Technology Overview: Principles of Electrochemical Membrane Desalination
Electrochemical membrane desalination systems represent a rapidly advancing segment of water treatment technology, leveraging electrical potential and selective ion transport to remove salts and impurities from water. Unlike traditional pressure-driven reverse osmosis (RO), these systems utilize ion-exchange membranes and electrochemical gradients, offering potential advantages in energy efficiency, fouling resistance, and selective ion removal. The two principal technologies in this category are electrodialysis (ED) and capacitive deionization (CDI), both of which are seeing renewed interest and commercial development as of 2025.
In electrodialysis, alternating cation and anion exchange membranes are arranged between electrodes. When a voltage is applied, ions migrate through the respective membranes, concentrating salts in one stream and producing desalinated water in another. This process is particularly effective for brackish water and industrial wastewater, where total dissolved solids (TDS) are moderate. Recent advances focus on improved membrane materials, such as monovalent-selective membranes, and on system integration for hybrid desalination plants. Companies like Evoqua Water Technologies and SUEZ (now part of Veolia) are actively developing and deploying ED systems for municipal and industrial clients, with ongoing projects in North America, Europe, and Asia.
Capacitive deionization, meanwhile, employs porous electrodes to adsorb ions from water under an applied electric field. When the electrodes are regenerated, the ions are released and flushed away. CDI is particularly attractive for low-salinity feedwaters and applications requiring selective ion removal, such as lithium extraction or water softening. Recent years have seen the emergence of advanced electrode materials—such as carbon aerogels and metal-organic frameworks—improving both capacity and selectivity. Companies like DuPont and Aker Carbon Capture (which has diversified into water treatment) are investing in CDI research and pilot-scale deployments.
Looking ahead to 2025 and beyond, the outlook for electrochemical membrane desalination is shaped by several trends. First, the integration of renewable energy sources with ED and CDI systems is being piloted to further reduce operational costs and carbon footprint. Second, digitalization and real-time process monitoring are enabling smarter, more adaptive operation, as seen in pilot projects by Veolia and Xylem. Finally, the push for circular water use in industry is driving demand for modular, scalable electrochemical systems that can be tailored to specific contaminants and recovery goals.
As of 2025, electrochemical membrane desalination is transitioning from niche to mainstream, with commercial deployments expanding in regions facing water scarcity and industrial water reuse mandates.

Cost Efficiency and Performance Metrics: Comparing to Conventional Desalination
Electrochemical membrane desalination systems, such as electrodialysis (ED) and capacitive deionization (CDI), are gaining traction as alternatives to conventional thermal and reverse osmosis (RO) desalination, particularly for brackish water and low-to-moderate salinity sources. In 2025, the cost efficiency and performance metrics of these systems are under close scrutiny as the water sector seeks more sustainable and energy-efficient solutions.
A key advantage of electrochemical membrane technologies is their lower specific energy consumption when treating feedwaters with salinity below 10,000 mg/L. For example, modern ED systems can achieve energy requirements as low as 0.4–1.5 kWh/m³ for brackish water, compared to 1.5–3.0 kWh/m³ for RO under similar conditions. This efficiency is largely due to the selective ion transport mechanism, which avoids the need to pressurize the entire feed stream, as is necessary in RO. Companies such as Evoqua Water Technologies and SUEZ Water Technologies & Solutions are actively deploying and optimizing ED systems for municipal and industrial clients, reporting operational cost reductions of up to 30% in suitable applications.
Capacitive deionization (CDI) is another electrochemical approach that has seen rapid development. CDI systems, offered by companies like DuPont (following its acquisition of several water technology firms), are particularly effective for low-salinity water, with energy consumption as low as 0.2–0.8 kWh/m³. However, CDI’s cost efficiency diminishes at higher salinities, making it less competitive for seawater desalination compared to RO. Nevertheless, the modularity and low-pressure operation of CDI units make them attractive for decentralized and small-scale applications, where capital and maintenance costs are critical factors.
In terms of capital expenditure (CAPEX), electrochemical membrane systems generally require less robust infrastructure than thermal desalination plants, and their modular design allows for incremental scaling. However, membrane replacement and fouling remain ongoing challenges, impacting long-term operational expenditure (OPEX). Leading manufacturers such as IONPURE (a subsidiary of Evoqua) are investing in advanced ion-exchange membranes with improved durability and anti-fouling properties, aiming to extend membrane lifespans and reduce maintenance intervals.
Looking ahead to the next few years, the outlook for electrochemical membrane desalination is positive, especially as water utilities and industries seek to decarbonize operations and reduce lifecycle costs. Ongoing R&D, supported by industry leaders and public-private partnerships, is expected to further improve energy efficiency, membrane performance, and system integration. As a result, electrochemical membrane desalination is poised to capture a growing share of the market for brackish water and industrial reuse, complementing rather than replacing conventional RO and thermal technologies.

Challenges and Barriers: Scalability, Fouling, and Economic Viability
Electrochemical membrane desalination systems, such as electrodialysis (ED) and capacitive deionization (CDI), are gaining attention as alternatives to conventional reverse osmosis (RO) for water treatment. However, as these technologies move from pilot to commercial scale in 2025 and beyond, several challenges and barriers remain, particularly regarding scalability, fouling, and economic viability.
Scalability is a primary concern. While electrochemical systems have demonstrated efficiency in small- and medium-scale applications, scaling up to municipal or industrial capacities introduces complexities. The modular nature of ED and CDI stacks allows for some flexibility, but the integration of large numbers of cells increases system complexity, energy management challenges, and maintenance requirements. Companies such as Evoqua Water Technologies and SUEZ are actively developing larger-scale ED systems, but widespread deployment at the scale of conventional RO plants is still limited. The need for robust, cost-effective stack designs and power management systems remains a barrier to broader adoption.
Fouling—the accumulation of organic, inorganic, or biological materials on membrane surfaces—remains a significant operational challenge. Fouling leads to increased energy consumption, reduced ion selectivity, and more frequent cleaning cycles, which can shorten membrane lifespan. In ED, scaling and organic fouling are particularly problematic in high-salinity or poorly pretreated feedwaters. Companies like DuPont, a major supplier of ion exchange membranes, are investing in advanced membrane chemistries and surface modifications to mitigate fouling. However, the effectiveness of these solutions in diverse real-world water matrices is still being evaluated, and the need for reliable, low-maintenance anti-fouling strategies persists.
Economic viability is closely tied to both capital and operational expenditures. Electrochemical systems can offer lower energy consumption than RO for brackish water desalination, but membrane costs, stack replacement, and system complexity can offset these savings. The price of high-performance ion exchange membranes, a key component, remains relatively high, and their durability under continuous operation is a concern. Companies such as 3M and IONPURE (a subsidiary of Evoqua) are working to improve membrane longevity and reduce costs, but as of 2025, the economics of large-scale electrochemical desalination are still less favorable than mature RO systems for seawater applications.
Looking ahead, overcoming these barriers will require continued innovation in membrane materials, system engineering, and process integration. Collaboration between technology developers, membrane manufacturers, and end-users will be essential to address the technical and economic challenges that currently limit the widespread adoption of electrochemical membrane desalination systems.
