ABSTRACT:
The invention generally relates to an improved flotation apparatus and process for purifying a stream of effluent by forming a separable, buoyant floc out of waste matter suspended in the effluent. The improved process and apparatus utilizes a tank for containing an effluent, a skimming means for skimming the buoyant floc out of the tank, and a floc barrier and current diverting means including an inclined, buoyant top wall which is pivotally mounted on the sides of the flotation tank, and a bottom wall having a top edge which is adjacent to the bottom edge of the top wall. The upper portion of the buoyant top wall prevents floc from straying from the floc accumulation region of the tank over to the outlet region of the tank, while the lower portion of the top wall, working in conjunction with the bottom wall, diverts fluid currents which tend to float floc over to the outlet region of the tank. The buoyant top wall pivotally coacts with the skimming paddle of the skimming means to trap floc into the floc accumulation region of the tank.
