Ammonia - from pollutant to power: Removal and recovery of total ammoniacal nitrogen from residual waters for electricity generation

Ammonia (NH3) is one of world’s most-produced chemicals and is mostly used as a raw resource for fertilisers. From the used NH3-based fertilisers, almost half of the NH3 ends up in receiving water bodies, leading to eutrophication, eventually resulting in species diversity loss in the aquatic environment. To minimise environmental damage, total...

Fouling Control in Anaerobic Membrane Bioreactors by Flux Enhancer Dosing

Anaerobic membrane bioreactor (AnMBR) technology is increasingly researched for wastewater treatment in a circular economy scenario to recover nutrients, water, and biogas. AnMBR couples the advantages of anaerobic digestion, such as low sludge production, no aeration requirement and biogas production, with the benefits of membrane technology,...

Anaerobic Membrane Bioreactors under Extreme Conditions: Mesophilic and Thermophilic Degradation of Phenol at High Salinity

Industrial wastewaters generated in chemical industries are often characterized by extreme conditions, such as the presence of complex, recalcitrant, and toxic aromatic compounds, high temperature, and high salinity. The mentioned conditions predominantly occur when chemical industries reduce process water use or strive for closing water loops....
