The present work was aimed at electric energy obtaining by mixing coal-mine brine with low-salinity water utilizing reversed electrodialysis (RED). The electrodialytic unit equipped with alternatively arranged cation and anion exchange membranes, was mounted in-between two Pt-coated electrodes. The

The electrodialytic removal of boron from seawater reverse osmosis permeate was examined in laboratory. Two model SWRO permeates were investigated. The composition of the first one (TDS 604 mg/L, B content 2.25 mg/L) was calculated using ROSA 6.0 software (DOW Chem.) assuming SW30HR-320 membrane, oc

Both pressure driven and electro-membrane processes show better boron removal efficiency when carried under alkaline conditions when the boric acid is ionized to a large extent. Even under such conditions the electrodialysis (ED) performance is, however, reported to be poor since low boron current e

Presently boron-rich chemical landfill leachate originating from Tarnowskie Góry is being treated by boronselective ion-exchange resin. Since the boron concentration in this feed water type is relatively high (approx. 70 mg of B/L), the IE column post-regeneration lyes, that are strongly acidic and
