Global deionized water system market to hit USD 16.3 billion by 2035, expanding 2.1X amid semiconductor, biotech, and green technology growth.

NEWARK, DE, UNITED STATES, November 7, 2025 /EINPresswire.com/ -- The global deionized water system market, valued at USD 7.9 billion in 2025, is projected to reach USD 16.3 billion by 2035, marking an absolute growth of USD 8.4 billion and a compound annual growth rate (CAGR) of 7.6%. This strong growth trajectory underscores the rising need for ultrapure water across semiconductor manufacturing, pharmaceutical production, biotechnology research, and advanced laboratory operations.

From 2025 to 2035, the market is expected to grow by 106.3%, nearly doubling its size as manufacturers globally intensify their focus on sustainability, precision, and water quality compliance.

Semiconductor and Pharma Industries Lead Global Adoption

Between 2025 and 2030, the market is projected to increase from USD 7.9 billion to USD 11.3 billion, capturing nearly 40.5% of the decade’s growth. The momentum will come from rapid semiconductor fab expansions under government initiatives like the U.S. CHIPS Act, coupled with rising pharmaceutical water quality regulations and biotech advancements.

By 2035, the industry will add another USD 5.0 billion, reflecting growing adoption of zero-liquid discharge (ZLD) technologies, circular water management, and smart monitoring systems that enhance process reliability while reducing waste and energy consumption.

“Ultrapure water is now a critical enabler of modern manufacturing,” said an industry analyst at Market Data Center. “As chip production scales and pharmaceutical standards tighten, deionized water systems are evolving into intelligent, eco-efficient infrastructure.”

Mixed-Bed Systems Hold Dominance with 63% Market Share

Among system configurations, mixed-bed systems remain the leading technology, accounting for 63% of market demand in 2025. Their dominance stems from unmatched efficiency in achieving high resistivity and water purity levels essential for semiconductor wafer cleaning, pharmaceutical formulation, and precision laboratory work.

Advancements in ion exchange resins and automated regeneration are enabling manufacturers to improve system longevity while cutting operating costs. Companies like Evoqua Water Technologies and Merck Millipore have launched next-generation mixed-bed systems with integrated sensors and IoT-based quality monitoring, enabling predictive maintenance and continuous process optimization.

Medium-Capacity Systems Drive Industrial Usage

The medium-capacity segment, holding 48% of market share in 2025, continues to lead across industrial and commercial applications due to its balance between output efficiency and capital cost. Medium-capacity systems have become indispensable for automotive, electronics, and power generation sectors, providing reliable and cost-effective water treatment solutions that align with evolving sustainability mandates.
