Zusammenfassung:	Systems and methods for processing a highly saline brine containing monovalent and multivalent cations is disclosed. The systems and methods may include feeding the saline brine into a nanofiltration membrane at a high pressure effective produce a permeate having (1) a concentration of multivalent cations that is lower than saline brine and (2) a concentration of monovalent cations that is higher than the saline brine. L'invention concerne des systèmes et des procédés de traitement d'une saumure hautement saline contenant des cations monovalents et multivalents. Les systèmes et les procédés peuvent comprendre l'introduction de la saumure saline dans une membrane de nanofiltration à une pression élevée pour produire un perméat ayant (1) une concentration de cations multivalents qui est inférieure à celle de la saumure saline, et (2) une concentration de cations monovalents qui est supérieure à celle de la saumure saline.
