Development of solar still for water purification and its performance analysis

Desalination process through solar still has been found to be the most economical technique, as it makes use of a free source of energy. The main drawback of this equipment is its low productivity. Thus, numerous enhancements have been developed throughout the years to improve its performance. In th...

description Desalination process through solar still has been found to be the most economical technique, as it makes use of a free source of energy. The main drawback of this equipment is its low productivity. Thus, numerous enhancements have been developed throughout the years to improve its performance.
