High voltage impulse (HVI) has gained attention as an alternate technique controlling CaCO3 scale formation fro water treatment. The effect of temperature and applied voltage of HVI on Ca<SUP>2+</SUP> concentration was studied in this study. As the applied voltage from 0 to 15kV and the temperature increased from 20 to 60℃, the Ca<SUP>2+</SUP> concentration decreased, indicating that the aqueous Ca<SUP>2+</SUP> precipitated to CaCO3. The Ca<SUP>2+</SUP> concentration decreased up to 81% under the condition of 15kV and 60℃. Rate constant for the precipitation reaction, k was determined under different temperlature and voltage. These results show that the HVI induction accelerates the precipitation to CaCO3, particularly much faster at higher temperature.
