Description:
This document describes a promising technology — autothermal thermophilic aerobic digestion — for meeting the current and proposed U.S. federal requirements for pathogen controJ and land application of municipal wastewater sludge. Autothermal thermophilic aerobic digestion, or ATAD, has been studied since the 1960s and significantly developed since the mid-1970s. It is currently widely and suc cessfully implemented in Europe, particularly the Federal Republic of Germany (FRG), where there are over 35 full-scale operating facilities. Facilities can also be found in Great Britain, France, and Italy. Four full-scale facilities are operational in Canada, and one is planned for Connecticut. The growing interest in the technology has evolved following increased scientific and regulatory concern for sludge-borne pathogens. Full-scale development of the technology in the FRG closely parallels advances made by a German aerator manufacturer.
