“Desalion”, a compact and movable SANSO ELECTRIC Company desalination machine was implemented for 617 days and tested at Sichang Marine Science Research Station (Aquatic Resources Research Institute, Chulalongkorn University), Sichang Island, Cholburi Province, Thailand. The utilization ratio of actual working days and effective working days was 76%. 483 tons of pure fresh water was produced for the utilization of 333 people. Fresh pure water and brine water were of WHO standards (2011) and Thailand’s drinking water quality standard (maximum allowable concentration). Brine water outlet and seawater inlet salinity experienced a 23.9% changed but suitable for coral and abalone cultured. Apart from its aquatic culturing use, the water from “Desalion” can also be used for agriculture and human consumption considering its 1000 liters per day production capability. This research also founded that “Desalion”, with more sample size, can prove to be a greatly useful tool in water production for areas or islands where fresh water access is scarce.
