Mascara Renewable Water is a company specialised in innovative membranes water treatment solutions with the use of renewable energy.

The company developed the world's first reverse osmosis desalination technology coupled with PV solar energy, without battery nor grid regulation, to produce 10 - 5,000 m3 per day of fresh water at a competitive price to any remote location. 

The 100% solar powered desalination process fluctuates with sunshine variations, requiring no energy storage, and generating no greenhouse gas emission. Fully industrialised, the patented OSMOSUN® technology directly takes advantage of both the cost competitiveness of solar energy, the world's cheapest energy source, and reverse osmosis, the most efficient desalination technology.

Since the implementation of the first unit near Abu Dhabi with Masdar, OSMOSUN® offers a renewable alternative to supply water to off-grid locations. Units have now been installed in Polynesia, Mauritius, Mozambique, South Africa, Cape Verde, while others are being implemented in the Pacific, Northern Africa and the Caribbean.
