Process of Concentrating of Highly Mineralized Waters in an Air-Gap Membrane Distiller

Resumo

The membrane distillation process for the concentration of highly saline waters using air-gap distillation apparatuses equipped with Russian-made membranes has been studied. It has been shown that the proposed approach provides a fourfold increase in the concentration of solutions with the simultaneous production of fresh water that is suitable at least for technical needs. The results obtained may be of interest for concentrating water of various origins.
