Comparative Study of Basin Type Double Slope Active Solar Stills Based on Energy Metrics

Water is one of the crucial components for the existence of life on our planet. This gift of nature has several usages and applications. One can see a clear implication of water availability on industries, civilization, livelihood, etc. Though a plethora of water is available, however, not all of it is of direct use; only 2.6% of total available water is freshwater and of that only 1% is in human reach. Unfortunately, that little amount is also prone to several impurities, mainly because of human activities. Indian ministry of water resources, United Nations, UNICEF and several other organizations reported on the ignorance of environmental norms pertaining to water discharge by many industries and organizations. All such ignorance somehow enhances water scarcity. The investigation of active solar desalination system working in dynamic mode is one of the best considerations to lessen the water scarcity problem. This work focuses on energy metrics scrutiny of basin type double slope active solar desalination systems, and these solar desalination systems have been judged against each other on the grounds of energy metrics.
