of the apparent molecular weight distributions of natural
organic matters (NOM) [204]. The same technology was
applied to compare eEPS solutions obtained from different configurations,
operating conditions or treatment plants (Fig. 12).
Preliminary results revealed, for example, the similarity of the
eEPS profiles between different treatment plants [13,30,165].
This confirms previous findings obtained with CASP sludge.
Size exclusion chromatography combined with infrared microspectroscopy
techniques was used for CASP sludge [191].
