Abstract
Abstract This invention relates to water pollution control and concerns a system for removing dispersed oil from water by contacting the oily water with sulfur to cause the oil to coalesce or agglomerate. This invention concerns a horizontal vessel containing a sulfur media through which the oily water flows. The sulfur media presents an area of solid phase sulfur to coalesce the dispersed oil.
