Investigation of effectiveness of carbonized rice husk in oily water treatment

Abstract

In this study, agricultural waste, rice husk was used as an adsorbent in the oil pollution management. Thermally treated rice husk, prepared by carbonizing rice husk at 600 °C for 3 hrs, were tested for oil removal from aqueous mixtures. Solution pH, adsorbent dose and mixing time affect the degree of oil removal. COD removal efficiencies of 99% were achieved.
