Abstract |
The current quantity of wastes in refinery effluent pertinent to water pollution problems of the Niagara River area is investigated as a part of the water pollution abatement program by the N.Y. Water Pollution Control Board. Wastes from the refinery are segregated and discharged to the Buffalo River through three oil separators. Chlorides and sediment-oil water emulsion in the crude oil are removed by injecting a caustic demulsifier and treated water into the crude oil, preheating, and settling. Water containing 4 to 5 ppm of oil is rejected to waste. Data indicates a significant reduction in quantity of oil discharged; however, oil films on the river indicate greater than desirable quantities of oil continue to enter the river from some source. |
