摘要：
In order to explore the electrochemical water softening characteristics under pulsed electric field, Three important factors including solution hardness, frequency of high frequency pulse power supply and duty cycle were studied, and the effects of single factors on water softening efficiency and its combined effects on electrochemical water softening were investigated and optimized. The results show that the hardness of solution has the most obvious effect on electrochemical water softening, and the effects of the three factors are in order of hardness > duty cycle > frequency. At 36 V and initial concentration of 300-400 mg-L-1, the electrochemical reaction and deposition reaction reached the best synergistic state. The change of duty cycle of power supply has no effect on the composition of CaCO3 crystal, but affects its nucleation and crystal growth processes. © 2023 Zhejiang University. All rights reserved.
