Taweelah reverse osmosis desalination plant sets new benchmarks for its size, efficiency and cost of water produced. Supplying 909,200m3/day, it will be 44% larger than the world's current largest reverse osmosis plant of 624,000m3/day. A major driver for the adoption of reverse osmosis instead of thermal desalination is the higher energy efficiency it offers. This plant redefines efficiency benchmarks with record low energy consumption of less than 3kWh per cubic meter. The contribution from around 50 MW of onsite solar generation will further boost the plants green credentials.Once completed, the Taweelah plant will contribute to the UAE's vision in reducing the carbon dioxide emissions, significantly reducing gas consumption by decoupling power and water production for the winter and summer seasons.
