The most commonly used process for seawater desalination is reverse osmosis. The seawater is desalinated under high pressure via a reverse osmosis membrane. The product water is salt-free water of drinking water quality. Common reverse osmosis plants produce water volumes between 20 and 2000 tons per day. The plant technology can be adapted to individual needs, available space and required water volumes. The plant technology is fully automated and can be operated via simple push buttons. The operating data of the plant technology are displayed in a touch panel. Operating parameters can also be adjusted there.
