Seawater or brine is fed into an electrolyzer with rated current for electrolytic reactions (cathodic, anodic, hydrolysis), producing sodium hypochlorite (target) and hydrogen. The power supply provides DC current, a must-have. Sodium hypochlorite disinfects water, sewage, tableware, etc., inhibits algae, treats wastewater, reduces BOD, and more. The power supply uses soft-switching and PWM tech, with high efficiency, stable output, and full protection.
