Apparatus and process to separate and remove extraneous matter from a liquid stream

摘要

Waste water contaminents are treated and/or removed in a process and a separator that incorporates a hydrocyclone, a constrictive collection passageway for lighter materials to be removed from the water by a skimmer and skimmer ramp that effectively entrap and remove floatable contaminents while clarified water is removed from the separator at a point in the lower portion of the separator below the hydrocyclone after being aerated with recycled and aerated clarified water above the removal level in the separator vessel.
