Description Water is the most important element for sustaining life on earth. 71% of the earth’s surface is
water-covered, and the oceans hold 96.5 percent of all earth’s water which is salty and cannot be
used directly. Water also exists in rivers, lakes, in icecaps and glaciers which is the fresh water
resource on earth and can be made into use directly. The ratio of salty water to fresh water on
earth is around 40 to 1. However population growth and industrialization has resulted in the great
demand of fresh water for different domestic, agricultural and industrial usage. Also, the earth’s
fresh water is very unevenly distributed. Fresh water shortage problem has become a major
problem these days and so desalination of the sea water is the only option left.
In the present research article an experimental study was conducted to analyze the performance
of stepped solar still with and without using phase change materials. Their performance was
compared on the basis of the energy and exergy efficiencies. In this study magnesium nitrate
hexa-hydrate and paraffin wax were used as phase change material. The economic cost analysis,
uncertainities and water quality was also tested. The experiment was conducted in the premises
of SHUATS Allahabad U.P. INDIA. It was observed from the experiment that the total
productivity of the still using PCM was higher than the still without PCM. The experiment was
conducted in the hot summer days in the month of April-May. The cost study shows that the
price of the output per litre reduces or decreases when the life expectancy is presumed to be 30
years. A comparative cost examination is also carried out for all three still i.e. still without
applying PCM, still applying Mg(NO3)2.6H2O as PCM and still applying Paraffin Wax as PCM.
The still applying PCM were found to be more economical for the small-scale usage as the
productivity is obtained in off-sunbeam hours also. The experimental uncertainity was obtained
as 17.69%. The quality of distillate obtained was observed as the pH value and the TDS of the
output was 7.2 and 45 ppm.
