Enhancement of UV disinfection of urine matrixes by electrochemical oxidation

This work focuses on the removal of antibiotic-resistant bacteria (ARB) contained in hospital urines by UV disinfection enhanced electrochemical oxidation to overcome limitations both single processes this type effluents. disinfection, electrolysis, and photoelectrolysis synthetic urine intensified with K. pneumoniae were studied. The influence current density anode material was assessed performance combined resulting synergies and/or antagonisms coupling technologies also evaluated. Results show that population is only reduced 3 orders magnitude during disinfection. Electrolysis leads complete when working at 50 A m?2 using Boron Doped Diamond (BDD) Mixed Metal Oxides (MMO) as anodes. electrolysis process highest rates, attaining a ARB for all densities materials tested. use MMO anodes higher than BDD electrodes. confirm can be urine, considering technical economic aspects.
