Characterization Of Calcareous Deposits In Ground Water By Impedance Technique And Fast Controlled Precipitation Method

The calcium carbonate deposits which are observed on surface of the drains of the industrial facilities and domestic involve serious consequences. The consequences of these deposits are mainly of three types: hydraulics by obstruction partial or total of the conduits, thermals because of their bad coefficient of thermal transfer and mechanics.Various methods have been developed in order to estimate the scaling propensity of natural waters, electrochemical methods, thermal or chemical methods. This study investigate the influence of two scale inhibitors K₂HPO₄ and K₃PO₄, introduced in Hamma hard water, on the calcareous deposit formation, which is monitored by electrochemical impedance spectroscopy (EIS) and Fast controlled precipitation method (FCP). The deposits formed are analyzed by X-ray diffraction and Raman spectroscopy analyses.
