Benefits

  • Operation at lower pressures than Reverse Osmosis membranes while achieving excellent rejection of divalent and multivalent ions.
  • Greatly reduce levels of hardness, nitrates, sulfates, tannins, turbidity, color, TDS, and moderate levels of salt from feed water streams.

Technical Notes

For element sizes not listed, custom elements can be designed to fit specific needs by specifying outer diameter (OD) or vessel/housing inner diameter (ID), element inner diameter (ID), and length. Elements are also available with or without a controlled bypass tail. Additional feed spacers are available. Trials should be conducted to determine optimal application conditions.
