The Benefits Of Solar Distillation

Water as we all know is a very precious natural resource. One can stay about a month without food, but it's hard to survive for a week without water. This invaluable liquid constitutes about 60% of our body mass, 70% of our brain, and 80% of our blood. Although it covers one-third portion of our planet, only 3% is fresh water, and out of that only 1% is readily accessible for human use. One can make out from these facts and figures, how critical resource this water is. In this context, water needs to be conserved and, more significantly recycled or treated. It's not feasible to use less than usual quantity of water because it is required for both domestic and commercial or industrial activities. So, the practicable approach is to treat or purify

Unlike other forms of water purification it can turn salt or brackish water into fresh drinking water (i.e. desalination). The structure that houses the process is known as a solar still and although the size, dimensions, materials, and configuration are varied, all rely on the simple procedure wherein an influent solution enters the system and the more volatile solvents leave in the effluent leaving behind the salty solute behind.

Solar distillation differs from other forms of desalination that are more energy-intensive, such as methods such as reverse osmosis, or simply boiling water due to its use of free energy.

Advantages: A pond of saltwater with a clear lid takes advantage of solar heat. The saltwater evaporates and condenses on the lid. The brine stays in the pool and condensation forms potable

The raw water is sprayed onto tube bundles, which are heated on the inside by condensing steam. As a result of the transport of heat via the tube walls, part of the liquid film on the outside of the tube bundle evaporates. The resulting steam is used to heat the next effect (stage), where it again condenses on the inside of the tube bundle. The under pressure steam compressor, which is powered by medium- or low-pressure steam, extracts part of the steam created in the final effect for further compression. This condensed steam is then re-employed as a heat source for the first
