Abstract
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.
