Abstract:

A chain and flight mechanism for use in a clarifier tank or other fluid treatment tank includes a skimmer mechanism having a three dimensional configuration and an interior space for collecting floating debris and scum which floats on the water in the tank. The skimmer mechanism is attached to the flight of the chain and flight mechanism by hinge means which allows the skimmer mechanism to move relative to the flight. The fluid treatment tank further includes a self-adjustable scum trough which is capable of moving up and down in the tank responsive to varying water levels.
