treatment were examined. The experimental results showed significant reduction in the values of BOD from 385 mg/l to 45-55 mg/l, COD from 680 mg/l to 110-150 mg/l, pH from 8.4 to 6.9 and TDS from 715mg/l to 250-300mg/l after treatment. Beneficial effects of flyash utilization as adsorbent was observed for removing various impurities present in wastewater
