Separator for low discharge applications

摘要

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.
