The following research work consists of the implementation of a wastewater treatment system for zinc sheet phosphating, for the reduction of nickel and zinc metals in the prepatinated plant, in the company Electrochemical Industries S.A. As part of the continuous improvement in the organization, the treatment system will be implemented within the facilities of the organization in order to reduce the nickel and zinc metals that currently exceed the maximum admissible values established by Peruvian Law N ° 29338, Water Resources Law. For our treatment we will use supplies such as: sodium hydroxide, as coagulant; calcium oxide, as a flocculant; nitric acid, for the neutralization of pH; and to avoid the proliferation of bacteria we will use doses of sodium hypochlorite (bleach). Currently, the industrial company uses these inputs in its crude lead refining process, which will facilitate the acquisition of these controlled reagents. The tests to define the treatment process, to reduce the concentration of metals, was carried out in the laboratory of the company Industrias Electroquímicas S.A. using the jars test tool, which has allowed us to obtain the appropriate dosage for the use of the aforementioned inputs. First, we will determine what causes the high concentrations of nickel and zinc in the effluent using the Ishikawa diagram. After putting the selected method of precipitation into practice, the heavy metals will be monitored in the effluent, obtaining nickel and zinc concentrations within the maximum admissible values according to the D.S. 0021-2009-Vivienda (See annex 32). Finally, we observe that due to the implementation of this proposed system in the organization; the economic impact evaluated is positive, since the period of recovery of the investment is 8.3 months and the company would be receiving savings of S/.160 739.4 from the Second year. These results were evaluated with respect to the costs, which are currently originating in the organization, of outsourcing its effluents to a service provider company.
