Stepped Solar Stills’ Development and Improvement for Seawater Desalination

Nowadays freshwater needs were covered by fossil fuel-based desalination systems in many areas over the world. However, fuels’ excessive burning results rapid depletion and pollution of local environment as well threat to life sustainability. Therefore, through last few decades scientific community focused on relying solar energy seawater a clean alternative. Stepped stills, which convert required heat for producing desalination, are paid much attention. This article provides comprehensive analysis stepped stills’ development. Performance enhancement techniques, desalinated water production, efficiency maximum theatrical production discussed. work aims keep researchers concerned abreast improvements. Such stills low construction running costs can meet daily small communities coastal areas, islands rural especially Mideast. In conclusion, this review clarified that type still need multiple improvements enhance their quantity. Further attention should be design modified attain better efficient absorption evaporation seawater.
