To maintain efficiency of heat exchanger, fouling of heat transfer surface is important to remove. This study was to investigate cleaning result of plate heat exchanger using ceramic ball. The fouling is created in heat transfer surface of plate heat exchanger using CaCO₃ as the fouling subject. The fouling concentration varied from 10 mol/m³ to 20 mol/m³. The overall heat transfer coefficient recovered 97.9% for 10mol/m³ case, and 94.3% for 20 mol/m³ case in comparison with initial state. It can be concluded that the cleaning of ceramic ball contribute significantly to the of performance recovery for overall heat transfer coefficient and fouling resistance after cleaning experiment.
