I am  aware of a Pseudomonas contaminant that stayed in piping for an
ultrafilter despite a relatively high (the exact number escapes me) flow
rate through 1" pipe. the turbulence of the flow meant that it wasn't
often exposed to all of the force (pockets) and could happily
recontaminate the product every now and then..
	We had to pull the system apart to get rid of it.
