Chemical Study Of The Effect Of Fruit Peel On The Treatment Of Hard Water

Abstract
Hard water contains many ions of calcium, magnesium and bicarbonates, which spontaneously form compact and adherent deposits in domestic and industrial installations [1]. The treatment of hard waters has been in the interest of several works in order to reduce the negative consequences of the tartar. Our study concerns the softening of Bounouara hard water having a hardness of 60°F in the presence of Punica granatum peel as a natural, food and ecological inhibitor. On the other hand, on the valorisation and disposal of Punica granatum peels that are considered waste. The evaluation and inhibition of hard water scaling of Bounouara and the monitoring of the growth germination phenomenon during the formation of the calcium carbonate deposit were carried out by the use of the rapid controlled precipitation method. The plotting of the PCR curves obtained from the raw waters of Bounouara with respect to the waters treated with different concentrations of Punica granatum peel shows that there is a delay in the formation of calcium carbonate scale by measuring pH and resistivity as a function of time from a concentration of 0.025 g/L and the total blockage of the precipitation is carried out at 0.25 g/L of addition of Punica granatum peel.
