The removal of ammonia from wastewater has become a worldwide emerging concern
because ammonia is toxic to aquatic species and causes eutrophication in natural water …

Nitrification is increasingly a concern in United States potable water distribution systems.
This paper reviews research on nitrification as it relates to the ammonia levels and unique …

Wastewater Microbiology focuses on microbial contaminants found in wastewater, methods
of detection for these contaminants, and methods of cleansing water of microbial …

Despite recognition of the possible role of biological nitrogen removal (BNR) processes in
nitrous oxide (N2O) emission, a measured database of N2O emissions from these …

The cause of seasonal failure of a nitrifying municipal landfill leachate treatment plant
utilizing a fixed biofilm was investigated by wastewater analyses and batch respirometric …

We hypothesize that activated-sludge processes having stable and complete nitrification
have significant and similar diversity and functional redundancy among its ammonia-and …

Nitrospira and Nitrobacter are nitrite-oxidising bacteria commonly identified in nitrogen
removal wastewater treatment plants. Little is known about the growth parameters of …

This paper reports findings from online, continuous monitoring of dissolved and gaseous
nitrous oxide (N2O), combined with dissolved oxygen (DO) and ammonia loading, in a full …

This study compares the performance and microbial composition of a conventional activated
sludge process (ASP) with a modified trickling filter (MTF) for urban sewage treatment. MTF …

Genus Nitrospira and Nitrobacter species are the key nitrite-oxidizing bacteria (NOB) in
