Pollutants removal from sewage wastewater using palm oil fuel ash

Abstract

Sewage systems are introduced in the country to protect the health of human and environment. In this study, palm oil fuel ash (POFA) were explored as an adsorbent media for the treatment of a sewage waste water. The optimum shaking speed, shaking time, pH and dosage for chemical oxygen demand (COD), ammonia nitrogen, nitrate and phosphorus parameter removal were investigated using the adsorbent media of particle sizes ranging from 2.00mm to 3.15mm. Composition and characteristics of palm oil fuel ash and composite palm oil fuel ash chemical were then determined. Results indicate that sewage concentrations of COD (63.39mg/L), ammonia nitrogen (6.01mg/L), nitrate (0.63mg/L) and phosphorus (0.43mg/L). The optimum conditions for shaking were determined at 200rpm according to the adsorption of COD, ammonia nitrogen, nitrate and phosphorus by the media. Optimum shaking time of 20min for ammonia nitrogen, nitrate phosphorus and COD optimum shaking time is 30min. Optimum pH and dosage was pH6 and 8g/L, respectively.
