Iron Removal Media
In Bhutan

We have our specialized range of water filtration systems and Iron Removal Media is one of them. It is highly regarded for removing traces of iron completely from water. It is uniform in size and has perfect composition. Our products have been coveted by clients based in Bhutan and abroad. We are a customer oriented organization and offer cost effective products for our clients.

Features:
Used for removing iron from water
Highly pure
Uniform in size

Water Treatment is done using the following procedures:
On contact with higher oxides of manganese on the green sand granules, the soluble iron and manganese are oxidized and precipitated
The hydrogen sulphide gets reduced by oxidation to an insoluble sulphur precipitate
Precipitates are thereafter filtered and removed by back-washing
When the oxidizing capacity power of the Manganese Greensand bed gets exhausted, then it has to be regenerated by using weak potassium permanganate (KMnO4) solution, which helps in restoring the oxidizing capacity of the bed
