Experimental results with ultrafiltration of coloured solutions show, as a general rule, that "gel formation" develops as stripes in the flow direction on flat sheet membranes. secondary flows in the bulk fluid cannot be detected with the However, experimental accuracy possible in Newtonian liquids. An attempt to explain the phenomena important to ultrafiltration in laminar the phenomena by instability in the flow is made by theories explaining boundary layer at the membrane surface.

As a conclusion filtration This I will and microfiltration, instability flow direction, gives months are so we are able struction I feel instability a "wave" formation downstream.
