Abstract
Many chemicals exist in the petroleum wastewater, whose disposal into the environment can result in environmental pollutions and serious damages to the ecosystem.Since conventional treatment processes are not sufficient to achieve the water quality requirements, advanced treatment processes are required. In this study, Hybrid Membrane Bioreactor (HMBR), Rotating biological contactor with packing (RBCp) coupled with an external membrane, is used for synthetic petroleum wastewater treatment. Biodegradability of chemical oxygen demand (COD) and that of total petroleum hydrocarbon (TPH) were evaluated and compared for different hydraulic retention times (HRTs) and petroleum pollution...
