Abstract

Combined ion exchange (CIX) treatment of wastewater effluent and ion-exchange regeneration using flue gas carbon dioxide (CO₂) was investigated as a way of beneficially joining the water and energy sectors. CIX treatment removed calcium, magnesium, sulfate, nitrate, phosphate, and dissolved organic carbon from wastewater effluent. Regeneration of CIX using sodium chloride, sodium bicarbonate, hydrochloric acid, and CO₂ was investigated. Carbon dioxide had a lower regeneration efficiency compared with the other regeneration solutions. Alternative CO₂ regeneration conditions were evaluated to gain insight on the effects of increased gas pressure, increased contact time, and increased rate of CO₂ dissolution on regeneration efficiency.
