Largest conversion capacity from thermal desalination to reverse osmosis technology

The Largest conversion capacity from thermal desalination to reverse osmosis technology is 600,000 m³/day and was achieved by Shuaibah Three Water Desalination Company (KSA), in Shuaibah, Saudi Arabia as verified on 21 August 2025.

Converting desalination capacity from thermal to reverse osmosis has a positive impact on the environment and sustainability. RO uses significantly less energy, which reduces greenhouse gas emissions and dependence on fossil fuels, making it easier to align with national net-zero targets. It also requires less seawater intake for the same freshwater output, lowering stress on marine ecosystems and reducing brine discharge volumes. Together, these factors make RO a cleaner, more efficient, and more sustainable alternative for long-term water security.
