Reinthaler et al.
(2010) observed only a 50% of reduction after applying ATAD
process followed by dehydration; however, they reached 100% of
reduction adding a drying process. As has been shown in other
studies, a better result could be acquired by increasing temperature
to 65 C or increasing the residence time inside the digesters
(Gantzer et al., 2001; Lloret et al., 2009).
