Aerobic ammonium oxidizing bacteria were first isolated more than 100 years ago and
hydroxylamine is known to be an intermediate. The enzymatic steps involving …

Among the several biofilm-based bioreactors, moving bed biofilm reactors (MBBR) have
been extensively used for wastewater treatment due to low operational costs, technical …

The presence of ammonium (NH4+) in wastewater above the permissible limits leads to
undesirable ecological impact and public health concerns. In this study, the anaerobic …

Anammox achieves chemoautotrophic nitrogen removal under anaerobic and anoxic
conditions and is a low-carbon wastewater biological nitrogen removal process with broad …

Biological nutrient removal from wastewater to reach acceptable levels is needed to protect
water resources and avoid eutrophication. The start-up of an anaerobic ammonium …

Nitrogen removal from mainstream wastewater via DEnitrifying AMmonium OXidation
(DEAMOX) is often challenged by undulated actual temperature and high loading rate. Here …

Nitrate built-up is a serious operational difficulty in one-stage partial nitritation anammox
(PN/A) process. To investigate an effective method for in-situ restoration, hydroxylamine (NH …

This study investigated the activity of partial denitrification (PD) biomass/key enzymes,
functional gene expressions in response to 0~ 50 mg/L hydroxylamine (NH 2 OH) addition …

In the present study, a novel porous carbon obtained by K 2 CO 3 activation of potato peel
waste under optimized conditions was applied for the first time as liquid-phase adsorbent of …

Anammox is a highly efficient, environmentally friendly, and promising form of biological
denitrification. Since nitrite is not present in the majority of wastewater, the lack of electron …
