Conceptual context of tilted wick type solar stills: A productivity study on augmentation of parameters

Abstract Life, on earth, is active only because of water devouring. Nature has provided a number of water resources such as surface water for instance rivers, lakes, springs, ground water and so on. By artificial means, man has created water storage systems such as excavated dams, check dams, reservoirs, tanks etc., to meet the basic water requirements throughout the year. But ever-growing population and poor water management skills of individuals have driven the globe towards serious water crisis. Solar distillation fills the gap between water scarcity and water productivity and remains one of the simplest methods of producing pure drinking water. Though many models in solar stills are being used across the globe, tilted wick type still excels with outstanding performance in the production of pure water. In this review, an attempt has been made in particular to study the factors that are involved in increasing the performance of tilted wick type solar distillation stills. This review covered the initiatives taken from the year 1985 being the first initiative in tilted wick type model to final tilted wick model on 2020 based on published articles.
