The recirculation of industrial wastewater in the cost of reuse of the process. Rev. Inv. Cs. Agro. y Vet. [online]. 2021, vol.5, n.15, pp.172-187.

The objective of the research was to evaluate the recirculation of industrial wastewater and its influence on the reuse cost of the process. Material and methods The research was of the experimental type, descriptive-explanatory level, applied research. Results the DS N°003-2002-PRODUCE norm, establishes the Maximum Permissible Limits and Reference Values for the tannery industrial activity with a pH between 6-9, temperature 35°C, the MATLAB tool was used, which collects tests of the tannery process, as indicated by the UTM coordinates. The total costs (S/d): 1945.36 to 1870.98, depending on the wastewater recycling (X1) from 0.6 to 0.75, the withdrawal load of the treatment plant (X2): 33.22 Kg/h to 39.41 Kr/h and the withdrawal load in the discharge to the source (X3): 19.72 Kg/h to 10.57 Kg/h. Discussion it was evidenced that the treatments X1, X2, X1 X2, influenced the reuse costs of the process. Conclusion the analysis of the reuse cost of the process depends on the percentage of recycling of the wastewater from the treatment plant, the percentage of withdrawal in the treatment plant and both treatments as the recycling and the percentage of withdrawal in the treatment plant.
