Storing large quantities of fresh water on board ship is costly and takes up valuable space. GEA offers an alternative solution, in the form of a process and technology for sea water desalination, which can be used to generate up to 30 tons of fresh water a day.
The principle of sea water desalination by evaporation
Desalination is based on the principle of evaporation: sea water that has been filtered through a coarse mesh is evaporated in a heat exchanger plate stack that is made of titanium to precipitate out salt and impurities. A further plate stack then condenses the steam into drinking water. A salt measuring cell checks for residual salt content, which should be below four parts per million (ppm). If a value below four ppm can be reliably maintained, then the desalinated water can be passed to a storage tank before further treatment by UV sterilization.
An output of 5-30 tons a day
A re-hardening filter finally returns enough hardness to the fully demineralized water to make it suitable for human use. Whether for the shower room, for the galley or for scrubbing – our systems enable output of between five tons and 30 tons a day, which should easily cover the everyday requirements of container ships, LNG tankers, bulk carriers or freighters.
