Procedure for treating aqueous salt currents, in particular saline effluents, by membrane distillation with previous treatments, to eliminate total calcium hardness and permanent calcium hardness and the presence of sulfates in saline effluents, more particularly in residual brines of desalination plants . The system allows brines to be concentrated above 37% by weight, that is, above saturation, which considerably reduces the volume of the brine, adapts it to other industrial uses and produces pure water. |
