Abstract
Oily wastewater is one of the most concernedpollution sources due to its consisting of toxic substances such asphenols, petroleum hydrocarbons, and polyaromatichydrocarbons. Those substances are also inhibitory to plant andanimal growth as well as mutagenic and carcinogenic to humanbeing. Such kind of wastewater is mainly originated from crudeoil production, oil refinery, petrochemical industry, lubricantand car washing. The purpose of this study was to investigatethe effect of lubricant oil concentration normally used in a gasstation on the performance of SBR. The experiment wasperformed by varying concentration of lubricant oil from 50to500 mg/L in SBR with HRT 24 hrs. The results indicated thatthe effective removal of COD was in the range of 84-87%. Theoil removal efficiency was found to be in the range of 51-82%.Considering, effluent of SBR system at HRT 24 hours with theReadily biodegradable, the value percentage increase of 62.00%,57.79%, 60.54%, 54.53%, 41.79% and 36.03%, respectively,and Slowly biodegradable hydrolysis into Readilybiodegradable was to increases.
