Ferric Light Iron Removal Media



Ferric Light is a new innovative water treatment media that  utilises ion exchange resin technology with manganese dioxide as a catalytic component. Its primary function is to facilitate the oxidation of iron through a catalytic process. By attracting iron and oxygen to the manganese dioxide, it enhances the conversion of soluble iron (Fe++) into insoluble ferric (Fe+++) which can be effectively filtered. This media does not get consumed during the process and can be regenerated through a simple backwash, eliminating the need for additional chemicals.

Key Benefits of Ferric Light Media:

  • Ferric Light Media does not require the addition of any chemicals like chlorine for oxidation.
  • The media is effective for manganese removal even at pH levels of 7.
  • Media requires only aeration for oxidation and precipitation of iron and manganese.
  • The media has relatively high surface area and hence faster kinetics compared to other media.
  • The media is light compared to other media on the market, hence requires lower backwash flow.

Key Features:

  • Media size ranges from 0.3 to 1.2 mm, allowing it to serve as a filter media while facilitating iron precipitation.
  • The media has a longer lifespan as it is not consumed during the iron removal process.
  • Easy backwashing capability to remove filtered iron without requiring regeneration.
  • Catalytic oxidation by the media requires less contact time and bed depth.
  • Minimal labour and operational costs.
  • Spherical beads prevent compaction of the media.
  • Higher service velocity at lower iron content, resulting in cost reduction.
  • Suitable for a wide range of temperatures (20-45°C).
  • Compatible with high Total Dissolved Solids (TDS) levels (up to 2500ppm) and lower alkalinity levels.
  • Easily adaptable to various applications.
