Mno Mno2 Filtermedia

Manganese Di Oxide - Filtermedia.

In general, the most favoured method today for the removal of Iron and Manganese is catalytic oxidation. Currently two types of catalytic media are used; Manganese Greensand, a treated zeolite and natural Manganese Dioxide. There are considerable differences in the economics and methods of use between these two materials. The application of Manganese Greensand requires the replacement of the whole filter bed, regeneration with potassium permanganate along with its storage and dosing facilities, monitoring and manning. Manganese Dioxide requires only partial replacement of the filter media with no chemical dosing and regeneration apart from chlorination, and no monitoring to ensure efficient working.

Normally, between 10% to 20% of MnO 2 by volume of the filter sand is added to the filter. This is usually placed on top of the sand bed until thoroughly mixed, as it is important that the water passing through the filter comes into contact with as much MnO 2 as possible for as long a period as possible. Any precipitated iron or manganese adheres firmly to the catalytic grains without impairing their activity. The manganese Dioxide particles thus act as a filter of suspended solids as well as catalytically absorbing toxic metals.

Sunflame Fuels manufactures quality Filtermedia and has a well acclaimed European market with product well approved over years. With a well set up infrastructure and availibility of quality and graded raw material, Sunflame is able to deliver quality product with timely deliveries.

The company is now looking for the American and Australian Potable Water Filtration Market.
