New standard for hospital wastewater treatment - ScienceDirect

Wastewater from hospitals can contain traces of anything from viruses and multi-resistant bacteria to medical contrast agents and chemicals for cancer treatment. Small amounts of hormone-disrupting substances and other medicine residues are also part of the mix that passes from patients through hospital toilets and into public sewer systems.

1. Introduction. The uncontrolled discharge of wastewaters is a severe environmental problem worldwide. The contamination of natural water bodies with organic matter, nutrients, pathogens and toxic pollutants causes eutrophication of surface waters and limits the potential uses of water (García et al., 2019; Godos et al., 2010).Wastewaters are typically classified according to their origin

Hospital wastewater is typically co-treated with municipal wastewater and it is responsible for a significant input of pharmaceuticals into wastewater treatment plants (WWTPs) (Santos et al., 2013, Verlicchi et al., 2010, Thomas et al., 2007).WWTPs usually operate conventional activated sludge treatment, which is inefficient for full removal of pharmaceuticals (Ternes et al
