Abstract: The present disclosure includes systems and methods for enhancing evaporation rates of a fluid, such as fluid including dissolved solids (e.g., a wastewater pond). In one example, a system includes a pump configured to pressurize air and an agitation assembly fluidly coupled to the pump, where the agitation assembly is configured to emit an air stream that impacts a top surface of the fluid body to generate droplets.

Abstract: A system for enhancing evaporation from a body of liquid, in which heated or unheated air is distributed through a pipe network that is submerged in the evaporation pond, with the air being injected into the pond to produce air bubbles in the water. The air may be combined with water prior to the injection. The water may be drawn from the pond. The air and/or water may be heated by solar heating, electric heating, fuel burning, or waste heat recovery. In the case of solar heating, any of a transpired solar collector, a packed bed solar collector, a flat plate solar collector, a linear Fresnel collector, a parabolic solar collector, a paraboloid dish solar collector, or other could be used. The pipe network may be maintained at a desired depth below the upper surface of the pond by various means, with one example being flotation devices, from which the pipe network is suspended.
