Patent GB-2105601-A (GB)
Title: Apparatus and method for clarification of water using combined flotation and filtration processes
Inventor: KROFTA DR MILOS
IPC: C02F1/52
Filed: 1982-07-21
Abstract: Apparatus and a method for removing suspended particles from water in a circular tank having a distribution and flocculation chamber immersed in the tank of water and carried circularly around the tank by a carriage. Flocculating material and inlet water are introduced into the body of water from the moving flocculating chamber at the same rate as clarified water is discharged through a filter substantially covering the bottom of the tank. A majority of particles in the water is collected by flocs in the water and floated to the water surface by air bubble action. The floating sludge is removed by a spiral scoop carried by the carriage. The water is then passed through the bottom filter which removes the remaining flocs completing the clarification of the water for discharge. Apparatus is provided for selectively back washing sections of the filter while the remainder of the filter is in operation.
