Abstract

1471165 Wet separation of solids ERPAC SA 22 Oct 1974 [22 Oct 1973] 45630/74 Reading B2H [Also in Division Cl] Flotation apparatus Fig. 3 for extracting non-colloidal and colloidal materials in suspension from aqueous effluents, comprises a reservoir 1 having first and second treatment zones, a first inlet 3 in said first zone for effluent and facilitating the distribution of the effluent into the reservoir, a second inlet 12 in said first zone for flocculating and coagulating reagents disposed near the bottom of the reservoir close to said first inlet, an injection opening 12 in said first zone for water saturated with compressed air combined with or in proximity to said second inlet, and a battery 16 of rapid separation cells in said second zone for the flocculated material disposed in the reservoir opposite said second inlet and said injection opening, in the direction of circulation of the effluent to be treated. The non- colloidal material e.g. fibres, is recovered from the surface between the partitions 19 in the first zone, and the flocculated colloidal material is recovered from the surface above the battery 16 of lamellar cells.
