Electrodialysis (ED) is emerging as a cost-efficient alternative to reverse osmosis for brackish water, particularly in low-salinity regions and emerging markets. ED systems are more economical for feed salinities up to 3 g/L, making them suitable for slightly saline water sources without the high-pressure requirements of RO. Additionally, ED systems achieve higher water recovery ratios at 60% compared to 25–50% for RO to reduce water wastage. Lower operational costs stem from the absence of high-pressure pumps and reduced pre-treatment needs, while anticipated reductions in ion-exchange membrane costs could make ED a preferred technology across broader salinity ranges in the near future.
The growing affordability and reliability of solar power present significant opportunities for integrating brackish water desalination with solar microgrids. Solar-powered brackish water RO systems provide cost-effective and autonomous water solutions for off-grid and remote regions, reducing reliance on conventional energy and ensuring a secure water supply. Case studies indicate capital costs can be 10% lower, with freshwater production costs up to 50% lower than alternative energy-powered systems. High solar energy potential in arid regions, such as Chihuahua, Mexico (5.07–7.31 kWh/m²/day), further supports feasibility. Modular designs allow scalable production ranging from 10 to 2,000 cubic meters per day, enabling communities to install precisely sized systems and expand capacity as needed, while companies like OSMOSUN have successfully implemented battery-free solar desalination plants in Cape Verde and Namibia.
Membrane-based systems, led by Brackish Water Reverse Osmosis (BWRO), are projected to capture nearly 71.3% of the global brackish water desalination systems market by 2025. Their dominance reflects the lower energy requirements compared to seawater desalination, coupled with reduced operating pressures and scalable designs. While electrodialysis reversal (ED/EDR) retains 13.9% share in niche low-salinity applications and nanofiltration is widely used for selective hardness removal, BWRO remains the go-to choice for cost-efficient, high-recovery operations across municipal and industrial sectors.
