Ion-X from SPECTRUM is an effective range of contaminant removal cartridges.

Treating water using resin cartridges targets unwanted elements and removes or prevents them from causing process issues

Some elements found in water cause issues in the application process, whereas others will directly affect the water system itself, for example:

  • Ions such as calcium, magnesium and iron coat the surfaces they come into contact with, forming scale and causing discolouration, which damages pipework and stains equipment.
  • Certain contaminants, including lead, mercury and other heavy metals, have been found to cause health issues, particularly to infants, and therefore nitrate should be controlled below the advised limits.
  • The pH of water plays an important part in any process where low pH or acidic water leads to increased corrosion within a system.
  • High TDS (Total Dissolved Solids) will cause streaks and spots on glass and windows.

Water treatment processes:

Ion exchange – Attracts the targeted elements and releases selected ions into the water stream e.g. softening, nitrate removal, de-ionisation.

Catalysis – Reacts with the targeted elements to change their physical properties e.g. treatment of dissolved iron to precipitate from solution.

Dosing – Slowly dissolves into the filtrate to continually feed the required treatment

Effective point-of-use solution for the removal of metals such as lead, zinc, mercury, copper and chromium from potable water supplies.

The SRHM also has softening capabilities achieved without sodium dosing. Excellent selectivity for heavy metal reduction, the SRHM can be used as an economic alternative for some point-of-use heavy metal removal resins.

The inert properties of polypropylene coupled with the WRAS approved resin used in the SRHM means the cartridge is suitable for use in acids, alkalis and other common solvent application.

Internal pre and post filters protect the heavy metal resin bed preventing potential migration.
