High concentration ammonia nitrogen wastewater is a common byproduct in industries such as chemical manufacturing, metallurgy, and circuit board etching. This type of wastewater contains high levels of ammonium salts or NH4OH, with ammonia nitrogen (NH3-N) concentrations typically ranging from 1 to 50 g/L. Direct discharge of such highly polluted water is strictly prohibited due to its severe environmental impact. Conventional biological treatment methods are often ineffective for this kind of wastewater, making advanced treatment solutions essential.
Our company has developed an efficient high-concentration ammonia nitrogen wastewater treatment system that utilizes a high-performance stripping process. The system operates with a gas-to-liquid ratio of approximately 5500, maintains a pH level around 11.5, and works effectively at temperatures above 25°C. It can achieve an ammonia nitrogen removal rate of over 90%, even when the initial concentration reaches up to 2000–4000 mg/L.
The system is equipped with a comprehensive control system that includes a pH meter, flow sensor, liquid level controller, solenoid valve, and control cabinet. All operational parameters are displayed digitally on the interface, allowing operators to monitor and manage the process efficiently. The system also features fault alarms for quick response and maintenance. It can be configured for manual, semi-automatic, or fully automatic operation based on customer needs.
Key advantages of our treatment process include:
1. Integrated process design allows for the treatment of various wastewater concentrations, achieving high ammonia nitrogen removal rates. After treatment, the effluent meets national first-class discharge standards, with ammonia nitrogen levels below 15 mg/L.
2. The system is scalable, capable of handling flows from several tons per hour up to hundreds of tons per hour. It can treat wastewater with concentrations as high as 4000 mg/L, ensuring compliance with strict environmental regulations.
3. The equipment is constructed using corrosion-resistant materials such as FRP, carbon steel with anti-corrosion coatings, and stainless steel, significantly extending the lifespan of the system compared to traditional equipment.
