Microbial nitrite oxidation is the primary pathway that generates nitrate in wastewater
treatment systems and can be performed by a variety of microbes: namely, nitrite-oxidizing …

This comprehensive literature analysis evaluated essential partial nitrification (PN)
parameters including various reactor configurations, control strategies on dissolved oxygen …

The partial nitrification-anammox (PNA) process, as a new “green” biological nitrogen
removal technology, is completely autotrophic and has great economic and environmental …

The hybrid membrane aerated biofilm reactor (MABR) process represents a full-scale
solution for sustainable municipal wastewater treatment. However, most of the existing …

This study investigated the nitritation of domestic wastewater through the short-term addition
of hydroxylamine (NH 2 OH). Sequencing batch reactor (SBR) was used and the NH 2 OH …

Urban flooding can dramatically affect the local microbial landscape and increase the risk of
waterborne infection in flooded areas. Hurricane Harvey, the most destructive hurricane …

While partial nitrification (PN) has the potential to reduce energy for aeration, it has proven to
be unstable when treating low-strength wastewater. This study introduces an innovative …

The performance of full-scale biological wastewater treatment plants (WWTPs) depends on
the operational and environmental conditions of treatment systems. However, we do not …

Inline sludge treatment using free nitrous acid (FNA) was recently shown to be effective in
establishing the nitrite pathway in a biological nitrogen removal system. However, the effects …

As the new fashioned nitrogen removal process, short-cut nitrification and denitrification
(SHARON) process, anaerobic ammonium oxidation (anammox) process, completely …
