Abstract:

Solar energy is an unconventional source of energy which may be utilisedfor water purification. Portable water accessibility by the whole mankind is still difficult. In this paper a new kind of still, painted in white from inside is analysed. Nano particles(Al2O3) were also added to the basin water to increases heat transfer and the productivity. The distillation performance experimentation has been conducted at the Jabalpur Engineering College, Jabalpur India (23° 10' N, 79° 59' E). The performance of proposed still has been compared with conventional still of same dimensions. The conventional still with blackened inside surfaces yields 2605 ml/m2 and the proposed still produces 3258 ml/m2 in a day. Hourly efficiency of both still has been also compared in this paper.

Keywords:
