Chronoamperometry Study Of The Inhibition Of Groundwater Scaling Deposits In Fourchi

AbstractFourchi groundwater supply for the city of Aïn M lila drinking water are very hard (76°F) because they are loaded into tartar, which consists mainly of calcium carbonate and its deposition in various industrial plants and networks distribution of water lead to many problems of a technical and economic as: -Desactivation of detergents and soaps by forming complexes with calcium ions. - Partial or total blockage of the pipes with lower river flows. -Lower heat transfer in the case of boilers. In this study we used the electrochemical method for accelerated scaling is based on the reduction of dissolved oxygen at a negative potential fixed (-1V) to study the effect of temperature and the effect of concentration of inhibitors K3PO4 and NaOH on power encrusting water. The study of the accelerated scaling curve has shown that these waters are scaling times of 20.3min at 20°C and 7.3min at 50°C. The effect of inhibitor is pronounced characterized by obtaining a straight line from 3.5mg/L K3PO4, 150mg/L of NaOH at 20°C. For tests at 50°C showed that the effect of temperature significantly reduces the time scaling at 20°C
