Flat Bottomed OWS Process Overview
The FB design is most commonly used wherever oils and fuels can come into contact with a low to no solids waste stream.
How the Flat Bottom Oil Water Separator Works
The FB places a volume of corrugated Flopak coalescing media into the waste stream, the tank's flow path brings the oils and solids bearing water to the influent end of the plate pack, it flows horizontally through the pack where oils then encounter the plate surface and are effectively separated from the water, the oil droplets roll up the plate surface begin to coalesce into larger droplets. Then, the larger droplets increased buoyancy pulls the oils away from the surface rising to the water surface.
