Abstract
Waste salts and brines are disposed of by constructing salt water solar pond power plants, concentrating the waste salts and brines, and then introducing them into the heat storage layers of the solar ponds of the power plants. The basins in which such solar ponds are constructed are made deeper than needed to sustain operation of the power plant at its designed output; and after a deep basin is filled, the concentrated brine from the heat storage layer is available to construct another solar pond which is then available for storing additional waste salts. In concentrating the waste salts, sodium chloride will precipitate; and this material can be deposited at the bottom of the solar ponds to seal the same against leakage.
