PROCESS FOR THE TREATMENT OF VINASEED, BY ACCELERATED EVAPORATION

Abstract

Process for the treatment of vinasse, comprising the stages: supplying raw vinasse; stabilizing the raw vinasse to a pH of 6 and 7; coagulating-flocculating the stabilized vinasse by applying a chemical coagulant at the outlet of the pump that feeds the stabilization tank and simultaneously applying a chemical flocculant at the inlet of the flow entering the stabilization tank, resulting in an aqueous phase and a solid phase (sludge); extruding the solid phase from the previous stage through a conventional press; sending the extruded solids to a drying bed for disposal; collecting the aqueous phase in an impermeable reservoir; and rapidly evaporating the aqueous phase from the previous stage by fragmenting the liquid residue through evaporators that reduce the particle size to the order of 20 to 50 µm.
