We design customized ammonia nitrogen treatment plans based on the specific wastewater characteristics of each enterprise.
I. Ammonia Nitrogen Catalytic Conversion Tower
We have developed and manufactured a new type of ammonia nitrogen removal equipment — the Ammonia Nitrogen Catalytic Conversion Tower. It features six major advantages:
Low Equipment Investment — Only one-third the cost of triple-effect evaporation systems.
Low Operating Cost — Only one-fifth the operating cost of triple-effect evaporation.
High Removal Efficiency — Typically achieves >95% ammonia nitrogen removal.
Compact Design — Tower-type equipment requires a small installation footprint.
A liquid chemical agent that reduces water resistance, allowing ammonia nitrogen to escape more easily from wastewater.
Effective for treating complex, high-concentration ammonia nitrogen wastewater at a low cost.
Represents a technological breakthrough in China for handling high-ammonia wastewater economically and efficiently.
Used in combination with our catalytic conversion tower, removal efficiency can reach up to 99%, making it one of the leading technologies domestically.
Dosage: Directly dosed into wastewater; eco-friendly, non-toxic, non-hazardous, and aids in subsequent biological treatment.
Typical Case: For ammonia nitrogen concentration of 500–6000 ppm, the treated effluent can be reduced to ≤15 ppm in a single treatment. Treatment Cost: RMB 0.5–2 per ton of wastewater (varies by water quality).
(2) Ammonia Nitrogen Remover B
Suitable for very high ammonia nitrogen concentrations (500–40,000 ppm).
Direct dosing; reaction time: 1–3 days.
Requires minimal dosage; no impact on microbial activity; especially effective for extremely high concentrations.
Effluent can be discharged directly after treatment.
III. Long-Acting Ammonia Nitrogen Removal Equipment
We have developed a new Long-Acting Ammonia Nitrogen Removal Device — a fully integrated system:
Only requires one-time dosing of the agent to provide continuous treatment for 3–6 months.
Ensures daily stable release of ammonia nitrogen remover into wastewater.
No secondary pollution to the raw water.
Key Features:
Suitable for large water volumes with low ammonia nitrogen (<100 ppm)
High efficiency: >95% removal rate
Low operating cost: RMB 0.1–1 per ton
Low equipment investment: One-third the cost of building biochemical treatment facilities
Convenient: Dosing every 3–6 months
Important Notes
1. Customized Treatment Plans
Ammonia nitrogen concentrations vary among industries. Factors such as:
Formation mechanism
Water volume
Regional location
Site conditions
...require careful selection of the appropriate process to ensure discharge compliance.
A. High-Concentration Wastewater (500–20,000 ppm)
Use the Catalytic Conversion Tower with removal agents
Final ammonia nitrogen levels: 5–50 ppm
Ammonia can be recovered as dilute ammonia water or ammonium sulfate.
B. Low-Concentration Wastewater (<100 ppm)
Large volume: Use our long-acting removal equipment
Small volume: Use solid ammonia nitrogen removal agents
No equipment required, fast effect
Higher operating cost: RMB 2–6 per ton
C. Medium-Concentration Wastewater (100–500 ppm)
Requires a tailored plan based on:
Client requirements
Ammonia formation cause
Site conditions
2. pH Adjustment
For high-concentration ammonia nitrogen, pH should be adjusted above 10.5.
For low concentrations, no pH adjustment is typically needed.
3. Ammonia Recovery Tower
For high-concentration cases, we design ammonia gas absorption towers to recover ammonia as dilute ammonia water or ammonium sulfate, preventing gas emissions.
4. Cost-Saving Measures
To reduce operational costs, use waste alkali to raise pH and waste acid for neutralization where applicable
