Abstract

La presente se refiere a un procedimiento de separación y recuperación de metales alcalinos que incluye: permear y separar agua bruta que contiene un metal alcalino e iones divalentes usando una membrana de nanofiltración para obtener un permeado y un concentrado; y recuperar al menos parte del metal alcalino contenido en el permeado, en el que los iones divalentes contenidos en el concentrado se eliminan para obtener de ese modo agua sin iones divalentes en la que una proporción de una concentración en peso del metal alcalino en términos de los iones del mismo a una concentración en peso de los iones divalentes es mayor que la proporción en el concentrado, y al menos parte del agua sin iones divalentes se recicla al agua bruta. Reivindicación 7: Un aparato de separación y recuperación de metales alcalinos que comprende: una unidad de membrana de nanofiltración para permear y separar agua bruta que contiene un metal alcalino e iones divalentes usando una membrana de nanofiltración para obtener un permeado y un concentrado; una unidad de recuperación para recuperar al menos parte del metal alcalino contenido en el permeado; y una unidad de eliminación de iones divalentes para eliminar al menos parte de los iones divalentes contenidos en el concentrado, en el que al menos parte de agua sin iones divalentes obtenida en la unidad de eliminación de iones divalentes se recicla al agua bruta.This refers to an alkali metal separation and recovery process that includes: permeating and separating raw water containing an alkali metal and divalent ions using a nanofiltration membrane to obtain a permeate and a concentrate; and recover at least part of the alkali metal contained in the permeate, in which the divalent ions contained in the concentrate are removed to thereby obtain water without divalent ions in which a proportion of a concentration by weight of the alkali metal in terms of the ions thereof at a concentration by weight of the divalent ions is greater than the proportion in the concentrate, and at least part of the water without divalent ions is recycled to the raw water. Claim 7: An alkali metal separation and recovery apparatus comprising: a nanofiltration membrane unit for permeating and separating raw water containing an alkali metal and divalent ions using a nanofiltration membrane to obtain a permeate and a concentrate; a recovery unit to recover at least part of the alkali metal contained in the permeate; and a divalent ion elimination unit to remove at least part of the divalent ions contained in the concentrate, in which at least part of water without divalent ions obtained in the divalent ion elimination unit is recycled to the raw water.
