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. In a preferred embodiment, the water containing the dispersed oil is passed through a bed of granular media presenting a surface area of solid phase sulfur to coalesce the dispersed oil. The coalesced oil is then separated from the water.
