Abstract
A settling tank for resolving a mixture of oil, water, and solids from an oil and solids-in-water influent includes two inclined and parallel baffles about which the influent water successively passes. Each baffle preferably has parallel V-shaped grooves in the under surface thereof for entrapping, guiding, and coalescing the oil droplets into large globs for channeling and passing through the openings between the baffles and the tank wall for rising to the surface for draw off. The clear water outlet is positioned on a horizontal plane intermediate horizontal planes through the low forward end of the upper baffle and the high rear end to ensure delivery of an oil-free and solids-free water. An upper oil outlet ensures delivery of a solids-free and water-free oil from the settling tank. A new method for assembling a settling tank is disclosed.
