Experimental Study of Innovative Design for Solar Still Desalination

Abstract

Solar still is a cost-effective and sustainable desalination process since it uses abundant solar energy to  lower energy-related expenditures. For the first time, this study provides a new concept of free water production employing Solar Still with a built-in parabolic trough collector (PTC). The suggested solution is based on integrating a conventional solar still (CSS) and a PTC supported by an absorbent plate that serves as a thermal storage medium for the systems. The effect of integrating PTC on conventional single slope solar still as well as performance is being explored experimentally. The results show that the maximum cumulative productivity per hour for the seven-hour work period is 921 ml, and the highest overall productivity is 2451 ml and the maximum efficiency per hour of the modified Solar Still 44.9 %.
