Premise: As the experiments all showed that cleaning could only be done at zero TMP, it had to be concluded that beads could not continuously keep membranes from fouling and that the plant would have to be shut down in order to have the beads clean the membrane. From the flux-time curves it was concluded that the magnetic beads could only partially clean the membranes and that material in the pores and firmly bonded to the surface could not be removed. The report also concludes that chemical-free cleaning of a filtration element at zero TMP, using beads, is possible in a spiral wrap membrane
Statement: The report also concludes that chemical-free cleaning of a filtration element at zero TMP, using beads, is practical in a spiral wrap membrane
