... laboratory investigation shows that additives vary in performance depending on the type of mechanisms by which they function to control or retard scale formation. The enhanced maleates were found to be superior antifoulants compared to those currently available commercially. The enhanced maleate ...

Influence of water hardness, substrate nature and temperature on heterogeneous calcium carbonate nucleation
We studied the effect of water hardness, temperature and the nature of walls on CaCO3 heterogeneous nucleation, which is the main condition of scale. The probability of CaCO3 heterogeneous precipitation increased for weak water hardness and weak temperatures. The wall nature did not influence th ...
