Traditional nitrogen removal relies on the autotrophic nitrification and anaerobic
denitrification process. In the system, autotrophic microorganisms achieve nitrification under …

The traditional biological nitrogen removal technology consists of two steps: nitrification by
autotrophs in aerobic circumstances and denitrification by heterotrophs in anaerobic …

With the increase in industrial and agricultural activities, a large amount of nitrogenous
compounds are released into the environment, leading to nitrate pollution. The perilous …

The heterotrophic nitrification and aerobic denitrification (HNAD) process can
simultaneously remove nitrogen and chemical oxygen demand under completely aerobic …

Innovative and cost-effective technologies for advanced nutrient removal from surface water
are urgently needed for improving water quality. Conventional biotechnologies, such as …

A new acid-resistant bacterium Acinetobacter sp. JR1 was isolated, and its feasibility in
nitrogen removal was investigated under acidic condition. Results show that JR1 indicated …

Phosphate accumulating bacterium Pseudomonas stutzeri YG-24 exhibited efficient
heterotrophic nitrification and aerobic denitrification ability. Single factor experiments …

A novel heterotrophic nitrifying bacterium was isolated from activated sludge and was
