Abstract: Softening of limestone for very hard water treatment is usually applied as a conventional water treatment process for domestic use. However, for industrial use, this treatment does not apply because it requires an increment in time for the precipitation of magnesium and calcium. In this research, an investigation of the efficiency of electrolysis process applied firstly, process conducted with hard water only and secondly with an alkaline chemical dosing to remove non-carbonated hardness of hard water. Results indicates that the production of primary coagulant during electrolysis increase the precipitation of CaCO3 and Mg (OH)2. The overall rate of removal of this process is 70% which is less for 6 times than the time required for conventional wastewater treatment method.
