Resumen
Due to the ever increasing requirements and supervision of environmental agencies on the disposal of industrial effluents in receiving bodies, the industries are looking for properly treating their wastewater and, therefore, require a treatment system that is efficient. This study analyzed the efficiency of the wastewater treatment system generated by the leather industry activity. The wastewater treatment system studied consisting of primary, secondary treatments (decantation and aeration ponds with thorough mixing) and tertiary (polishing pond). To determine the efficiency of the treatment system, the parameters pH, COD, BOD, Total Chromium, Sulfides, Ammonia, Oils and Greases and Solids Settleable were analyzed. The results showed good efficiency in the removal of the analyzed parameters, especially for the Chrome Total, Ammonia and Solid Settleable parameters.
