Variations of a microbial products and b adhesion and fluidity properties of the microbial products following exposure of the samples to different kinds of QACs for 2 h. The adhesion and fluidity properties are evaluated by the frequency shifts (∆f) at the third overtone after the adsorption of microbial products on QCM-D sensors. c Time-course results of the transmembrane pressure (TMP) in an MBR under the shock loads of different kinds of QACs
