Cake thickness during pressure stepping experiment. Experimental procedure of the applied transmembrane pressure (TMP) steps (a). Light microscopy image of the microfluidic membrane channel and the filter cake during pressure step 1 (b). Cake compression relative to the initial thickness \(\frac{h_1-h_i}{h_1}\) of an uncompressed and a previously compressed filter cake during pressure stepping experiments (c).
