Abstract
Proceso para actualización de plantas de tratamiento de efluentes de procesos de producción de pulpa y papel, donde se remueven sales del efluente para reutilización del agua y recuperación de químicos. Comprende un primer sistema de diálisis para remover sales, un segundo sistema de tratamiento para recuperación o re-concentración y un post-tratamiento del re-concentrado. El primer sistema es una etapa de electrodiálisis reversible o reversible pulsada, separando las sales del efluente, enviadas al segundo sistema para concentrar las sales o transformarlas en químicos, esto último con electrodiálisis con membranas bipolares o metátesis, corriente tratada con secado spray, cristalización o evaporación.
