Analyses on utilisation of solar energy as a sustainable source of clean water production

Abstract

Availability of clean water depends on either availability of naturally clean water or supply of sustainable source of energy that can be utilized for clean water production process. Solar energy can be utilized as a sustainable energy means for clean water production process. Prospects of solar energy utilization for water pumping and desalination exist in Pakistan on account of availability of solar energy for most of the day hours and round-the-year. Therefore, research survey is carried out of thermal and solar powered clean water production processes in Pakistan. In this paper, a comparative analysis of conventional thermal powered and solar powered clean treatment processes is carried on parameters of production costs, environmental sustainability and selfcontained nature of solar powered clean water production process.
