Various techniques to enhance distillate output of tubular solar still: A review

Abstract

The necessity of freshwater is rising due to the expanding residents as well as fast urbanization. Besides, concerning the drinking purpose, clean water represents a very crucial role in several applications like batteries, pharmaceuticals, automobiles and different research and development laboratories. There are many freshwater generation techniques available, but solar distillation is one of the most natural and cheapest methods. Present review paper exhibits the researchers work on the tubular solar still to enhance the distillate output. It covers the working principle and several metrological parameters like the temperature of the water, solar intensity, glass cover temperature etc. Various techniques to improve the distillate output of tubular solar still also included in the present review paper. At last, several future researches works on tubular solar still also included in this review paper. - 2019 Elsevier B.V.
