Electrodeionization (EDI) systems are advanced water treatment technologies that produce ultra-pure water without the need for chemicals by combining ion exchange resins, ion exchange membranes, and direct current. Typically used after reverse osmosis, EDI systems further reduce water conductivity to achieve ultra-purity. They are widely used in industries requiring high-purity water such as power plants, pharmaceutical production, laboratories, and process industries. By eliminating chemical usage, EDI systems reduce operational and maintenance costs. The system includes modules, control panels, frames, piping, and control valves, and can be customized based on capacity requirements.
