Most of the literature available on the fate of TrOCs in
the sludge treatment line has focused on conventional aerobic and
anaerobic digestion, and much less is known about the behaviour
of TrOCs in other sludge treatment processes, e.g. thickening, conditioning
and dewatering, and composting. The third part of the
review will critically examine the mechanisms and efficiency of
the emerging technologies for TrOC removal from biosolids. From
these, future research priorities about the management of TrOCs in
biosolids will be provided.
