Γ-Membrane Media
The  Γ-Membrane is a Γ-FeO(OH) membrane attached on the surface of a carrier material. It has  a high contact oxidation power. It increases the rate oxidation of iron and manganese. Normal rate of oxidation for the other media takes 1 to 2 hours which is also affected by pH and other chemical reactions. But the Γ-Membrane media takes only 3 to 6 minutes.
The following is the Γ-Membrane media for filtering of iron and manganese:
