EDI Water System – Continuous Production of Ultra-Pure Water

An EDI water system (Electrodeionization system) is an advanced water purification system that produces ultra-pure water continuously without using chemical regenerants. It combines ion exchange and electrical current to remove ionic contaminants, making it ideal for pharmaceutical, laboratory, and industrial applications.

How an EDI Water System Works

• Water is first treated by reverse osmosis (RO) to remove most dissolved salts.

• The EDI module then uses ion exchange resins and electricity to remove remaining ions.

• The system continuously regenerates itself, producing consistent ultra-pure water.

Benefits

• Continuous supply of ultra-pure water

• No chemical regeneration required

• Low maintenance and operational cost

• High water recovery and efficiency

• Protects sensitive equipment and processes

Applications

• Pharmaceutical manufacturing (WFI and purified water systems)

• Laboratory and analytical applications

• Electronics and semiconductor industries

• High-purity industrial processes
