In this study, the efficiency of the resins, whose commercial name is IMAC HP-IIIE type strong acidic cationic resins, for removing hardness from water is investigated. For this purpose, water with hardness of 62, French unit was passed through 100 mi of the resin in a column at a rate of 80 ml/minute to obtain the breakthrough curve. This process was repeated two times after regenerating the resins at the end of the each run. Later, the experiment was continued in the same way using waters with 84 and 108 French hardness, respectively.
