Experimental Investigation on Various Extracted Liquids into Useful Products using Solar Distillation

Abstract

In order to use solar energy to convert raw ground and surface water into clean potable water, several distillation systems have
been investigated so far. However, to be sustainable, the productivity of these systems must be as high as possible. Tubular solar stills
(TSS) were investigated as one of the more productive solar distillation systems. The current study aims to improve the productivity of
tubular solar stills by exploring different cover materials. The experimental study was carried out on four different TSS setups with cover materials made of polyvinyl chloride (PVC), polycarbonate, acrylic, and glass. In comparison to other materials, it has been observed that the TSS with glass cover gives the maximum productivity (6.23 L/m2) and daily exergy and energy efficiency (7.67%, 71.56%, respectively) for the same water depth of 0.5 cm in each basin. In this study the attempt has been made to design, fabricate and performance analysis of the passive solar still for the cow urine distillation. It is well known fact that the cow urine has huge number of medicinal values, for the purpose of distillation of cow urine the use of solar still and effect of different performance parameter is illustrated.A single slope passive solar still is designed with absorber plate dimension of 0.8 m2with 18.520 of tilt angle. The analysis of effect of different performance parameter such as water depth, wind velocity and solar radiation on the yield is experimented.
