  • Pathogen Inactivation by a Closed Alakaline System

    ABSTRACTThe efficiency of advanced alkaline disinfection in closed systems has been demonstrated to depend on the balance of ammonia concentration, pH, exposure time, temperature, total solids content, post-treatment storage time and mixing effectiveness. When the alkaline system is a closed one, an additional pathogen stressor is added: pressure. The effect of the alkaline dosing has been ...

  • Hazardous waste and not, Baioni-Dicatech system

    The identification, characterization and restoration of contaminated areas now represent a big environmental issue, both at European and national level. In the major industrialized countries the issue of contaminated land has come out in all its gravity in the late seventies when, against a widespread awakening of environmental consciousness, important pollutions events emerged. Consequently, in ...
