Evaluation of Efficiency and Biodegradability of Lubricant Oil Treated by Sequencing Batch Reactor (SBR)
Boonchai Wichitsathian and Watcharapol Wonglertarak
Abstract—Oily wastewater is one of the most concerned
pollution sources due to its consisting of toxic substances such as
phenols, petroleum hydrocarbons, and polyaromatic
hydrocarbons. Those substances are also inhibitory to plant and
animal growth as well as mutagenic and carcinogenic to human
being. Such kind of wastewater is mainly originated from crude
oil production, oil refinery, petrochemical industry, lubricant
and car washing. The purpose of this study was to investigate
the effect of lubricant oil concentration normally used in a gas
station on the performance of SBR. The experiment was
performed by varying concentration of lubricant oil from 50
to500 mg/L in SBR with HRT 24 hrs. The results indicated that
the effective removal of COD was in the range of 84-87%. The
oil removal efficiency was found to be in the range of 51-82%.
Considering, effluent of SBR system at HRT 24 hours with the
Readily 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 Readily
biodegradable was to increases.
Index Terms—Oily wastewater, COD fractionations, sequencing batch reactor (SBR).
