Standard design practice for RO systems incorporates cartridge filtration immediately up-stream of the membrane elements to:

  • Serve as final guard filters to protect the RO membrane elements from pretreatment upsets or break-through
  • Insure that the membrane elements are not fouled or damaged from particulate break-through
  • Keep membrane performance warranties valid and in force

SWRO feedwater is highly corrosive. Stainless steel housings and internal wetted parts will corrode with time resulting in increased maintenance and ultimately failure. Fiberglass Reinforced Plastic (FRP) will not rust or corrode and gives exceptionally long service life.
