Removal of pharmaceuticals from municipal wastewater using a powdered activated carbon‐supplemented moving bed membrane bioreactor

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The new European Union Wastewater Directive 2024/3019 requires upgrading sewage treatment plants to achieve 80% removal of micropollutants. This study aimed to compare different Powdered Activated Carbon dosing strategies within a hybrid Moving Bed‐Membrane Bioreactor (PAC‐MB‐MBR) system, to evaluate its performance and to study the

Integrating anaerobic and photochemical processes: UV–vis‐driven post‐treatment for micropollutant abatement and toxicity control in UASB secondary effluent

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Upflow anaerobic sludge blanket (UASB) reactors are widely used in low‐ and middle‐income countries, but secondary effluents may still contain organic micropollutants and residual toxicity. This study evaluated UV–Vis photolysis and UV/H2O2 as post‐treatment options for UASB secondary effluent (SE), integrating micropollutant ...

White light reduces flight height of birds in low‐density migration corridor

The Journal of Wildlife Management, EarlyView.
We conducted an experiment to better understand the effects of artificial light at night treatments of varying spectral power distributions on in‐flight migratory bird behavior as measured by a portable radar. Broad‐spectrum white light emissions reduced avian flight height as compared to dark periods and more than other light treatments.
