Abstract
Abstract A process and apparatus for treatment of waste water is provided wherein a waste water clarifier is positioned in a waste water flow channel and having a body assembly with a bow section facing into and extending above the waste water currents, a stern section having a opening below the waste water level to allow waste water to enter the clarifier and, having a rear baffle extending between clarifier side walls and extending downward perpendicularly thereto and a second baffle extending partially between the clarifier side walls and extending downward and perpendicularly thereto, the bottom section having rows of tubular pipes extending at an angle downward therefrom with the pipe openings facing opposite the waste water flow, and an effluent launder fixedly positioned in the bow section.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
A clarifier for removing solids from waste water in a waste water flow channel comprising, (a) a forward section connected to a rear section by side walls, said forward section and side walls rising above said waste water, said rear section having an opening below the waste water level to allow said waste water to enter a cavity formed by the forward section, the rear section and the side walls. (b) a bottom panel attached to said side walls below said waste water level, said bottom panel having rows of vertically inclined panels separated by bottom openings to allow said solids to flow from said cavity back to said channel; (c) an effluent launder attached to said side panels and postioned in said forward section, said launder comprising a trough having means to allow said waste water located in said cavity to enter said through; and, (d) hollow directional tubes connecting with said bottom openings and angularly inclined down from said bottom panel and facing opposite the waste water flow.
