Desolenator is a patented technology that uses 100% solar power to distil complex water types (including seawater, heavy metal contaminants and brackish) into clean water. Our installation can produce over 250,000 litres of water a day and is modular. Our technology is easy to install, has no internal filters and membranes that need to be replaced, and has an automatic cleaning process to minimise maintenance. Unlike other purification technologies Desolenator is not rendered obsolete by changing input water types but instead future-proofs supply at a low levellised cost of water ($1/m3) through eliminating the costs of fuel and consumables.
