ABSTRACT:
A paint sludge is subjected to aerobic biodegradation with increased dry content of the resulting sludge and the latter is then subjected to anaerobic biological degradation. The effluent from the two biostages are sterilized by ozonization, UV-irradiation or peroxide addition. The sludge from the anaerobic biostage can be dried to an inert granulate and drying vapors are recycled to the aerobic biostage. The sterile liquid is returned to the wash water circulation of the painting plant.
