Desalination is the answer to long-term water security, but it’s also expensive and energy-intensive. The good news is that scientists are developing viable solutions. For many years, the most common method of desalination has been reverse osmosis (RO). But RO desalination systems require connection to the electricity grid. Not only is this expensive, it is often inaccessible to isolated regions. This is why sustainable off-grid desalination systems powered by renewable energy are essential. With revolutionary technology developed by MIDES, these use a sustainable, low-energy process to produce safe drinking water from seawater. Electro-active bacteria desalinate and sterilize water, making it suitable and safe. “This technology offers new options to provide clean water and wastewater treatment to small, isolated locations without electricity,” said Frank Rogalla, director of innovation and technology at Aqualia and a member of the project team.
