  • WASTEWATER TREATMENT COMPRISING ELECTRODISSOLUTION, FLOCCULATION AND OXIDATION
    Publication number: 20130153509
    Abstract: The present invention claims a process to reduce COD, TOC, and total solids from a contaminated liquid medium, which comprises of the following stages: feed an electrolytic cell provided with electrodes with the contaminated liquid medium; apply a constant direct current through said electrodes; flocculate the solids present in said contaminated liquid medium by adding coadjuvant agents, remove sludge and supernatant obtained; and oxidize the supernatant through oxidizing agents.

  • Process to reduce the chemical oxygen demand, total organic carbon, and total solids in vinasse by electro-flotation/oxidation
    Patent number: 8425755
    Abstract: 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.
