The process is initiated when oily wastewater enters the Enviro-Cell™ at the inlet. The inlet cell provides a surge capacity, dampening the incoming flow, allowing the flotation process to properly function. It also provides a buffer for free oil removal and skimming, lowering the oil content of the process before entering the first active cell.The second stage of the flotation process utilizes four (4) active cells allowing for stage separation with each active cell capable of approximately 60% removal of oil with a composite efficiency range of 90-97%.The final stage of the process provides a clearwell or quiescent area for the removal of small oil droplets. The recirculation system uses the Venturi Principle to create minute bubbles, which is the basis of the flotation process. These small bubbles eject at the outlet of each eductor, rise and attach to free oil droplets providing an accelerated buoyancy for their lift. The simplified oil removal process directs the separated oily froth to the adjustable oil weir for removal. The processed water passes through the complete flotation process and exits the vessel for further treatment or discharge.
