An experimental investigation for desalinating seawater into fresh water with permanent magnets and electromagnets

Year: 2025

Type: article

Abstract: The study explores a novel approach to desalination by using magnetic water treatment as a solution to the global water crisis caused by contaminants, rising temperatures, and human activity. The research aims to create artificial sea water by varying water concentrations to reduce salinity content, rather than brine rejection. The treatment uses permanent magnets and electromagnets to weaken or break the bonds of NaCl and reduce their concentration. This experiment is two-part: first, it created a permanent magnetic field , followed by an electromagnetic field with different direct current (DC) voltages. The dilution ratio and treatment controlled the variation of all parameters. This experimental approach yielded positive results when authors used magnetic water treatment for desalination . Permanent magnetic treatment (PMT) got rid of 20 % of the chlorides in the water that was treated, while electromagnetic treatment (EMT) got rid of 15.37 % (4V) – 54.61 % (10V). Sodium achieved removal rates of 13.6 % for PMT and 6.52 % (2V) – 13.35 % (6V) for EMT. Magnetic desalination research and development could address the global water crisis, with continuous testing and development establishing its suitability for various countries and applications.
