PROCESS FOR TREATING WATER AND EFFLUENTS BY ULTRAFILTRATION AND ELECTROLYSIS, AND APPARATUS THEREFOR

摘要

Disclosed are a process and apparatus for the treatment of such fluids as water and effluents by ultra-filtration and electrolysis, useful in particular for the continuous recovery and separation of metallic cations from diluted solutions of their salts and to the softening of water. The apparatus comprises a casing, an ultra-filtration membrane separating the casing into two compartments; a cathode and an anode are respectively housed in two inner compartments separated by an ultra-filtration membrane. The cathodic compartment is connected to an inlet and to an outlet for fluid to be treated, while the anodic compartment is connected to an outlet for the permeate.
