Growth Period in Crystallization Fouling

In the present chapter, recent decade’s research on the crystallization fouling of calcium salts including calcium sulfate (CaSO4), calcium carbonate (CaCO3) and their combination were reviewed. The effects of the most important operational parameters affecting the formation of crystalline fouling such as flow velocity (u), fluid bulk temperature (Tb) and heat transfer surface temperature (Ts), salt concentration, applied heat flux (HF), and pH were categorized from various papers. The effects of these parameters were explained in the fouling growth period. Our goal is to create general ideas among crystallization fouling research and to identify the effects of various factors on this type of fouling. In addition, it is tried to show the strengths and weaknesses of the previous researches and the possibility of creating new research areas.
