ABSTRACT:
Water in a solar pond power plant is chlorinated in order to help maintain the transparency of the wind-mixed layer, to suppress microbial activity at all levels of the pond, and to reduce fouling of the boiler which receives hot brine from the heat storage layer of the pond. In one aspect of the invention, chlorine is injected into the water in the wind-mixed layer, in the halocline, and/or in the heat storage layer. Injection into the wind-mixed layer and into the heat storage layer is possible by reason of the flow of this water outside the pond to supply the boiler and condenser of the power plant, thus providing accessibility to liquid chlorine treatment. The halocline is chlorinated by using vertically adjustable intake and discharge diffusers positioned in the halocline and exchanging the water in a stratum. In a second aspect of the invention, in-situ electrolysis is utilized for selectively chlorinating the pond at various levels or locations.
