Description:
We studied the effect of water hardness, temperature and the nature of walls on CaCO"3 heterogeneous nucleation, which is the main condition of scale. The probability of CaCO"3 heterogeneous precipitation increased for weak water hardness and weak temperatures. The wall nature did not influence the precipitation kinetics for hard water and high temperatures, but it had an important effect on the type of nucleation. The determination of the precipitate scale amount following heterogeneous nucleation by means of a weighted method showed that plastic materials have a greater scaling susceptibility than metallic materials.
