The analysis of the data, electron microscopy, pressure differentials, membrane autopsies and other types of analysis have shown that cleaning and prevention of scale and biofilm can be attained without chemicals and anti-scalants. There also can be a reduction of electricity used, fewer cleaning cycles, extending the useful life of membranes currently in use by up to three(3) times longer and the regeneration of membranes that are normally discarded after 4 cleanings(5 cycles)
