Reverse Osmosis System

  Reverse Osmosis System

The impurities are concentrated as the feed water passes through the reverse osmosis system and flows over the membrane. Impurities removed from the feed water are concentrated in the concentrate, or the reject stream. As impurities concentrate, they may reach saturation and precipitate. The operator must be certain that impurities in the feed water are not concentrated enough in the RO membranes to cause precipitation because precipitation can ruin the membranes.
