The aim of this paper is to apply power ultrasound (pus) on the industrialized scale taking sugar industry as a representative selection of the industrialized application. The deposition of calcium sulfate in the evaporator bodies which is commonly known as scale costs billion of the economy. In fact, scale formation is considered as cancerous during sugar processing. This problem has received attention from several years, however, to date, there is no effective solution to get rid of this problem. The application of pus on an industrial scale during sugar processing is accompanied by a significant decrease in viscosity of mother liquors (molasses and massecuites) and increase in the heat transfer coefficient (HTC) of the evaporator bodies and finally overall increase evaporation intensity of the boiling house. The scanning electron microscopy (SEM) analysis of the calcium sulfate scale clearly illustrates that the pus treatment suppresses the formation of a thermodynamically least stable (soft polymorph) of the calcium sulfate. The observed results are consistent with the century-old Ostwal’s Repining Principle. The laboratory experiments coupled with the industrial trials are found confirmed to be beneficial for process control and significant energy saving during sugar processing. Additionally, use of chemicals declined significantly. The present study beyond doubts proves that the application of pus seems to be a potential alternative for its commercial application in the sugar industry. Moreover, pus equipment is easy to operate and has good performance in term of high continuity and optimization.
