Tianjin ZhuoLiNeng (ZLN) Technology Co., Ltd. is a professional manufacturer of chemical dosing and treatment equipment. Our Hydrochloric Acid Equipment is designed specifically for wastewater treatment plants requiring safe, precise and automated dosing of hydrochloric acid (HCl) at concentrations ranging from 5% to 15%. The system is fully automatic, skid mounted and plug-play, offering a compact and reliable solution for pH adjustment, neutralization and chemical cleaning processes. With a strong focus on operational safety and efficiency, this equipment simplifies the handling of corrosive chemicals while ensuring accurate dosing performance.
Key Features at a Glance
Fully Automatic Operation: The system is equipped with PLC-based controls, automatically regulating acid flow based on real-time pH signals from the treatment process.
Skid-Mounted Design: All components including tanks, pumps, valves, and instrumentation are pre-assembled on a sturdy steel skid for easy transportation and installation.
Plug-Play Installation: Simply connect the inlet and outlet lines and power supply; the unit is ready to run, reducing on-site installation time and cost.
Handles 5%-15% HCl: Engineered to safely store and dose hydrochloric acid solutions within this concentration range, making it versatile for various wastewater applications.
High Chemical Resistance: Wetted parts are made of corrosion-resistant materials such as PVDF, PTFE, and Hastelloy to extend service life.
Safety Interlocks: Includes leak detection, overpressure protection, and emergency shut-off systems to protect operators and the environment.
The equipment is ideal for municipal and industrial wastewater treatment plants where precise pH control is essential. It ensures continuous and stable dosing even under fluctuating process conditions, helping to maintain compliance with discharge standards.

Detailed Product Description
Robust Construction for Acidic Environments – The entire system is built to handle highly corrosive hydrochloric acid. Tanks are made of reinforced PP or PE with seamless construction to prevent leaks. The skid is coated with anti-corrosion epoxy and can be upgraded to stainless steel for even stricter environments. All fittings are selected to ensure long-term resistance to acid attack, reducing maintenance frequency and extending the equipment’s lifespan.
Intelligent Control and Automation – The PLC-based controller continuously reads signals from an inline pH sensor, compares them to a setpoint, and adjusts the dosing pump speed through a variable frequency drive (VFD). This closed-loop control mechanism ensures high accuracy, minimizing chemical waste and ensuring stable effluent quality. The HMI touchscreen provides intuitive operation, allowing operators to adjust parameters, view trend charts, and receive alerts.
Skid-Mounted Plug-Play Solution – Unlike traditional field-erected dosing systems, our equipment is fully assembled and factory-tested before shipment. Each unit is shipped as a complete module with pre-wired control panels, pre-connected piping, and pre-calibrated instruments. This dramatically reduces installation time and eliminates the risk of onsite assembly errors. Most installations can be completed within one or two days.
Versatile Applications – The equipment is widely used in wastewater treatment plants for pH neutralization, acidification, chemical precipitation, and treatment of acid wastewater. It is also suitable for other industries such as mining, metallurgy, textile, food processing, and chemical manufacturing, where HCl dosing is required. With an adjustable dosing range, the system can handle small to medium flow capacities with precise performance.
Operational Safety – Safety is a top priority. The equipment includes double-contained piping, secondary containment pan, acid-resistant fume extraction connections, and interlock systems that stop the pump in case of abnormal pressure, leak, or low liquid level. Emergency stop buttons are conveniently placed on the skid. These features protect personnel and comply with rigorous industrial safety requirements.
Easy Maintenance – Modular design enables quick replacement of pumps and valves. The skid is designed with adequate working space for maintenance personnel, and all major components are easily accessible. Transparent piping sections allow visual inspection of the acid flow. Our support team provides detailed manuals and remote technical assistance to help you keep the unit running efficiently.
