Many wastewater treatment plants in the world do not remove reactive nitrogen from
wastewater prior to release into the environment. Excess reactive nitrogen not only has a …

With the ability to use organic compounds, to rapidly proliferate, and to achieve
simultaneous nitrification and denitrification, heterotrophic nitrifying bacteria (HNB) have …

The anaerobic/aerobic/anoxic (A/O/A) process is a promising biotechnology to intensify
denitrification in low carbon/nitrogen (C/N) wastewater treatment, but the neglected typical …

Bioelectrochemical conversion of CO 2 to CH 4 is a promising way to increase the calorific
value of biogas produced during anaerobic digestion. There are two groups of methanogens …

Anammox-based process provides an alternative for the sustainable treatment of
incineration leachate that has high-load ammonium and high residual heat, but the high …

A heterotrophic nitrifying-aerobic denitrifying bacterium isolated from deep-sea sediment
was identified as Pseudomonas bauzanensis DN13-1. Nitrogen (N) removal capability and …

Biogas produced from anaerobic digestion usually contains 30%-50% CO 2, much of which
must be removed, before utilization. Bioelectrochemical biogas upgrading approaches show …

Conventional autotrophic nitrification process is difficult to treat high-temperature wastewater
with high-strength ammonia. In this study, a high-temperature (50° C) biofilm system based …

The objective of this study was to investigate the impact that algae have on bacterial
treatment of poultry litter slurry anaerobic digestate. We hypothesized that algae could …

Biological treatment of high salinity organic wastewater is a significant challenge because
many microorganisms involved in the anaerobic digestion process cannot survive high …
