ABSTRACT:
The method of the present invention comprises introducing a contaminated fluid mixture containing solids, liquid and contaminating fluid into a preliminary separator to separate the contaminating fluid from the principal liquid and solids; tangentially introducing the contaminated fluid mixture into a vertical cylindrical vessel in a circular motion to further separate the contaminating fluid from the principal liquid and solids; introducing air into the contaminated fluid mixture to further separate the contaminating fluid from the liquid and solids; maintaining the circular flow of the contaminated fluid mixture within the vessel to separate the fluid into contaminating fluid, clean liquid and solid contaminants; collecting the contaminating fluid in a reservoir; removing the contaminating fluid from the reservoir; and, discharging the clean liquid from the vessel.
