Drinking seawater: Investigations into desalination
Procedia Manufacturing, 2019 Abstract Water is essential to living organisms, yet only 0.02% of this natural resource is accessible as a direct source of fresh- and drinking water. South Africa, being a coastal country, is an ideal candidate for the use of treated sea water as an alternative source of fresh water.

Energy Science &Engineering, EarlyView.Three designs were built and tested: a single‐slope still, a six‐stepped still, and a six‐stepped still with 5 mm sponge sheets. The novelty lies in fixing porous sponge sheets to the vertical faces of the steps. Yield of freshwater and instantaneous efficiency were determined in various combinations, that is, base, stepped, and stepped‐cum‐sponge ...
