The CaCO 3 precipitation occurs both in solution and on walls of HDPE. By the weighing method, it is shown that the deposit mass increases with hardness and temperature.
WebOct 1, 2024 · When calcium ions from the solution precipitate in the form of calcium carbonate at the cathode, the concentration of scaling calcium in the solution decreases. Hence, other surfaces in contact with the solution are protected against scaling, while the cathode acts as a sacrificial material [ 2, 6]. WebAbstract. Scaling of calcium carbonate (CaCO3) is commonly found in piping systems in oil, gas, desalination and other chemical processes. The scale may create technical …
