Simplified single cell fluid flow apparatus for flota- tion removal of suspended impurities and liquids are provided wherein the method and apparatus are directed to an induced gas liquid coalescer for flotation separation of suspended impuri- ties. The apparatus provides for a separation vessel which can be fabricated to withstand internal pressure requirements experienced in flotation separation devices wherein the apparatus induces maximum gas volumes consistent with optimum mass transfer of gas medium to suspended impurities in the liquid while controlling intercell or vessel chamber turbulence. Such maximum gas induction achieved without turbulence is through the use of microscopic gas bubbles. Such microscopic gas bubbles provide massive surface area with which the suspended impurities adhere and allows for various apparatus utilization. The continuous operation of the clarification separation is also enhanced by utilization of a sensing probe means for detecting high oil con- tent in combination with diversion means for removing oil slugs to skim removal means as a result of reducing the clarified liquid removal from the bottom portion of the separation chamber. Resultant high oil concentration purge is achieved, nullifying contaminated effluent water discharge from the vessel.
