DIRM 412
Iron Removal Resin Media
DOSHION DIRM 412 is resin media for effectively removal of dissolved iron from ground water. DOSHION DIRM412 is an insoluble resin media which enhances the oxidation of dissolved iron and converts the soluble iron(Fe++) into insoluble Ferric (Fe++) which produces ferric hydroxide and can be filtered through resin media.DOSHION DIRM-412 effectively removes the iron present as a ferrous iron, however colloidal iron, soluble organic iron and bacterial iron are also removed comparatively to a lesser extent. Regeneration of resin media can be done by simple back washing with raw water .
The Advantages of DOSHION DIR-412 :
• It is an insoluble resin media simply acting as an iron filter .
• Granular shape & Particle size is to suit flow dynamics of a treatment plant.
• Longer life due to regenerable nature and hence very economical over the consumable conventional media.
• High efficiency to remove iron as compare to conventional media, almost iron free water (<0.3 ppm) can be obtained.
