In Saudi Arabia, a new technology for purifying drinking water using electrical charges is set to expand following a four-year agreement. This capacitive deionization technique will treat about 3,500 cubic meters of water daily, providing clean water without traditional filters or chemicals.
Stockholm Water Technology has partnered with DRC-ChemTec to implement this method and proposed using it to treat wastewater for agricultural use, removing micropollutants like pesticides and pharmaceuticals.
Currently, Saudi Arabia relies on thermal desalination and reverse osmosis, both of which have higher energy demands. Capacitive deionization offers a more energy-efficient alternative, potentially reducing waste and energy use.
Karthik Laxman, CEO of Stockholm Water Technology, highlighted the Kingdom’s leadership in sustainable water practices, driven by the need for clean water and a focus on recycling. Husam Aljarba from DRC-ChemTec noted the anticipated growth in residential and industrial water treatment sectors due to the technology’s flexibility.
The Swedish firm will supply 1,750 systems, initially focusing on drinking water before expanding into wastewater treatment. DRC-ChemTec will handle installation, service, and local manufacturing, enhancing domestic production capabilities.
Desalination currently provides 75% of Saudi Arabia’s water, producing over 13.2 million cubic meters daily.
