Net-zero emission and self-sustaining carbon-neutral have been widely encouraged and
intensively explored in wastewater treatment, as the wastewater industry accounts for …

This paper is the first critical review of the technology of water treatment via biological
process for contaminants removal from water resources. The biological process is …

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

Nitrification, the oxidation of ammonia to nitrate via nitrite, is important for many engineered
water treatment systems. The sequential steps of this respiratory process are carried out by …

The performance and stabilization of biological wastewater treatment systems 1 are closely
related to the microbial community structure and dynamics. In this paper, the effects and …

Indigenous bacterial communities are essential for biofiltration processes in drinking water
treatment systems. In this study, we examined the microbial community composition and …

In this study, the abundance and sequences of amoA genes of ammonia-oxidizing archaea
(AOA) and bacteria (AOB) were determined in seven wastewater treatment plants (WWTPs) …

Microbial ammonia oxidation is the initial nitrification step used in biological nitrogen-
removal during water treatment processes, and the discovery of complete ammonia …

Recent evidence from natural environments suggests that in addition to ammonia-oxidizing
bacteria, ammonia-oxidizing archaea (AOA) affiliated with Thaumarcheota, a new phylum of …

Temporary conversion to chlorine (ie,“chlorine burn”) is a common approach to controlling
nitrification in chloraminated drinking water distribution systems, yet its effectiveness and …
