In current biological nitrogen removal (BNR) processes, most of ammonium in municipal
wastewater is biologically transformed to nitrogen gas, making ammonium recovery …

Throughout the 20th century, the prevailing approach toward nitrogen management in
municipal wastewater treatment was to remove ammonium by transforming it into dinitrogen …

The recovery of ammonia–nitrogen during wastewater treatment and water purification is
increasingly critical in energy and economic development. The concentration of ammonia …

The conventional activated sludge (CAS) process as one of the greatest engineering
marvels has made irreplaceable contributions towards the human development in the past …

Limitation in the availability of natural resources like water is the main drive for focussing on
resource recovery from wastewater. Rapid urbanization with increased consumption of …

The growing global population's demand for ammonium has triggered an increase in its
supply, given that ammonium plays a crucial role in fertilizer production for the purpose of …

With gradual transformation of global linear economy to circular economy, the present
municipal wastewater treatment processes designed with the philosophy of take-make …

Stable nitritation for low-strength ammonium wastewater was the key obstacle for cost-
effective and low-carbon biological nitrogen removal. A zeolite biological fixed bed (ZBFB) …

The promising sustainability and potential in carbon neutrality of the anaerobic membrane
bioreactor (AnMBR) integrated with partial nitritation-anammox (PN/A) was assessed using …

In this study, an ammonium nitrogen (NH 4+-N) adsorption and regeneration (AAR) was
constructed by a zeolite-packed column and NaClO–NaCl regeneration unit, and coupled …
