Along with the development of the population in a region in a coastal area will be directly proportional to the need for clean water. However, the thing that usually happens is that there is an imbalance between water availability and water needs, in order to achieve this aspect in the future, further research is needed to achieve the water demand target in coastal areas. However, sea water still has a high TDS (Total Dissolved Solids) content and salinity, so it is not suitable for use. To desalinate sea water must increase the sea water temperature until conditions are above the saturation temperature. In this study, we will discuss how the influence of condenser pressure and salt concentration on aquades production and specific energy consumption to prove how capable and efficient the throttling process is in producing aquades water, which is expected to help provide water to meet water needs.
