ABSTRACT:
A system for purifying water is provided having a series of filtering systems connected in series in a predetermined order along a flow path of the water to be purified. The filtering systems used in the invention include air striping, aeration, gravity separation, inclined plate coalescing separation, diffused air floatation, metallic oil attraction, static solid separation, hydrocarbon adsorption and absorption, chemical flocking, ozone, and coalescing centrifugal separation. The combination and relative order of placement of these filtering system acheives an improved filtering result.
