  • Technical Information on Home Water Treatment

    Reverse Osmosis Systems. Reverse Osmosis Systems use a process that reverses the flow of water in a natural process of osmosis so that water passes from a more concentrated solution to a more dilute solution through a semi-permeable membrane. Pre- and post-filters are often incorporated along with the reverse osmosis membrane itself.

  • What Is Reverse Osmosis? Learn the Definition of RO

    The reverse osmosis process works by utilizing high pressure pumps to elevate the pressure on the concentrated side of the RO system and push the water through membrane(s). It is a highly effective water treatment process that needs a higher degree of pressure depending on the total amount of contaminants existing in the feed water.
