A company from the north-eastern part of Germany has designed a novel seawater desalination technology. The unique technology is based on the well-known process of mechanical vapour compression. This robust technology can be attached to any energy source, making off-grid renewable energy available for seawater desalination. Through replacing the traditional chemical seawater pre-treatment by a proprietary electro dialytic process, desalination becomes truly non-polluting. The produced water can be used for both drinking and industrial purposes. The concept of the patented ecological desalination technology has been proven. The first plant is operating on the island of Rügen, Germany. The water produced has an outstanding quality and the brine output is considerably lower than with other desalination technologies. The brine is free of added chemicals. It can be also exploited for salt recovery. The unique technology is particularly aligned to the conditions and necessities of remote areas and islands in southern EU and Mediterranean countries and around the world. The entire desalination plant will come pre-installed in two 40.-ft containers. This will make it particularly easy to install in remote and in difficult to access coastal areas and islands. The ecological valuation shows that the technology complies by far the best with the environmental requirements of sustainable development. Its higher water recovery rate produces 40% less of brine compared to reverse osmosis technology. Taking the option for salt recovery as valuable asset, the brine discharge comes to less than 10 % and increases considerably the economic outcome, the reduced specific energy consumption provided.
