摘要: Boron removal in seawater desalination presents a particular challenge. In reverse osmosis (SWRO) systems boron at low concentration (<0.5 mg/L) is usually achieved by second pass using brackish water RO membranes. However, this process requires chemical addition and important additional investment, operation maintenance, energy costs. Electrocoagulation (EC) can be used to achieve such concentration. work, the of from aqueous solution was carried out EC aluminum iron electrodes. Several operating parameters on efficiency as initial pH, current density, ion concentration, feed gap between electrodes, electrode material, were investigated. case bipolar electrocoagulation (BEC), an optimum 96% corresponding final 0.4 mg/L density 6 mA/cm² pH = 8 The conc...
