A Review of Conventional and Horizontally Double Sloped Solar Still

A desalination system works on electricity or a convention fossil fuel. Where thermal energy is extracted which leaves carbon residue and other greenhouse gases behind, which a major reason behind ozone depletion and global warming and may other health hazards for mankind. Desalination using a non-conventional resource will help. The desalination using solar energy is one-time investment for lifetime production of pure water up to 15 to 25 years. In this dissertation, multiple method of desalination has been discussed. The productivity of passive solar stills can be improved or enhanced by using various storage materials or by some simple modification in the design of still. These solar still can be used to convert brackish water into fresh water. Conventional solar still has low productivity and productivity of solar still many research iterates and puts their effort consistently. Many researchers have used metal particles of Nano sized to improve the thermal efficiency of the still. In this project, conventional solar still is compared with Horizontally Double Sloped solar still which resulted in increase in efficiency and productivity in the process of desalination which can be carried out by only using the energy from the sun.
