Abstract
1290062 Bioflocculation CESKOSLOVENSKA AKADEMIE VED 9 Dec 1970 [11 Dec 1969] 58472/70 Heading C1C A treatment of polluted liquids consists of subjecting the liquid to bioflocculation in a closed space, withdrawing part of the liquid with the thus created suspension and allowing this to sediment by gravity in an inclined sedimentation channel, taking a first stream of liquid with a diluted suspension from an external part of the channel for filtering through a fluidized sludge blanket, directing a second stream of concentrated suspension by gravity from an internal part of the channel back into the bioflocculation space and withdrawing liquid from the sludge blanket. The treatment may be carried out in the apparatus of Fig. 1 wherein the polluted liquid enters the bioflocculation space A at the supply means 4 and has dispersed therein, an oxidizing gas injected at the jet 5. A mechanical agitator 10 imparts a helicoidal motion to the mass of liquid in the bioflocculation space. Some of the circulating liquid enters the sedimentation channel S via the distributing trough T. The solids in suspension in this liquid gravitate and concentrate along the partition wall 8 and return to part A 1 of A. Water with diluted suspension enters via openings 9 the space B in which there is a sludge blanket for filtering said liquid; clarified liquid is withdrawn by troughs 18 to collecting channel 3.
