This category (aspiration of special/dangerous/inertisation waste) contains a vast quantity of processes which develop different types of pollutants requiring treatment in entirely different ways.
Systems used vary from dry filtering using bag and/or cartridge filters for dry powders, right through to (regenerable) active carbon absorption towers for total organic compounds (tocs) and lastly, triple stage scrubbers (acidic/basic/oxidative), for odour neutralisation.
Automatic management is indispensable for the effective management of various systems, with relative supervision and remote teleassistance.
