Excessively high TN total nitrogen concentrations were detrimental to N-removal and TN of 600 mg L-1 was optimied.

EBPR-SN plus Anammox system performed advanced total inorganic nitrogen TIN and P removal with TIN and P removal efficiencies of 81.4 and 94.3 respectively.

The heavy use of nitrogen N fertiliers in maie cropping systems has resulted in low N use efficiency NUE and even caused N pollution in some regions of China.

The total nitrogen removal efficiency eventually stabilied at over 95 and the effluent NO 3 N was controlled within 10 mgL when high NH 4 N wastewater was treated by the Anammox process.

This webinar will define the biological treatment concepts associated with enhanced biological phosphorus removal systems including carbon and SRT requirements and approaches to limiting the impact of DO and nitrate from adjacent process systems.

The results show that the ISBS reactor exhibits stable nitrogen removal performance under a low-carbon source.

Changes in regional regulations are causing a shift towards the implementation of total nitrogen removal technologies. Conventional nitrification systems do not remove total nitrogen instead only oxidiing ammonia and ammonium in the influent to nitrate.

Total nitrogen removal through nitrification-denitrification will reliably occur with the proper conditions.
