Paper Title
Impedancemetric Study Of Inhibiting Effect Of Natural Product On Hard Growth Water

Abstract
Hard water form compact and adherent deposits to the walls of pipes and industrial or domestic installations [1] causing enormous technical and economic problems, in the factory constructions, agronomic and the domestic equipment (valves, taps and boilers). Therefore, it is very important to establish a treatment of Algerian hard ground waters in order to reduce their hardness and exploit them. Bounouara drilling is one of the important water resources that feed the south east of city of Constantine with drinking water and even water for industrial and agronomic settlements. But the great inconvenience of Bounouara water is very high hardness which is in the order of 60°F. Several works have been done to inhibit the hardness but all the inhibitors that were used are chemicals that have an adverse effect on health, that's why all the chemical inhibitors are used only for industrial water treatment. In this work, we used citrus bark as natural and ecological inhibitors to reduce the scaling power of Bounouara water and to prepare drinking water on the one hand, and valorize waste of two citrus barks on the other hand. The evaluation of chemical treatment effect of hard water of Bounouara was carried out by impedances measurement of the deposits of calcium carbonate electrolyte interface [2, 3].
