Process to reduce the chemical oxygen demand, total organic carbon, and total solids in vinasse by electro-flotation/oxidation

摘要

The invention relates to a novel process for reducing the chemical oxygen demand (COD), total organic carbon (TOC) and total solids of non-contaminating residues from ethanol distilleries, by means of electro-flotation/oxidation techniques using an electrolytic cell outfitted with galvanized steel electrodes as a function of the initial pH of the medium, the current density and the concentration of H2O2.
