Abstract
Water evaporates from a thin film, which can be developed over the surface of soil/water slurries, at a rate as much as 30 times that of the normal pan evaporation rate in a given locale. Utilizing this discovery, a slurry having suspended solid particles which are heavier than water are placed in a shallow lagoon. The slurry is then periodically agitated through its entire profile. This agitation is repeated as often as either the formation of a dry surface appears over the lagoon or, alternatively, a noticeable clear water skin forms over the suspended solids of the slurry. By the expedient of sequentially repeating the agitation, evaporation of water present in the slurry can occur at a rate on the order of 30 times the normal pan evaporation rate of a given locale.
