Crystallization procedure
WebThe freezing process, also called crystallization, involves cooling salt water to form crystals of pure ice. The ice crystals are separated from the unfrozen brine, rinsed to remove residual salt, and then melted to produce fresh water. Freezing is theoretically more efficient than distillation, and scaling as well as corrosion… Read More WebCrystallization Process Development.
