Ritter (1983) [45] conducted scaling tests for two salts, lithium
sulfate and calcium sulfate. He found that the scaling rates of the
different salts could be correlated using the following six parameters: super-saturation, mass transfer coefficient, surface temperature, sheer stress, heat flux, Reynolds number. Super-saturation was the most important parameter while the order of impacts of the
other parameters depends on the type of salts. Hasson (1981) [22]
listed three process conditions that lead to super-saturation andalso proposed the significant parameters which determine the super-saturation potential that causes precipitation fouling
