About Us

Increases in population and life quality are increasing the stress on existing water resources, many have already been depleted or polluted – the world is simply running out of available water. The solutions are clear: increased water usage efficiency, wastewater reuse and desalination.

The standard solution for industrial water purification, reuse and desalination is Reverse Osmosis, but Reverse Osmosis is a mature technology that is sensitive, limited in its effici­­ency and has reached its limits.

Desalitech’s Reverse Osmosis systems are rapidly replacing traditional water purification methods, including reverse osmosis. Fortune 500 companies around the world rely on these robust and adaptive systems to streamline their operations while saving significant costs through maximum water recovery rates, lower energy consumption and lower maintenance requirements.

Desalitech’s technology was introduced to the desalination market in 2009 as an energy-saving breakthrough for making drinking water from seawater. With the increased use of reverse osmosis for industrial, brackish and wastewater treatment, Desalitech optimized and simplified the technology to achieve an even greater breakthrough for reliable, high-recovery purification of a broad range of water sources.

In 2013, Desalitech established its headquarters and manufacturing operations in the USA. Since then, the company has more than doubled its sales each year and has become the trusteed solution provider and partner of many industry leaders. Desalitech has earned numerous global awards for innovation and business success, including the 2016 Breakthrough Water Technology Company of the Year.

Desalitech’s mission is to lead the world to its inevitable water future – one of great water reliability and efficiency.
