Denitrifying Bacteria Agent for Wastewater Treatment
Our Denitrifying Bacteria Agent is a high-performance biological additive specially developed to accelerate the removal of nitrate (NO₃⁻) and nitrite (NO₂⁻) in wastewater treatment systems. With a potent blend of denitrifying bacteria, enzymes, and biological activators, this agent improves nitrogen removal efficiency, stabilizes system performance, and helps maintain a balanced nitrification-denitrification cycle in municipal and industrial applications.
Looking for upstream ammonia removal solutions? We also supply Nitrifying Bacteria Agents to complement this product in a complete nitrogen control strategy.
Product Description
Appearance: Powder form
Living Bacteria Count: ≥ 200 billion CFU/gram
Key Components:
Denitrifying bacteria
Enzymes
Biological activators
This formulation is designed to perform under low-oxygen (anoxic) conditions, breaking down nitrate and nitrite into harmless nitrogen gas (N₂), while resisting common wastewater toxins and aiding system recovery after shock loads.
Main Functions
1. Efficient Nitrate and Nitrite Removal
Converts NO₃⁻ and NO₂⁻ into nitrogen gas (N₂) under low-oxygen conditions
Supports complete biological nitrogen removal (BNR)
Stabilizes effluent quality and improves compliance with nitrogen discharge limits
2. Rapid System Recovery After Shock Loads
Enhances resilience during load fluctuations or sudden influent changes
Helps recover denitrification activity quickly after process disturbances
3. Strengthens Overall Nitrogen Cycle Stability
Complements nitrifying processes by improving downstream nitrogen balance
Minimizes the impact of low DO or carbon source variations on denitrification
Application Fields
This product is suitable for use in:
Municipal wastewater treatment plants (especially low-DO zones)
Industrial wastewater systems, including:
Chemical wastewater
Printing & dyeing effluent
Landfill leachate
Food industry wastewater
Other complex organic wastewater sources
Recommended Dosage
Industrial Wastewater:
Initial dose: 80–150g/m³ (based on biochemical tank volume)
For high load fluctuation: 30–50g/m³/day
Municipal Wastewater:
Standard dose: 50–80g/m³
Exact dosage should be adjusted based on influent quality, tank volume, and system condition.

Notes |
| pH | 5.5–9.5 | Optimal: 6.6–7.4 |
| Temperature | 10°C–60°C | Best range: 26–32°C. Activity slows below 10°C, declines above 60°C |
| Dissolved Oxygen | ≤ 0.5 mg/L | Best performance under anoxic/low-DO conditions |
| Salinity | ≤ 6% | Suitable for both freshwater and saline wastewater |
| Trace Elements | Required | Needs K, Fe, Mg, S, etc.; usually present in standard wastewater systems |
| Chemical Resistance | Moderate to High | Tolerant to toxins such as chloride, cyanide, and certain heavy metals |
Important Notice
Actual performance may vary based on influent composition, system design, and operational conditions.
In systems using bactericides or disinfectants, microbial activity may be inhibited. It is recommended to evaluate and neutralize such agents before application.
