This article describes water purification with the use of solar energy and molten salt. The article describes a theoretical water purification systems which use both solar energy and molten salt. Molten salt is a eutectic mixture of sodium nitrate and potassium nitrate. This combination produces a substance with a lower melting point than its constituents. The main use of molten salt is to store the solar energy in the form of heat. This is useful since solar energy will be absent when the sun goes down. Here’s a small overview of the system: The first step is to heat up the molten salt which the use of solar power, once the molten salt is heated up to a high enough temperature, the contaminated water is boiled to produce steam. The contaminated water is being boiled through the use of transferring heat from the molten salt to the contaminated water. The steam produced from the water will go towards a condenser. Inside the condenser, the steam is reverted back to its liquid state through heat exchange. The water collected from the steam will be a clean water. Overall the use of molten salt in the purification of water is useful to improve the thermal processes. This article might be useful since it provides a means to purify water through the use of solar energy and molten salt.
