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.
Apparatus as defined in claim 1; and further comprising hydraulic resistance means provided at the respective first slot means for equalizing hydraulic resistance at opposite sides of said first slot means.
Claim 2
Dependent Claim
59 words
An apparatus as defined in claim 1; further comprising substantially horizontal wall portions extending between and separating the upper regions and the lower regions of the respective filtration zones from one another; and drain means communicating with said upper regions in the vicinity of said horizontal wall portions for evacuating sediment from said upper regions of said filtration zones.
Claim 3
Dependent Claim
44 words
Apparatus as defined in claim 1, said agitating means comprising at least one at least substantially horizontal shaft arranged in each of coagulating zones extending longitudinally of the same, turbulence-creating means affixed to said shaft projecting therefrom, and rotating means for rotating said shaft.
Claim 4
Dependent Claim
32 words
Apparatus as defined in claim 4, wherein said shaft is hollow and provided with a plurality of longitudinally spaced openings, and wherein said supply means communicates with the interior of said shaft.
Claim 5
Dependent Claim

Apparatus as defined in claim 2, wherein said resistance means comprises baffle means.
Claim 7
Dependent Claim
35 words
Apparatus as defined in claim 3, said horizontal wall portions being provided with first channels communicating with said upper regions and with said drain means, and with second channels communicating with said second collecting means.
Claim 8
Dependent Claim
11 words
Apparatus as defined in claim 8, said channels being interior channels.
