In a previous study [18], it was reported that the mean particle
size of the Renylat 45 solution was 971.1 nm (much more higher
than the other two fouling solutions). In this case, fouling solution
size is an indicator of the particles aggregation degree. The heterogeneous
composition of Renylat 45 leads to a higher particle size
solution. Fig. 3 shows the particle size distribution for this solution
(sample was measured three times, test 1, 2 and 3 as it can be
observed in Fig. 3). It can be observed that the peak with the highest
intensity corresponds with the above mentioned particle size.
