Comparison of boron removal by ion-exchange resin in column and hybrid membrane process

Ion exchange is a major technique for boron removal from seawater using specific ion-exchange resins. The aim of this study was to compare two techniques using ion-exchange resins (column and hybrid ion-exchange microfiltration) for boron removal. For that, model boron solutions were used and ion-ex...

Description
Summary:Ion exchange is a major technique for boron removal from seawater using specific ion-exchange resins. The aim of this study was to compare two techniques using ion-exchange resins (column and hybrid ion-exchange microfiltration) for boron removal. For that, model boron solutions were used and ion-exchange resin with different size (unsieved, sieved at 500 and 600 μm, ground and sieved at 40 and 60 μm) for three commercial resins (Amberlite IRA743, Diaion CBR05, Purolite S108) in batch, column, and in an hybrid ion-exchange/microfiltration system. In batch, an important increase in kinetics was observed for smaller resins (40–60 μm and
