PERFORMANT INSTALLATION FOR PURIFICATION AND DESALINATION OF SEA-WATER FOR CRUISE SHIP
Abstract
The current paper presents a more efficient system that has been required to obtain higher quality feed water for cruise ship. The fresh water reserves must be completed with desalination water that comes from the ship’s own desalination installation, wich must be carried on board of cruise ships. If salt and other substances in the sea water were eliminated, sufficient pure water for human consumption but also for other purposes would be produced. The salt water has generally been removed prior to injection into the boiler. After desalination, the particles such as iron and copper become greater problems. This particles determine corrosion of installation and must returning from the condensate system and depositing in the boiler. If iron is in a soluble form and not a particulate form, it can produce precipitates such as iron phosphates and iron silicates which are extremely adherent deposits. The resultant precipitate has a strong affinity for tube metal through surface attraction. Water flow and circulation of particles in installation, will provide a force to keep the particles in suspension and moving. To maintain the desalination installation in function for a long time, it is important to have the optimum concentration of the suspended particles which are continuously moving through the installation.
