Abstract

The invention relates to the disposal management of brines that are obtained from potash production and particularly contain salts and residues produced during potash and rock salt mining. In order to provide a relatively inexpensive solution that is reliable in the long run, a method is disclosed which comprises the following steps: a) the saline water (54) is collected; b) the saline water is sprayed using a plurality of spraying systems (62) that are mounted above a deposition surface (30A, 30B) in order to produce saline droplets which land, finely and evenly distributed across the entire area by the mass of air located above the deposition surface (30A, 30B), on the deposition surface (30A, 30B) after traveling along a certain convection section; c) said deposition surface (30A, 30B) being located outdoors. The disclosed disposal method for the waste waters is environmentally friendly, generates no noise or exhaust gases, is controllable, essentially uses only solar power, and consumes only very little external energy required for generating pressure.
