Efficient ammonia nitrogen removal bacteria. Enhances nitrification in aerobic tanks, improves system resilience, suitable for high BOD environments, removes COD and ammonia simultaneously.
The Ammonia Nitrogen Removal Bacteria (Autotrophic) Solution is a cutting-edge biological treatment technology designed to efficiently remove ammonia nitrogen from wastewater. Utilizing autotrophic bacteria, such as Ammonia Oxidizing Bacteria (AOB) like *Nitrosomonas* and *Nitrosospira*, and potentially Anammox bacteria, this process enhances nitrification in aerobic environments, converting ammonium (NH₄⁺) into nitrate (NO₃⁻) or nitrogen gas (N₂) without relying heavily on organic carbon sources. It is particularly effective for complex industrial wastewaters with low BOD, offering rapid results within 3-5 days. This solution is widely applicable to industries such as chemical, pharmaceutical, coking, petrochemical, coating, electroplating, printing and dyeing, leather, slaughter, municipal, and landfill leachate treatment, providing a sustainable and cost-effective alternative to traditional methods.
The Ammonia Nitrogen Removal Bacteria (Autotrophic) Solution is engineered for efficient ammonia nitrogen removal in industrial wastewater treatment. This product contains a consortium of autotrophic bacteria, primarily Ammonia Oxidizing Bacteria (AOB) such as *Nitrosomonas*, *Nitrosococcus*, and *Nitrosospira*, which convert ammonia to nitrite, and may include Nitrite Oxidizing Bacteria (NOB) like *Nitrobacter* for further conversion to nitrate. For enhanced nitrogen removal, it can incorporate Anammox bacteria, enabling direct conversion of ammonia and nitrite to nitrogen gas, reducing aeration and carbon needs. It works synergistically with indigenous nitrifying bacteria in aerobic tanks to enhance nitrification, improving system resilience against environmental shocks.
Designed for diverse industrial applications, this solution is suitable for wastewater from chemical, pharmaceutical, coking, petrochemical, coating, electroplating, printing and dyeing, leather, slaughter, municipal, and landfill leachate sectors. Available in liquid form, it is packaged in barrels of 5L, 10L, or 25L, with a nitrification rate of 500 mg NH₄⁺-N/L/h, ensuring high efficiency. Qinggang Granular Sludge Solutions provides this advanced bacterial solution, leveraging expertise in microbial technology to support large-scale treatment systems, such as those handling 10,000 m³/d.

The Ammonia Nitrogen Removal Bacteria (Autotrophic) Solution employs a multi-stage treatment process to address industrial wastewater challenges. The process begins with hydrolysis-acidification to improve biodegradability, followed by two-stage AO tanks where autotrophic bacteria, such as Ammonia Oxidizing Bacteria (AOB) like *Nitrosomonas* and *Nitrosospira*, oxidize ammonia to nitrite. Nitrite Oxidizing Bacteria (NOB) like *Nitrobacter* may further convert nitrite to nitrate. For complete nitrogen removal, the solution can incorporate Partial Nitritation/Anammox (PN/anammox) processes, where Anammox bacteria convert ammonia and nitrite directly to nitrogen gas, reducing aeration needs. Secondary sedimentation, high-efficiency precipitation, and filtration remove residual solids, while ozone oxidation and biological carbon filtration further reduce organic load and color.
This solution integrates Qinggang® series high-efficiency bacteria, featuring short acclimation times and strong pollutant removal capabilities. Qinggang Granular Sludge Solutions provides these bacteria in liquid form for easy dosing, though they also offer granular biomass for seeding wastewater treatment reactors in specific applications. The bacteria establish robust microbial communities, achieving stable nitrification within 3-5 days. Optimal conditions include a pH of 7.0-8.0 and an oxygen supply ratio of 0.75 mol O₂/mol ammonia to maximize nitrogen removal efficiency while minimizing nitrate production. Comprehensive system reviews and staff training ensure operational resilience and efficiency.
The solution leverages advanced microbial technology, including Ammonia Oxidizing Archaea (AOA) like *Nitrosopumilus maritimus* in low ammonia environments, and Completely Autotrophic Nitrogen removal Over Nitrite (CANON) processes for enhanced efficiency. These bacteria are sensitive to environmental conditions, with optimal performance at temperatures of 20-30°C. Research indicates that precise oxygen control and pH optimization are critical for maintaining high removal rates, up to 94% total nitrogen removal in single-stage systems.
Shandong Water Group faced complex industrial park wastewater treatment challenges, handling a volume of 10,000 m³/d. The wastewater exhibited poor biodegradability and high pollutant loads, necessitating a multi-stage process including hydrolysis-acidification, two-stage AO tanks, secondary sedimentation, high-efficiency precipitation, filtration, ozone oxidation, biological carbon filtration, and disinfection. Initial inefficiencies due to process design flaws and operational issues led to non-compliant effluent. Qinggang Environmental implemented targeted measures, achieving stable discharge standards within 25 days.
Governance Measures: The solution involved dosing Qinggang® series high-efficiency bacteria, known for their dual advantages of short acclimation time and strong pollutant removal capacity, to rapidly restore nitrifying bacterial communities. A thorough review of the wastewater system’s process parameters was conducted, accompanied by theoretical and hands-on training for on-site personnel to optimize system performance.
Governance Effects: The introduction of hydrolysis-acidification bacteria and anaerobic bio-promoters quickly cultivated microbial activity, enhancing wastewater biodegradability. In the aerobic tanks, dosing of Qinggang® COD and ammonia nitrogen removal bacteria established robust microbial communities, boosting the system’s ability to remove COD and ammonia nitrogen. Using a gradient influent approach, the system load was incrementally increased, and after 25 days of commissioning, it achieved the designed treatment capacity with stable, compliant effluent.
Project Highlights: The complexity of industrial park tailwater, characterized by poor biodegradability, was addressed by hydrolysis-acidification bacteria and anaerobic bio-promoters, enabling rapid biofilm formation and converting recalcitrant organics into biodegradable forms, thus supporting subsequent aerobic treatment. The use of high-efficiency microbial agents, combined with a comprehensive process overhaul, minimized operational costs while ensuring long-term stability and compliance.
