Resumen

The shortage of drinking water in the northern coast of Peru is a major problem due to the occurrence of natural phenomena, since they contaminate the available fresh water sources and lead to the clogging of the distribution networks, exposing the surrounding people to a state of water shortage. In this work we propose the development of a seawater desalination system by electrodialysis, this technique is based on the transport of ions present in the diluted salts through selective membranes under the influence of an electric field. The simulation and mathematical modeling of the process will allow: predicting the behavior of the system, calculating the time necessary for the required desalination and obtaining the electrical energy consumption of the system. The results obtained recorded the desalination of a solution with a value of 36,500.00 ppm of diluted salts, up to 145.37 ppm. Being the solute NaCl the main one extracted, obtaining a total concentration of 54.00 ppm of Na and 83.83 ppm of Cl, values which are within the legal limits of drinking water.
