Abstract

La presente se refiere a un procedimiento de separación y recuperación de metal alcalino que incluye: separar permeado que contiene un metal alcalino de agua sin procesar que contiene el metal alcalino mediante el uso de una membrana de nanofiltración; y la recuperación del metal alcalino contenido en el permeado mediante un pos-tratamiento, en el que se añade agua de dilución al agua sin procesar, seguido por el suministro a una unidad de membrana de nanofiltración que incluye la membrana de nanofiltración.This refers to an alkali metal separation and recovery process that includes: separating permeate containing an alkali metal from unprocessed water containing the alkali metal by using a nanofiltration membrane; and the recovery of the alkali metal contained in the permeate by post-treatment, in which dilution water is added to the unprocessed water, followed by delivery to a nanofiltration membrane unit that includes the nanofiltration membrane.
