(25L OR 31.5KG/BAG)

Manganese Green Sand is a specially processed medium for iron, manganese, and hydrogen sulphide removal. This premium non-proprietary filter medium is processed from glauconitic green sand on which a shiny, hard finite thickness manganese oxide coating is formed and is firmly attached on every grain by a controlled process.

It is one of the most popular ways to filter water when hydrogen sulfide, iron or manganese are a concern. It began being used in filtration systems in the middle of the twentieth century. Since that time technology has advanced the process but the overall fundamentals remain the same.

The Manganese Green Sand has been manufactured from glau conite green sand and it can be used for removal of iron, manganese or it’s combined together. It can be used in open gravity filtration or closed pressure tank filtration system with or without any chemical added. However, base upon the quality of inlet water oxygen, chlorine and KMnO4 probably might be injected initially before contact to Manganese Green Sand.

Due to its catalyst power of MnO2 on the Green Sand bead, it could oxidize iron, manganese in soluble form to insoluble (precipitation) form. These insoluble complexes actually retain between the depths of media and could be discarded during backwashing step later. By the way, after oxidation, MnO2 will be converted to Mn2O3 so far. KMnO4 exactly have been using as regenerant in which it could restore oxidizing power of Manganese Green Sand. So, exhausted Mn2O3 will become fresh MnO2 again.

In short, when filtering iron, the Manganese Green Sand is used in a process called continuous regeneration. For this process, a solution is fed into the water supply that oxidizes the iron. The oxidized iron is then filtered out by the Manganese Green Sand. A process called intermittent regeneration is used when using Manganese Green Sand to filter manganese.

The Manganese Green Sand is packed in polyethylene bag that can prevent moisture from circumstance. This packing contains exactly 31.5 kgs or 25 litre.
