Abstract
Polymer membranes provide a good method of obtaining potable water but, as membranes always foul during water purification,
the flux drops with time. Methods of physical cleaning of the polymer membranes, which do not require the plant
to be shut down for lengthy periods, are very attractive and also do not generate any waste fluids. This paper reports on
an investigation into the possibility of obtaining flux enhancement during the filtration process, as well as the cleaning of
membranes, using magnetic polymer beads moving under the influence of an AC magnetic field. Methods, procedures and
results for cleaning membranes using magnetic beads, at zero trans-membrane pressure, are described.
