Describes how, after extensive testing of 4 different treatment techniques, a Hydro Clear rapid sand filter was installed at the Sohio oil refinery in Toledo, Ohio. This filtration system has proven to be more cost-effective than conventional approaches. The system handles the refinery's wastewater flow of 10.3 mgd. With the aid of the polishing filter, readily meets the NPDES permit limitations. The Toledo refinery is a highly integrated petroleum processing complex. It processes 127,000 barrels per day of crude oil, including 40,000 barrels per day of sour crude. Tables give dissolved air flotation performance data; biological system performance data; filter performance data; and refinery waste treatment unit compared with NPDES-BPT limitations. Diagram shows the Sohio refinery wastewater treatment facility. Through a separate backwash treatment system complete control is brought to the suspended solids in the effluent which also tends to control chemical oxygen demand and oil/grease levels.
