Welcome to Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. – a professional manufacturer specializing in water treatment chemical dosing solutions. Our Liquid Chlorine Dosing System for Water Treatment Plants with Fully Automatic Control and Skid Mounted Design is engineered to deliver precise, safe, and efficient chlorine injection for disinfection and process water treatment. With years of manufacturing experience, we supply reliable systems to markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. This skid-mounted, fully automatic unit minimizes installation complexity and ensures consistent dosing accuracy, making it an ideal choice for municipal and industrial water treatment plants.
The system integrates a chlorine storage tank, dosing pump, flow meter, pressure gauge, automatic control panel, and all necessary valves and piping on a compact skid. It is pre-assembled and factory-tested, significantly reducing on-site installation time and risk of errors. The PLC-based control allows for seamless integration with existing plant SCADA systems, providing real-time monitoring and remote adjustment capabilities.
Key Features & Technical Specifications
Fully Automatic Control: PLC with touch-screen HMI for easy operation, automatic dosing based on flow or residual chlorine signal.
Skid Mounted Design: All components pre-mounted on a heavy-duty stainless steel frame, simplifies installation and relocation.
High-Precision Dosing Pump: Diaphragm or piston type, adjustable stroke length and frequency, accuracy ±1%.
Leak Detection & Safety: Integrated chlorine gas detector, emergency shut-off valve, and ventilation port for operator safety.
Corrosion-Resistant Materials: Wetted parts in PVC, PTFE, or PVDF; external piping in SS304/316L or FRP as per requirement.

Frequently Asked Questions (FAQ)
Q: What is the typical lifespan of the liquid chlorine dosing system?
A: With proper maintenance, the system can operate reliably for 10–15 years. Key components like pumps and seals may require replacement every 2–3 years depending on usage.Q: Can the system handle high chlorine concentrations (e.g., 12.5% sodium hypochlorite)?
A: Yes, the wetted parts are made of corrosion-resistant materials like PVC, PTFE, or PVDF, which are compatible with common liquid chlorine concentrations. Please specify your chemical when ordering.Q: Does the skid come with a built-in chlorine storage tank?
A: The system can be configured with an integrated storage tank (optional). Standard design includes a suction line for connection to a separate storage tank. Please discuss your layout with our engineers.Q: How difficult is the installation? Do you provide on-site assistance?
A: The skid-mounted design makes installation straightforward – just connect power, incoming water/chemical lines, and the injection point. We provide detailed manuals and remote support. On-site commissioning is available upon request at additional cost.Q: What safety features are included?
A: Standard safety features include a chlorine gas detector, emergency shut-off valve, low-level alarm, and overpressure protection. For hazardous areas, we can add explosion-proof components (ATEX/IECEx certification optional).Q: Can the control system be integrated with my existing SCADA?
A: Yes, the PLC supports common communication protocols like Modbus RTU, Profibus, and Ethernet/IP. We can also provide a custom interface for integration with your plant’s DCS.Q: What is the delivery time?
A: Standard units can be shipped within 30–45 days after order confirmation. Customized systems may require 45–60 days depending on complexity. We ship from Tianjin Port, and we can arrange logistics to your destination.Q: Do you offer spare parts or maintenance kits?
A: Yes, we provide a recommended spare parts list and can supply maintenance kits (e.g., pump diaphragms, seals, check valves) for the first two years of operation. Contact our after-sales department for details.
