ABSTRACT:
An apparatus and method for clarifying a contaminated fluid comprising a separator vessel having therein a pair of cyclonic flow chambers; preliminary spiral separators introduce the contaminated fluid to be separated into the cyclonic flow chambers by tangential inlets so as to establish a swirling body of fluid in each chamber; the cyclonic flow chambers have a shell positioned below their respective tangential inlets for discharging separated solids to a collection area and separating an oil and water mixture into a fluid flow zone formed by the cyclonic flow chambers and the wall of the separator vessel wherein water and oil are separated by aeration provided by sparging tubes; a vertical outlet port discharges separated oil and gas from the upper portion of the cyclonic flow chambers to a fluid flow zone wherein oil and gas are separated. The separated water, oil, gas and solids are removed through discharge ports.
