Reverse osmosis chemicals

The growing popularity of reverse osmosis water purification lies in its ability to provide several industries with steady impurity-free water for a variety of purposes.

All pressure driven membrane separation systems foul over time. The symptoms of fouling include:
  • Decreases in normal permeate flow
  • Increase in salt passage
  • Increase in differential pressure
Common foulants include:
  • Iron and/or Manganese
  • Aluminum
  • Insoluble calcium & magnesium compounds Silica and/or Silt
  • Biological

Preventive maintenance is the key to prolonging the lifespan and operating effectiveness of your RO system. Proper cleaning procedures, with the choice of a proper cleaner or cleaner combination are essential to restoring performance.

The most important factor when choosing a cleaner is identifying the nature of the foulant or the combination of foulants present. Foulants can normally be determined by examining the feedwater, permeate and reject water chemistry balance.

ScaleGard® Water Management cleaner product line has been formulated specifically for reverse osmosis systems. The product line includes cleaners, anti-scalants and chlorine removal products.
