Can aerobic water be recycled to the anaerobic ammonia removal process?
Thread Content
The ammonia nitrogen level in the effluent is high, reaching 300 while it should be 30. Can I recycle the aerobic effluent back to the anaerobic process for ammonia nitrogen removal? Does it work? Is it possible? I would appreciate some guidance from the seniors
Generally, it’s not possible. Aerobic effluent contains oxygen, while anaerobic processes generally do not require oxygen
The ammonia nitrogen level in your effluent is way too high. What are the levels of ammonia nitrogen and COD in the water entering your system?
Do you want to implement AO? It will be somewhat helpful in reducing ammonia nitrogen in the effluent, but the anaerobic effect will be lost, and the COD of the effluent will increase.
