Welcome to Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. As a professional manufacturer with certification, we are proud to introduce our Electrolytic Seawater Chlorination System for Marine Ballast Water Treatment – a solution designed to reduce operational costs while ensuring full compliance with international ballast water discharge standards. Unlike traditional chemical injection methods, our system generates active chlorine on-site from seawater itself, eliminating the need for costly chemical storage and transportation. This innovative approach not only simplifies logistics but also provides a more consistent and reliable disinfection process, making it the preferred choice for vessel owners looking to optimize their ballast water management.
Our system leverages advanced electrolytic cell technology to convert seawater into a potent biocide, effectively neutralizing invasive aquatic organisms and pathogens in ballast water. The entire process is fully automated, requiring minimal operator intervention and reducing the risk of human error. With years of experience in marine equipment manufacturing, ZLN has engineered this system to be robust, durable, and easy to maintain, ensuring long-term reliability even in harsh marine environments. Below, we provide a detailed overview of the system’s key features, technical specifications, and the tangible benefits it brings to your fleet.
▶ Key Features & Technical Specifications
On-Site Chlorine Generation: Uses electrolysis to produce sodium hypochlorite from seawater, eliminating the need for bulk chemical supply.
High Disinfection Efficiency: Achieves up to 99.99% reduction of bacteria, viruses, and marine organisms in ballast water.
Compact Modular Design: Space-saving footprint, ideal for retrofitting on existing vessels or new builds.
Fully Automatic Control: PLC-based system monitors flow rate, salinity, temperature, and chlorine concentration, adjusting output automatically.
Low Energy Consumption: Optimized electrode design reduces power usage compared to conventional electrochlorination units.
Durable Titanium Electrodes: Coated with mixed metal oxides (MMO) for long service life and minimal maintenance.
Seawater Compatibility: Designed to operate in varying salinity levels (10–35 ppt) and temperatures (0–40°C).
Comprehensive Safety Features: Built-in alarms, automatic shutdown on abnormal conditions, and corrosion-resistant materials.

▶ Advantages & Customer Benefits
Cost Savings: By generating chlorine on-site, you eliminate recurring expenses for purchasing, storing, and handling hazardous chemicals like sodium hypochlorite or chlorine gas. Additionally, lower energy consumption reduces electricity bills.
Regulatory Compliance: Meets IMO D-2 Ballast Water Performance Standard and US Coast Guard (USCG) requirements (depending on configuration – please consult with our team).
Minimal Maintenance: Self-cleaning electrode design and automatic backwashing system reduce cleaning frequency. Routine inspection is straightforward.
Environmentally Friendly: No external chemicals introduced into the marine environment; the residual chlorine quickly degrades into harmless salt and water.
Scalability: Modular architecture allows you to start with a smaller unit and add capacity as your fleet expands.
Reliable Performance: Hundreds of successful installations worldwide, with robust construction to withstand vibration and corrosion on board.
Our electrolytic seawater chlorination system is engineered to deliver consistent disinfection performance across a wide range of operating conditions. The PLC-based controller continuously monitors key parameters, ensuring stable chlorine output even when seawater salinity or temperature fluctuates. This intelligent system also logs historical data for compliance reporting, saving you time during port state inspections.

❓ Frequently Asked Questions
-
Q: How does this system compare to UV-based ballast water treatment?
A: UV systems require high turbidity and low particle load for effective disinfection. Our electrochlorination system works effectively even in high turbidity waters because the active chlorine penetrates particulates. Additionally, electrochlorination often has lower operational costs in saline water and provides a residual disinfectant effect, preventing regrowth during ballast hold time.
-
Q: What is the expected lifetime of the electrodes?
A: Under normal operating conditions (salinity 10–35 ppt, proper maintenance), the titanium MMO electrodes typically last 8–10 years. Regular cleaning cycles programmed into the controller help extend their life.
-
Q: Can this system be retrofitted onto existing vessels?
A: Yes. The modular design allows flexible installation in the engine room or dedicated ballast treatment area. Our team provides retrofitting guidance, and we can customize the layout to fit your space constraints.
-
Q: Does the system require any chemicals to be added?
A: No. The only consumable is seawater itself, and the system produces the disinfectant on-site. This eliminates the need to store and handle hazardous chemicals on board.
-
Q: What certifications does the system hold?
A: Our manufacturing facility is certified. The system is designed to comply with IMO D-2 standards and can be configured for USCG type approval (please inquire for specific model documentation). Additional classification society certificates (e.g., ABS, DNV, Lloyd’s) are available upon request.
-
Q: How much maintenance is required?
A: Routine maintenance is minimal – the system automatically performs self-cleaning cycles. Scheduled inspections every 3–6 months involve checking electrode condition, cleaning filters, and verifying sensor calibration. Our technical manual provides detailed procedures.
-
Q: What is the power consumption for a typical system?
A: Power consumption depends on flow rate and chlorine demand. For a 500 m³/h system, typical power draw is around 15–25 kW. We provide an energy efficiency report with each proposal.
-
Q: Can your system handle varying salinity, such as in brackish waters?
A: Yes. Our system is designed to operate effectively across a salinity range of 10–35 ppt. The PLC automatically adjusts current and flow rate to maintain optimal chlorine production efficiency.
