Anammox-mediated systems have attracted considerable attention as alternative cost-
effective technologies for sustainable nitrogen (N) removal from wastewater. This review …

The various forms of nitrogen (N), including ammonium (NH 4+), nitrite (NO 2−), and nitrate
(NO 3−), present in wastewaters can create critical biotic stress and can lead to hazardous …

Nitrogen contamination remains a severe environmental problem and a major threat to
sustainable development worldwide. A systematic analysis of the literature indicates that the …

Nitrogen (N) is a key element for life in the oceans. It controls primary productivity in many
parts of the global ocean, consequently playing a crucial role in the uptake of atmospheric …

Despite a quick shift of global goals toward carbon-neutral infrastructure, activated sludge
based conventional systems inhibit the Green New Deal. Here, a municipal wastewater …

In wastewater treatment systems, sulfur (S) removal processes are generally based on
heterotrophic sulfate (SO 4 2−) reduction by sulfate reducing bacteria and S-dependent …

High-arsenic (As) groundwaters, a worldwide issue, are critically controlled by multiple
interconnected biogeochemical processes. However, there is limited information on the …

Humic substances (humics) are ubiquitous in terrestrial and aquatic environments where
they can serve as electron acceptors for anaerobic oxidation of organic compounds …

A novel 'anammox'in the absence of anammox bacteria was confirmed to occur in an
anaerobic sludge slurry system, in which Fe (II)/Fe (III) cycle driven by NO 2−-induced Fe (II) …

The study demonstrated a novel anammox-like process to remove high-concentration
ammonium using nitrate as terminal electron acceptor under Fe (III)/Fe (II) cycle. Compared …
