APPARATUS AND PROCESS TO SEPARATE AND REMOVE EXTRANEOUS MATTER FROM A LIQUID STREAM

摘要

Waste water contaminants are treated and/or removed in a process and a separator that incorporates a hydrocyclone 66, a constrictive collection passageway 80, 88 above the hydrocyclone for lighter materials which are removed from the surface 92 of the water by a skimmer 112 that effectively entraps and removes 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.
