Sodium Hypochlorite Equipment for Industrial Wastewater Treatment Fully Automatic Control
Product Spotlights
Welcome to Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd., a professional manufacturer specializing in water treatment solutions. Our Sodium Hypochlorite Equipment for Industrial Wastewater Treatment is designed with fully automatic control to deliver reliable, cost-effective disinfection for a wide range of industrial applications. By producing sodium hypochlorite on-site from common salt, this system eliminates the risks of handling and storing hazardous chemicals, while ensuring consistent chlorine dosing for your wastewater treatment process.
Built with advanced PLC technology, our equipment offers seamless operation and minimal human intervention. Whether you are treating effluent from chemical plants, food processing facilities, or municipal wastewater, this system provides a safe and sustainable solution. Below, we detail the key features, technical specifications, and benefits that make our equipment a preferred choice for industrial clients worldwide.
Key Features
Fully Automatic Control – Equipped with a PLC and HMI touch screen, the system automatically adjusts production based on real-time demand, reducing operator workload and human error.
On-Site Generation – Uses common salt (NaCl) and electricity to produce sodium hypochlorite (NaClO) with a concentration of 0.5%–1.0%, which is safer and more economical than purchasing commercial bleach.
Robust Construction – Made from corrosion-resistant materials such as FRP, PVC, and titanium electrodes, ensuring long service life even in harsh industrial environments.
Low Operating Cost – Only requires salt and electricity; no need for transportation, storage, or handling of dangerous chemicals. Typical cost savings of 30%–50% compared to bulk chemical purchases.
Compact Skid-Mounted Design – Pre-assembled on a steel frame, the system is easy to install and requires minimal footprint. Options for containerized units are available for outdoor or remote locations.
Remote Monitoring & Alarms – Capable of remote communication via Ethernet or GSM, allowing operators to monitor performance and receive alerts on their mobile devices.
Safety Features – Includes leak detection, automatic shutdown in case of abnormal conditions, overpressure protection, and emergency stop button.

Cost Efficiency – Lower operational costs compared to purchasing commercial sodium hypochlorite. The system pays for itself within 12–18 months for most industrial users.
Environmental Compliance – Helps meet stringent discharge regulations by providing consistent disinfection without generating harmful byproducts (e.g., chlorates).
Ease of Operation – The fully automatic control reduces the need for skilled operators. The system can be integrated with existing SCADA or DCS networks.
Reliable Performance – Built with high-quality components from reputable suppliers, our equipment is designed for 24/7 continuous operation with minimal downtime.
Frequently Asked Questions (FAQ)
Q1: What raw materials are needed to operate this equipment?
A: The system uses common salt (sodium chloride) and electricity. A soft water supply is recommended to prolong electrode life. The salt does not need to be high-purity; industrial grade is sufficient.
Q2: How long does it take to install and commission the system?
A: Typical installation and commissioning take 3–5 working days for a standard skid-mounted unit. Our technical team can provide on-site support or remote guidance.
Q3: What is the lifespan of the electrodes?
A: The titanium electrodes coated with mixed metal oxides generally last 3–5 years under normal operating conditions. Replacement is simple and cost-effective.
Q4: Can the system be integrated with existing wastewater treatment plants?
A: Yes, our equipment is designed with standard industrial communication protocols (Modbus, Profibus, etc.) and can easily interface with existing control systems. We provide customization options for specific requirements.
Q5: What is the required maintenance?
A: Routine maintenance includes periodic cleaning of the electrolytic cell, checking the brine filter, and calibrating the chlorine analyzer. The system includes self-cleaning functions to reduce manual effort.
Q6: Do you offer after-sales service and spare parts?
A: Absolutely. We have a dedicated after-sales team and stock commonly used spare parts. Our warranty covers 12 months from date of commissioning, and extended service contracts are available.
Q7: Can the equipment handle variable flow rates in wastewater treatment?
A: Yes, the fully automatic control system adjusts chlorine production based on the flow rate and chlorine demand signal from the analyzer. This ensures optimal dosing and avoids overdosing.
