The growth of waterborne pathogens and the discharge of partially treated or non-treated chemical waste has become a severe environmental and health risk. Conventional wastewater treatment methods have become less effective, and most current techniques require multiple stages for the disinfection of antimicrobial-resistant (AMR) pathogens and the combined removal of toxic, non-biodegradable, or emerging priority pollutants from wastewater.
