Manganese Greensand for Filters
|Publication Date:||24 January 2015|
This standard describes manganese greensand used in pressure and gravity filters to remove dissolved iron, manganese, radium, arsenic, and hydrogen sulfide. It discusses the placement, handling, preparation, and regeneration of manganese greensand media. Although manganese greensand filters frequently employ gravel and anthracite filter materials, they have been omitted from this standard with reference to the document ANSI/AWWA B100, Standard for Granular Filter Material, which covers these materials in detail.
The purpose of this standard is to provide the minimum requirements for manganese greensand filter media, including physical, chemical, packaging, shipping, and testing requirements.
