Description:	In Colombia, the largest percentage of tanneries are concentrated in the municipality of Cundinamarca, mainly in Villapinzón, a major study sites. Its discharges are sent  to the upper basin of the Bogotá River. The tanneries are among the industrial sectors that have the greatest negative impact on water resources, specifically in the unhairing process because the mass ratio 1: 1 is operated on the weight of the furs to work. In order to evaluate options to minimize the negative impacts generated on the Bogota river by high volumes of effluents (average capacity of 300 drums of fur bump, average weight of a fur 25 kg), this study evaluates the feasibility of reuse discharges generated in the unhairing process through physical chemical treatment, assuring not to affect the quality of the end product. The water recirculation on the unhairing process does not increase operational costs. Instead, it represents a savings and reduces the negative environmental impact generated, considering reuse a water volume of about 50%.
