ABSTRACT
Industries dedicated to the treatment of skins are big consumers of water and, as a consequence, big producers of liquid effluents. These effluents are characterized by their high chemical oxygen demand (COD), as well as colors and a high content of salts, oils and fats, and solids, due to the reagents used during the production process. As a result, these effluents have a high pollutant potential and need to be treated before their discharge or elimination.
