DESCRIPTION
Manganese sand is a granular type of filter media used in a filter tank to remove iron, manganese, radium, arsenic, and hydrogen sulfide in the tap water. Its main component is manganese dioxide, with a content between 35% and 90%. The black to brown-colored substance is a naturally-occurring mineral, it is one of the more popular and commonly used filter media to remove iron and manganese in water supplies.

SUGGESTED APPLICATIONS
MANGANESE SAND
--a ideal iron&manganese removal media for water treatment
How Does Manganese Dioxide Work In Water Treatment? Manganese dioxide works as a catalyst to improve water quality by removing iron, manganese and other contaminants in tap water from municipal water supplies and deep well. MnO2 is responsible for the chemical reactions occurring inside the filter system to remove iron, manganese, radium, arsenic, and hydrogen sulfide from the water source. These contaminants precipitate and get absorbed onto the granular filter media containing manganese dioxide. ADVANTAGES • Simple technology used, it is very easy to operate. • Not large area needed, low project cost • Workable in wide pH range for iron reduction • Long-term stability, low attrition and longer use life • No harmful effects may cause |
