  Characterization and Effects of Scale formation on Heat transfer system of Multiple-effect evaporator units in Cane sugar industry” is the title of my thesis work, the study has been conducted characterization of scale formation by collected scale samples from Wonji-Shoa Sugar Factory and characterized chemically to determine its composition and the scale was resulted 2604.70 mg/l composed of CaSO4 in the fourth body evaporator and 2860.66 mg/l in the fifth effect evaporators and minor amounts have been recorded in the other three effects. Additionally, process water has been characterized for their composition and pH which shows that process water is within a normal hardness and pH range. But the juice was abnormally high when compared to world average of 1.5% CaO % in juice. Therefore, the main cause of heat transferring units scaling in the plant was the CaSO4 content of the ..
