Apparatus for water treatment
Abstract
Abstract A high-output arrangement for water treatment combining in a single housing a number of spaces for coagulation and homogenization, spaces where a perfectly fluidized sludge blanket is maintained, sedimentation spaces and high-rate filter spaces. The spaces for the fluidized sludge blanket have bottoms formed by downwardly converging walls extending over the entire width of the housing and alternately forming roof-shaped tops of homogenizing spaces and of sedimentation spaces as well as the bottoms for the sludge blanket spaces above them. Filter spaces are provided below the homogenizing spaces, separated therefrom by horizontal walls composed of adjacent beams with first channels provided with openings into the sedimentation spaces and connected with the drain, and second channels provided with openings into the filter spaces and connected to collecting means for clear water. The homogenizing space is provided with agitator means, and raw water with a coagulation agent is supplied into said space.
