Electrodeionization EDI Polishing Module Ultrapure Water Market (2026): Market Leaders Powering Global Water Purification

MARKET INSIGHTS

Global Electrodeionization (EDI) Polishing Module Ultrapure Water Market size was valued at USD 1.47 billion in 2025. The market is projected to grow from USD 1.58 billion in 2026 to USD 2.94 billion by 2034, exhibiting a CAGR of 7.2% during the forecast period (2025–2034). The growth is being driven by escalating demand for ultrapure water in semiconductor and microelectronics manufacturing, stringent pharmaceutical regulatory requirements, and the global expansion of semiconductor fabrication capacity.

Electrodeionization (EDI) polishing modules are advanced water purification systems that combine ion exchange resins with ion‑selective membranes and a direct electrical current to continuously remove ionized and ionizable species from water, producing ultrapure water with resistivity levels typically reaching 18.2 MΩ·cm. Unlike conventional deionization processes, EDI operates without the need for chemical regenerants, making it a more sustainable and cost‑efficient solution. These modules serve as a final polishing stage in ultrapure water treatment trains, downstream of reverse osmosis systems, and are widely deployed across semiconductor fabrication, pharmaceutical manufacturing, power generation, and laboratory applications.

Global expansion of semiconductor fabrication capacity— including significant investments in chip manufacturing facilities across the United States, South Korea, Taiwan, and Europe— is a particularly strong demand catalyst. Key players operating in this market include Veolia Water Technologies, Xylem (Evoqua Ionpure), DuPont Water Solutions, SnowPure LLC, Organo Corporation, Newterra, Applied Membranes Inc., Aquatech International, Deionx, and Pure Water Group.
