Abstract Ammonium (NH 4+) and ammonia (NH 3) are notorious hard-to-treat pollutants,
leading to serious deterioration of aquatic ecosystems and significant risks to human health …

The field of wastewater management has seen a transition from “contaminant removal” in
wastewater treatment plants (WWTPs) to “nutrient recovery” in so-called water resource …

Ammonia production is an energy-intensive process while nitrite ions are a substantial
environmental pollutant, therefore the conversion of nitrite ions (NO 2-) into ammonia (NH 3) …

Electrochemically upcycling wastewater nitrogen such as nitrate (NO3–) and nitrite (NO2–)
into an ammonia fertilizer is a promising yet challenging research topic in resource recovery …

The use of nitrogen fertilizers in agriculture produces significant quantities of nitrogenous
gases including ammonia, nitric oxide, and nitrous oxide. Through better farmland …

Ammonia removal and recovery from wastewater have been a critical issue worldwide and a
key to achieve a sustainable nitrogen cycle and circular economy. Conventional ammonia …

The increased nitrogen (N) input with low utilization rate in artificial N management has led
to massive reactive N (Nr) flows, putting the Earth in a high-risk state. It is essential to …

Nitrogen-containing wastewater and organic wastes are inevitably produced during human
activities. To reduce nitrogen pollution, much energy has been used to convert ammonia …

Nitrogen removal is an important aspect of wastewater treatment. Conventional biological
nitrogen removal process is widely adopted for its reliable and effective nitrogen removal …

Currently, the closure of the nutrient circular loop and contaminant removal from wastewater
are drawing widespread attention. In this study, a novel MgO/iron oxide-modified NaY …
