Abstract

Den foreliggende oppfinnelse vedrører en fremgangsmåte for fremstilling av salt, omfattende de følgende trinn: (i) fremstilling av en vandig saltløsning inneholdende minst 100 g/l natriumklorid og minst 0,01 ppm polyvalente kationer ved oppløsning av en natriumkloridkilde i industrielt vann, (ii) tilsetning av en effektiv mengde av minst én positiv retensjonsforbedrende komponent til den vandige saltløsning, (iii) deretter underkastes oppløsningen for et nanofiltreringstrinn slik at oppløsningen separeres i et retentat som er anriket på de polyvalente kationer og et permeat som er den rensede vandige saltløsning, og (iv) permeatet konsentreres for å fremstille saltet. ?? ?? ?? ?? 1
