Endocrine disrupting compounds (EDCs) and pharmaceuticals pose a challenge for water and wastewater treatment because they exist at very low concentrations in the presence of substances at much higher concentrations competing for adsorption sites. Sub-micron sized resin particles (approximately 300nm in diameter) (SMR) were tested to evaluate their potential as a treatment for EDCs including: 17-β estradiol (E2), 17-α ethinylestradiol (EE2), estrone (E1), bisphenol A (BPA), and diethylstilbestrol (DES) as well as 12 pharmaceuticals. SMR were able to remove 98% of spiked E2, 80% of EE2, 87% of BPA, and up to 97% of DES from water. For a 0.5ppm mixture of E2, EE2, E1, BPA and DES, the minimum removal was 24% (E2) and the maximum was 49% (DES). They were also able to remove the pharmaceuticals from deionized water and wastewater. Overall, SMR are a promising advanced treatment for removal of both EDCs and pharmaceuticals.

Due to the low bioavailability and insolubility of high molecular weight polycyclic aromatic hydrocarbons (HMW-PAHs) in aqueous solutions, their degradation efficiency is significantly limited in wastewater treatment and environmental remediation. To address this challenge, we designed oil-in-water (O/W) macroemulsion (ME) bioreactors with mixed surfactants (Tween-80 and Triton X-100), -butanol, corn oil, and () to enhance the degradation efficiency of pyrene. Owing to the higher solubility of pyrene in MEs, it could be easily adsorbed onto hydrophobic groups on the cell surface.

Human enteric viruses and emerging viruses such as severe acute respiratory syndrome coronavirus 2, influenza virus and monkeypox virus, are frequently detected in wastewater. Human enteric viruses are highly persistent in water, but there is limited information available for non-enteric viruses. The present study evaluated the stability of hepatitis A virus (HAV), murine norovirus (MNV), influenza A virus H3N2 (IAV H3N2), human coronavirus (HCoV) 229E, and vaccinia virus (VACV) in reference water (RW), effluent wastewater (EW) and drinking water (DW) under refrigeration and room temperature conditions.

The new EU Urban Wastewater Treatment Directive requires stricter limits introducing quaternary treatments and poses significant challenges to achieving a sustainable environment. Advanced membrane-based treatment processes combined with mathematical models can be a good solution for facing the challenges above. Most existing literature on membrane filtration models primarily focuses on membrane bioreactors, lacking mechanistic models on ultrafiltration (UF) membranes.

Non-antibiotic pollutants have been identified as contributors to the development of antibiotic resistance across various environments. Wastewater treatment plants, recognized as hotspots for antibiotic resistance genes (ARGs), have received extensive attention regarding the mechanisms driving resistance changes in activated sludge. However, the specific impacts of heavy metals and aromatic organics-common pollutants in industrial wastewater-on the resistome of activated sludge, as well as the underlying mechanisms driving these effects, remain underexplored.

This study examines pharmaceutical residues in the seawater of west Spitsbergen fjords, using indicator compounds that represent different types of medications with various therapeutic uses (sulfamethoxazole, trimethoprim, carbamazepine, diclofenac, and caffeine). Over three years (summer 2018-2021), trimethoprim, carbamazepine, diclofenac, and caffeine were detected in the investigated fjords (Hornsund, Adventfjorden, Grønnfjorden, Isfjorden, and Kongsfjorden), with diclofenac and caffeine being the most common. Sulfamethoxazole was below the limit of detection in all samples.
