ABSTRACT:
A method for clarifying a contaminated fluid in a main separator vessel having therein a cyclonic flow chamber. A spiral preliminary spinner introduces the contaminated fluid to be separated in a stratified condition into the cyclonic flow chamber by a tangential inlet so as to establish a swirling body of fluid; the cyclonic flow chamber has concentric shells positioned below the tangential inlet 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 chamber and the wall of the separator vessel wherein water and oil are separated by aeration provided by eductors; a vertical outlet port discharges separated oil and gas from the upper portion of the cyclonic flow chamber to a fluid flow zone wherein oil and gas are separated. The separated water, oil, gas and solids are removed through discharge ports.
