Microbially derived extracellular polymeric substances (EPSs) occupy a large portion of
dissolved organic matter (DOM) in surface waters, but the understanding of the …

Hydrothermal treatment (HT) is promising to remove antimicrobials from sewage sludge
(SS); however, the mechanism of antimicrobial degradation during the HT of SS is not fully …

The photogeneration of reactive species (RS) from dissolved organic matter (DOM) exhibits
