Solar evaporation is a natural process where water is heated by the sun, causing it to turn into vapor. This method is commonly used to extract salt from seawater or to concentrate brine solutions. As the water evaporates, it leaves behind solid minerals, which can then be collected. This technique is often employed in areas with high temperatures and low humidity, making it efficient for large-scale operations. Solar evaporation ponds are designed to maximize sunlight exposure, allowing for faster evaporation rates. This sustainable method is environmentally friendly and requires minimal energy input compared to other evaporation techniques.
