Abstract
Apparatus for reducing the solids and oil/grease components of a water mixture includes a tank for holding a water mixture for a period during which heavier-than-water components of the water mixture settle to the bottom of the held water mixture and lighter-than-water components rise to the top of the held water mixture. It includes devices for separating solids from liquids in a flow of solids and liquids and for separating oil/grease from water in a flow of oil/grease and water. A first discharge line from the tank adjacent the location of the heavier-than-water components communicates with the device for separating solids from liquids, and a second discharge line from the tank adjacent the location of the lighter-than-water components communicates with the device for separating oil/grease from water. A third discharge line from the tank intermediate the first and second discharge line is provided for the removal of water with reduced solids and oil/grease components.
