Abstract
The wastewater produced as a result of trucking station activities has some major characteristics such as high COD (26,880 mg/1-42,925 mg/1) and BOD (12,278 mg/1-7,265 mg/1), high COD to BOD ratio (3.49-3.69), high pH range (3.72-11.7), and high grease content (480 mg/1-1,960 mg/1). Therefore, prior to any treatment, it is important to provide some sort of pre-treatment for pH adjustment and grease/oil removal.
The present laboratory investigation has indicated that successful treatment and purification of the subject wastewater is possible using two-phase anaerobic digestion system followed by rotating biological contactor. More than 90% of both COD and BOD was removed by the anaerobic digestion system having a retention time of 0.67 days and 4.03 days in the acid digester and the methane digester, respectively. The concentration of BOD could further be reduced down to 157 mg/i when the rotating biological contactor was operated at a hydraulic retention time equal to 2.86 days. Both RBC and anaerobic digestion system can be theoretically described by the Monod type of kinetic expressions.
