Use of purified ocean water has been advancing in Saudi Arabia. We offered support by repeatedly reviewing materials and maintenance methods of the infrastructure facilities to cater to significant regional differences in ocean water properties. Japan offers use of Reverse Osmosis Membranes which reduces the cost of desalination. We also provide customized Reverse Osmosis Membranes suitable for regional seawater conditions, in order to maintain its performance.

Ever since the 1960s, desalination of seawater has been promoted to address the issue of groundwater depletion. The reverse osmosis method, with remarkable energy efficiency and lower desalination cost, has been widely used for this purpose.

-An emergency team of Japanese experts was dispatched when the reverse osmosis membrane showed signs of rapid deterioration. Finding out that heavy metals contained in the Red Sea water were causing the problem, they reviewed the materials and maintenance methods and developed the most suitable type of membrane for stable efficiency.
