System Configuration

• Pretreatment System: Seawater booster pumps and self-cleaning filters remove large suspended particles and impurities from seawater, ensuring qualified feedwater quality for the electrolyzer.
• Electrolysis System: The electrolyzer serves as the core reaction unit, equipped with patented coated electrodes featuring excellent salt spray resistance and anti-corrosion performance, backed by a 5-year warranty.
• Storage System: Sodium hypochlorite solution generated through seawater electrolysis is temporarily stored in sodium hypochlorite storage tanks.
• Dosing System: Continuous dosing pumps and shock dosing pumps inject the finished sodium hypochlorite solution into the circulating water system.
• Auxiliary System: Acid cleaning unit, hydrogen venting unit, and cooling unit integrated with comprehensive safety interlock protection.
• Power Supply System: Rectifier transformer cabinet converts AC power into DC power for electrolysis reactions, with power consumption as low as 4.5 kWh/kg Cl₂.

Application Scenarios

• Coastal Power Plants / Nuclear Power Circulating Water Systems: Effectively inhibits the attachment of shellfish and algae, preventing pipeline blockage and biofouling corrosion.
• Offshore Platforms / Marine Ballast Tanks: On-site chlorine generation without hazardous chemical storage, meeting maritime environmental protection requirements.
• Ports / Terminal Water Treatment: Provides cooling water treatment and ballast water disinfection with long-lasting microbial growth control.
• Island / Coastal Industrial Park Water Disinfection: Utilizes locally available seawater resources to solve disinfectant transportation challenges in remote areas.
