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

摘要

The present invention relates to a process for the clarification in a fluidized bed of hydroxide sludge for the treatment of aqueous fluids, in particular water, by contact with the fluidized bed of sludge hydroxide, characterized in that the introduction of the aqueous fluid takes place in the decanter ascending flow at a constant flow rate, by means of an intake system consisting of a dispenser which is in the form of a plurality of ramps of dispersion are pierced with orifices arranged with respect to each other so as to emit a divergent flux and directed towards the bottom of the decanter. The present invention also relates to an installation for the clarification of the aqueous fluid, comprising a fluidized bed of hydroxide sludge.
