Control of gaseous volatile organic compounds using a sponge medium based rotating biological contactor

Abstract

Volatile organic compounds VOCs containing toxic air pollutants mainly benzene toluene ethylbenzene and xylene BTEX are generated from paint chemical and petrochemical industries and have a harmful impact on human health and the atmosphere In this research rotating biological contactor RBC has been designed and developed with sponge as a bio support medium for the control of benzene and BTEX at different combinations The performance of RBC at different inlet loading rates ILR an
