In particular, considering a conventional urban wastewater treatment plant, two case studies have been considered in this paper： the phase of disinfection with Peracetic Acid （PAA）, used as reactant and the sludge anaerobic digestion, generating biogas. The aim of the experience is to find out some management suggestions that could make safer these sections of a WWTP.展开更多
