Electrodeionization

Electrodeionization (EDI) is a water purification process that uses electric currents and special membranes to remove ion impurities, such as salts and minerals, from water. It combines traditional ion exchange techniques with modern filtration, allowing continuous and chemical-free removal of contaminants. In EDI, electrodes create an electric field that drives ions away from the water, trapping them in resin chambers and producing pure water. This method is efficient, environmentally friendly, and widely used in industries like power generation, pharmaceuticals, and electronics, where high-purity water is essential.
