ABSTRACT:
Improved skimmer apparatus for use in dissolved air floatation basins employed in water purification and waste water treatment plants is provided. The invention includes centrally positioned, longitudinal guide rails affixed to the basin and two or more interconnected reciprocating carriages, each carriage having a skimmer blade affixed thereto, the carriages being moveably mounted on the rails. At the effluent end of the basin is an upwardly shaped ramp, and the carriage nearest in proximity to the ramp has a ramp profile duplicating mechanism pivotally mounted to it. The carriages with attached skimmer blades are advanced at desired time and distance intervals advancing the sludge from the influent end of the basin toward the effluent end of the basin and the ramp, until the carriage having the ramp profile duplicating mechanism advances to and upwardly upon the ramp, the skimmer blade affixed thereto raising the sludge above the liquid level thereat, thereby removing excess liquid and depositing the sludge into a hopper for disposal. The skimming blades are then raised above the liquid/sludge surface and returned to the place of beginning and the skimming cycle is repeated.
