Electrodeposition of Calcium Carbonate and Magnesium Carbonate from Hard Water on Stainless-Steel Electrode to Prevent Natural Scaling Phenomenon

This study focuses on preventing scale formation in hard waters by controlled electrode-position of Ca2+ and Mg2+ a stainless-steel cathode at constant applied current intensity. The influence the anode material, BDD or Ti/Pt/PbO2, active area, stirring speed, anodic intensity inorganic carbon (IC), Ca2+, removal was investigated. Assays were performed with model water solutions, simulating Bounouara (Algeria) water. scaling inhibiting properties treated followed measuring IC, calcium, magnesium concentrations chronoamperometric characterization solutions. Ca/Mg molar ratio electrolysis also evaluated, utilizing solutions different compositions. It found that an increase speed geometric area favors IC rates. varied from 0.025 to 0.5 A, best results obtained for 0.1 either removals accelerated tests. However, energy costs current. deposit formed over does not seem posterior deposition rate, after eight consecutive assays, solid rate kept constant. influences increases it. showed hard-water phenomena can be prevented electrodeposition
