Fresh Water Generator Fresh Water Generator is used to desalinate seawater for the ships. There are two types fresh water generator, R/O type and Low-pressure vapor type. Low-pressure vapor type is most widely used in commercial ships because it utilizes wasted engine jacket water or steam while sailing. The engine jacket water and steam can be utilized as a heat-source, and Shell & Tube type and Plate type are available. The seawater is heated by various heat-sources under the vacuum state, and then vaporized accordingly. The vaporized seawater is desalinated in separate filtering unit before condensed, and then fresh water is produced. Meanwhile, a salinity of produced fresh water shall remain at 0~10 ppm . Fresh Water Generator is comprised of vaporizer, condenser, demister, salinometer, distillate pump, ejector and steam injector. Multi-stage Fresh Water Generator can achieve high efficiency when large amount of fresh water is required with small amount of calories due to...
