Influence Of Copper And Zinc On The Power Furring Of Encrusting Water

AbstractIn calcareous soils, the underground water of Hamma carry significant concentrations of calcium hydrogencarbonate. For a content of 59 ¡ F waters were very hard and out have to be in a treated softening way or decarbonation before the use, because lead to phenomenes of scaling. The precipitation of an insulating layer of calcium carbonate on the walls of the water distribution have serious consequences technique and economic. In this work we studied the effect of copper and zinc on the precipitation of calcium carbonate by using the test of rapid controlled precipitation (RCP) and scaling tests on polyethylene. The test of rapid precipitation controlled in the presence of metal cations (Cu, Zn) at low concentrations (0.5mg/L of Cu2+, 0.15mg/L of Zn2+), retarted the precipitation of calcium carbonate.The test of scaling on polyethylene in the presence of Cu and Zn reached an efficiency of 100%. This reflects the pronounced inhibitory effect of these ions
