AB  - 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 CaCO<sub>3</sub> and Mg (OH)<sub>2</sub>. 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.
