READ MOREEvaporation happens when a liquid turns into a gas. It can be easily visualized when rain puddles "disappear" on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor.. Evaporation happens on a global scale. Alongside condensation

READ MORESolar-thermal water evaporation is a process in which liquid water changes from the liquid phase to the gas phase under the excitation of solar photons, and the high temperature generated accelerates the evaporation of water several times. In the natural environment,
READ MOREEvaporation is the process that changes liquid water to gaseous water (water vapor). Water moves from the Earth''s surface to the atmosphere via evaporation. Evaporation occurs when energy (heat) forces the bonds that hold water molecules together to break. When you''re boiling water on the stove, you''re adding heat to liquid
READ MOREEvaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water.

The untreated water absorbs heat, slowly reaching high temperatures. The heat causes the water to evaporate, cool, and condense into vapour, leaving the contaminants behind.
