Sodium Hypochlorite Generator Producing 5%-15% Solution With Less Energy and Salt Input
Product Spotlights
As a leading manufacturer from Tianjin, China, Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. is proud to present our advanced Sodium Hypochlorite Generator designed to produce a 5% to 15% sodium hypochlorite solution with significantly lower energy and salt consumption compared to conventional electrolysis systems. Our system integrates cutting-edge electrode technology and intelligent control, ensuring stable operation, minimal maintenance, and consistent output quality. Whether you need on-site chlorination for water treatment, disinfection, or industrial processes, this generator offers a safe, cost-effective, and environmentally friendly alternative to purchasing commercial bleach.
The core principle of our generator is electrolysis of a brine solution (sodium chloride + water) to produce sodium hypochlorite. By optimizing the cell design and using high-efficiency titanium MMO (mixed metal oxide) electrodes, we achieve a high conversion rate with minimal energy input. The system is fully automated, with a PLC control unit that monitors parameters such as brine concentration, temperature, flow rate, and current density, ensuring the output solution is consistently within the desired concentration range. Our unique patented design reduces salt consumption by up to 30% compared to traditional generators, resulting in lower operating costs and less waste brine discharge.
Key Features & Technical Specifications
High Efficiency Electrolysis: Uses advanced MMO electrodes with long service life (typically 5-8 years) and low voltage drop.
Adjustable Concentration: Output solution concentration can be set between 5% and 15% via the control panel, meeting different application needs.
Low Energy Consumption: Typical DC power consumption is only 3.5-4.5 kWh per kg of active chlorine (depending on concentration and temperature).
Low Salt Consumption: Requires only 2.5-3.5 kg of salt per kg of active chlorine, significantly lower than industry average.
Automatic Operation: PLC with HMI touch screen provides real-time monitoring, data logging, and alarm functions. Can be integrated with remote monitoring (optional).
Compact & Modular Design: Skid-mounted or containerized options available for easy installation and expansion.
Corrosion-Resistant Materials: All wetted parts are made of titanium, PVC, or stainless steel to withstand harsh chemical environments.
Safety Features: Built-in hydrogen gas venting, over-temperature protection, over-current protection, and leak detection.

Our sodium hypochlorite generator is designed for a wide range of applications including municipal water disinfection, wastewater treatment, swimming pools, industrial cooling water, food processing, and agricultural irrigation. The on-site generation eliminates the hazards of transporting and storing bulk sodium hypochlorite, reduces chemical costs, and provides a consistent supply of disinfectant. Compared to chlorine gas, it is safer to operate and does not require special handling permits in many regions.
We also offer customized solutions to meet specific capacity, automation, and integration requirements. Our engineers can design a complete system including brine preparation, filtration, storage, and dosing pumps. Optional features include remote monitoring via IoT, automatic descaling cycles, and a backup power interface.
Tianjin ZhuoLiNeng Technology Co., Ltd. has been manufacturing water treatment equipment for over 15 years, exporting to North America, South America, Europe, Africa, Southeast Asia, Oceania, the Middle East, and many other regions. Our products are trusted by municipalities, industrial plants, and commercial facilities worldwide. With a dedicated R&D team and strict quality control, we ensure each generator undergoes rigorous testing before shipment from Tianjin Port. We provide comprehensive after-sales support, including spare parts, technical documentation, and online troubleshooting. Choose ZLN for reliable, efficient, and cost-effective on-site chlorine generation.
Frequently Asked Questions
Q: What is the typical lifespan of the electrodes?
A: The MMO electrodes have a service life of 5-8 years under normal operating conditions, depending on the salt quality, current density, and maintenance schedule.Q: Can the generator produce a 12% concentration?
A: Yes, the system is designed to adjust the concentration between 5% and 15%. You can set the desired value via the control panel, and the PLC will automatically regulate the current and brine flow.Q: How much salt and electricity are needed per kilogram of active chlorine?
A: Typically, 2.5-3.5 kg of salt and 3.5-4.5 kWh of electricity are required per kg of active chlorine, depending on the concentration and water temperature.Q: Do you provide installation and commissioning service?
A: We offer online technical guidance and on-site commissioning support (travel expenses to be covered by the buyer). Detailed manuals and video tutorials are also provided.Q: What is the minimum order quantity?
A: Our MOQ is one unit. However, we offer discounts for bulk orders. Please contact our sales team for a customized quotation.Q: Can the generator be used with seawater?
A: Yes, our system can be configured to use seawater (filtered) as the brine source. However, we recommend using fresh water with dissolved salt for better control and reduced electrode scaling.Q: What maintenance is required?
A: Regular inspection of electrodes for scaling, cleaning of the electrolyte cell, and checking of brine filters. The PLC system will alert you when maintenance is needed. We recommend a descaling cycle every 3-6 months.Q: Is the generator safe for unattended operation?
A: Yes, the system is fully automated with multiple safety interlocks. It can operate unattended, but we recommend periodic checks. The PLC will automatically shut down in case of abnormalities.
