Abstract

A separator 252 for immiscible liquids comprises a tank having an inlet, a separation chamber and an outlet chamber 262, with the inlet 12 feeding effluent into the separation chamber 28 at or below a maximum acceptable flow rate. The effluent is separated into a more dense and less dense fractions in the separation chamber 28. The separation chamber 28 is in communication with the outlet chamber 262, where the more dense fraction exits. An outlet 260 for the less dense fraction is in communication with the separation chamber 28 and has a lowermost exit level at which the less dense fluid exits. The more dense fluid cannot rise to the level of the lowermost level, and the height of the less dense fluid is such that it will exit through the outlet as the more dense fluid passes over the weir.
