Abstract:
1. A method of separating two distinct and different fluids one lighter in specific gravity than the other able to meet the overboard discharge requirements of the U.S. government, comprising the following steps: (a) providing a vessel, having a primary separation chamber; (b) separating fluids in the vessel to allow for free and suspended solids along with free oil, gas, and grease to be removed in the primary separation chamber; (c) including an induced gas flotation process which provides a finely dispersed bubble in the liquid to accelerate the lift necessary for separation of fine oil droplets, emulsified oil droplets, and suspended solids, for creating a clockwise rotation in the flotation portion of the vessel as a method to move the separated oil to a spillover point on the flotation cell side of the process; and (d) utilizing multiple nozzles on either side of the vessel, so that the flow can be reversed from left to right or right to left depending on the placement of the vessel and existing piping.
