Extracting fresh water from seawater requires a great deal of energy, both thermal and mechanical. Renewable energy driven desalination is becoming more viable because it employs free natural energy sources and releases no harmful effluents to the environment. Solar radiation is usually chosen over other renewable energy sources because its thermal energy can be directly applied to drive desalination systems without the inevitable energy loss associated with energy conversion according to second law of thermodynamics. Solar desalination system is classified into direct and indirect process. In this work study Direct Method is used to purify and collect fresh water. Conventional Direct desalination method has been altered and different changes are done in the system. Here Stepped type solar still is used to achieve maximum efficiency of the system. Vacuum Pump is incorporated in the system to decrease and maintain the vapor pressure of the steam in the container so that evaporating temperature is also decreased which results in increase in evaporation rate.

Solar radiation, Stepped type, Vacuum Pump, Solar Still.
