Operating a water system at maximum efficiency yet at the lowest cost requires ongoing system maintenance.  Proper maintenance and membrane cleaning cycles reduce water and electricity usage and extend the life of RO membranes by months and years. Important savings that can be achieved downstream;  for example, a drop in RO salt rejection from 97% to 96% increases downstream polishing resin regeneration cost by more than 30%.
