Electrodialysis Desalination System Market Report 2026

The electrodialysis desalination system market size has grown strongly in recent years. It will grow from $0.61 billion in 2025 to $0.67 billion in 2026 at a compound annual growth rate (CAGR) of 9.7%. The growth in the historic period can be attributed to increasing freshwater scarcity, expansion of brackish water treatment projects, adoption of membrane-based desalination technologies, growth of decentralized water treatment systems, rising industrial water reuse practices.

The electrodialysis desalination system market size is expected to see strong growth in the next few years. It will grow to $0.96 billion in 2030 at a compound annual growth rate (CAGR) of 9.5%. The growth in the forecast period can be attributed to increasing investments in sustainable desalination, growing demand for low-energy water treatment technologies, expansion of industrial water recycling, rising focus on renewable-powered desalination, increasing adoption in water-stressed regions. Major trends in the forecast period include increasing adoption of energy-efficient electrodialysis systems, rising deployment of continuous desalination plants, growing integration of solar-powered electrodialysis units, expansion of modular desalination solutions, enhanced focus on low-salinity water treatment.

The increasing scarcity of freshwater is expected to drive the growth of the electrodialysis desalination system market going forward. Freshwater scarcity refers to a situation where the available clean and usable water supply is insufficient to meet the demands of populations, ecosystems, or industries. This scarcity is intensifying due to rapid population growth, which places additional pressure on limited water resources. Electrodialysis desalination systems help mitigate freshwater scarcity by converting saline and brackish water into clean, usable water through energy-efficient ion separation technology. For instance, in January 2025, according to GreenMatch, a UK-based solar energy company, over 4.4 billion people, representing 27% of the global population, lacked access to clean drinking water in 2024, and by 2025, around 1.8 billion people were projected to face complete water scarcity. Therefore, the increasing scarcity of freshwater is fueling the growth of the electrodialysis desalination system market.

Key companies operating in the electrodialysis desalination system market are focusing on developing innovative technologies such as solar-powered desalination to provide sustainable, low-cost drinking water without dependence on batteries or grid power. Solar-powered desalination refers to the use of solar energy to directly power the desalination process, adjusting water production dynamically based on sunlight availability. For instance, in October 2024, the Massachusetts Institute of Technology (MIT), a US-based research and educational institution, developed a battery-free solar-powered method to purify salty groundwater. This advanced system employs flow-commanded current control to adjust water flow and electrical current in real time, efficiently desalinating brackish groundwater without batteries. It can produce up to 5,000 liters of drinking water per day, offering a scalable and energy-efficient solution for communities with limited freshwater access.

In May 2023, Xylem Inc., a US-based company that provides water technology, acquired Evoqua Water Technologies Corp. for $7.5 billion. This acquisition enables Xylem to build the world’s most advanced platform to address key water challenges, including scarcity, quality, and resilience, while expanding its expertise in the electrodialysis desalination system market. Evoqua Water Technologies Corp. is a US-based company that manufactures electrochemical desalination systems using low-pressure electrodialysis membrane technology.
