The turbidity of a fluid is reduced by adding a treatment solution containing a flocculation agent to said fluid. The treatment solution has a density different from that of the fluid. It is added at selected locations in the fluid such that the difference in densities will cause the treatment solution to be uniformly distributed throughout the fluid to be treated thereby causing flocs to be uniformly distributed throughout the fluid. In this way, a fluid can be treated in situ, rather than transported to a separate location, and mechanically mixed with a flocculation agent. This technique has particular application in the preparation and maintenance of solar ponds.

Method of and apparatus for reduction of turbidity in a body of fluid

Dusting of a solar pond having an upper wind-mixed layer is controlled by providing a vertically oriented drain on a downwind side of the pond. The drain has an upper, open, free-end spaced above the level of the surface of the pond in the absence of wind. When wind blows across the pond, surface water piles-up at the downwind side of the pond creating a hydraulic head relative to the open free end of the drain with the result that surface water and debris floating thereon are drawn toward and into the drain.
