Removal and recovery of boron from geothermal wastewater by selective ion exchange resins. I. Laboratory tests

Abstract

Boron removal from wastewaters of geothermal plant was studied using N-glucamine type chelating resins so-called Diaion CRB 01, Diaion CRB 02, Purolite S 108. The batch-mode sorption studies was performed to obtain the optimum amount of resins for boron removal from geothermal wastewater. The boron on the resin was quantitatively eluted with 5% H 2SO 4. A column-mode study was performed using weak base ion exchange resin Diaion WA 30 for the separation of boron from H 2SO 4 solution.
