PROCESS FOR CLARIFYING AQUEOUS FLUID BY CONTACT WITH A FLUIDIZED BED OF CONSTANT FLOW HYDROXIDE SLUDGE

摘要

The present invention relates to a method for clarifying in a fluid bed settler of hydroxide sludges for the treatment of aqueous fluids, in particular water, by contact with the fluidized bed of hydroxide sludge, characterized in that introduction of the aqueous fluid is done in the decanter in a constant flow upflow, via an intake system consisting of a distributor in the form of a plurality of dispersion booms pierced with orifices. disposed relative to each other so as to emit a divergent flow together and directed towards the bottom of the settler. The present invention also relates to an aqueous fluid clarification plant comprising a fluid bed settler of hydroxide sludge.
