With the rapid global industrialization and urbanization

ensuring continuous water supply and comprehensive water quality management has become a major challenge. Power plant cooling water consumption is significant

and to achieve zero discharge

many plants have adopted desalination measures to increase concentration ratios and enable water reuse. However

existing treatment technologies face high energy consumption

system complexity

and secondary pollution issues. To solve these problems

the application of electrochemical coupling pilot-scale equipment in cooling water treatment is experimentally studied

and the effects of electrochemical coupling pilot-scale equipment on scale removal

corrosion prevention and wastewater resource utilization are analyzed. The results show that

the equipment removes hardness and alkalinity significantly

and reduces conductivity and chloride ion content efficiently. Under conditions with voltage of 3.2 V and current of 240 A

the hardness removal rate reached the highest(5.15% and 55.77%

respectively)

and under conditions with current of 250 A and voltage of 3.2 V

the alkalinity removal rate reached the highest(36.96% and 91.41%

respectively). The electrochemical coupling technology offers clear economic advantages compared with the conventional methods

providing an efficient

eco-friendly

and cost-effective solution for cooling water treatment with broad application prospects.
