ABSTRACT:
Waste water containing pollutants such as suspended solids and emulsified oil is pumped continuously through a self-contained separating or polishing system utilizing a simplified plug-in module to remove the pollutants. The suspended solids are removed by mechanical filtration and the emulsified oil is separated by coalescing oil into floatable droplets which can be skimmed from a water surface and withdrawn for external accumulation. The treated waste water may be returned for further use or pumped to other facilities for further treatment.
