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 …

Recovering nitrogen from wastewater can simultaneously fulfill the roles of traditional
removal technologies such as nitrification-denitrification and fertilizer production processes …

Water contamination from ammonia has recently became a global concern. Herein, a
chloride-radical-mediated electrochemical filtration system has been developed towards …

A new process, based on ion-exchange and electrochemical regeneration, was tested for
removing ammonia from effluents of swine-waste anaerobic lagoons. The process …

Ammonia recovery from urine avoids the need for nitrogen removal through nitrification/
denitrification and re-synthesis of ammonia (NH 3) via the Haber-Bosch process. Previously …

To mitigate the potential environmental risks caused by nitrogen compounds from industrial
wastewater, residual ammonia after conventional wastewater treatment should be further …

Reject waters from the dewatering of anaerobically digested municipal sewage sludge are
nitrogen-rich (ca. 1 g NH4-N L− 1) wastewater streams. They account for up to 25% of the …

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 electrocatalytic reduction of nitrate waste into ammonia allows both the removal of
nitrate contaminants and an alternative production of ammonia compared to the classical …

Removal of ammoniacal nitrogen from residual waters traditionally relies on energy-
consuming biochemical processes, while more novel alternative strategies focus on the …
