| description | In recent years, chemical water treatment equipment has gained significant attention due to its environmental-friendly features, multifunctionality, and broad applicability. Recognizing the limitations of existing chemical treatment equipment, such as challenges in scale removal and the high water content in scale deposits, we propose a novel drum design for both anode and cathode, enabling simultaneous scale suction and dehydration. We constructed a small experimental platform to validate the equipment's performance based on our model. Notably, under the optimal operating parameters, the hardness removal rate for circulating water falls within the range of 19.6–24.46%. Moreover, the scale accumulation rate per unit area and unit time reaches 13.7 g h−1 m−2. Additionally, the energy consumption per unit weight of the scale remains impressively low at 0.16 kWh g−1. Furthermore, the chemical oxygen demand (COD) concentration decreased from an initial 106.0 mg L−1 to a mere 18.8 mg L−1, resulting in a remarkable total removal rate of 82.26%. In conclusion, our innovative electrochemical water treatment equipment demonstrates exceptional performance in scale removal, organic matter degradation, and water resource conservation, offering valuable insights for future research and development in chemical treatment equipment and electrochemical theory.
