Summary on Assay for Leather Processing Effluents
A new alternative for the treatment of effluent waters from the Leather Processing Industry was tested at several facilities in Colombia. The parameters for identification of pre-treatments operations where done to adjust the conditions of effluents for optimal pH, filtration and flocculation. The products used in this study were NS 20 (now ACCELOBAC® 20), ACCELOBAC® 5000, Maintain® D and a mixture of them. The two products selected for larger removal of the total COD after a 24 hour period were NS 20 and Maintain® D. Once those products were selected the concentration ratios for each of them were 80; 20 per application. The variables measured during the study were temperature, product quantity and aeration. The optimal temperature for the product total microorganisms growth acceleration was 45°C.
