Marais’ (2018) still variation 3 was used to design a solar still to improve still productivity performance: • By using an external condenser that will reduce the available condensation area and drive condensation away from the cover surface. • By using active fluid flow to circulate humid air and, or water through the solar still. • By reducing energy losses of the cover surface and energy accumulation of the back wall.en© 2023 University of Pretoria.
