Abstract
Abstract A water distillation system which includes a storage tank for impure water and a storage tank for distilled water. Impure water is pumped through a heater to an evaporator. Impure water is also pumped through an impure water jet ejector. Distilled water is pumped through a distilled water jet ejector. The impure water jet ejector withdraws water from the bottom of the evaporator. The distilled water jet ejector withdraws water vapor from the top of the evaporator. Distilled water from the distilled water jet ejector passes through a heat exchanger in the impure water tank to heat input water. Impure water from the impure water jet ejector passes through a heat exchanger in the distilled water tank to cool the distilled water.
