Greensand filtration

Greensand filtration This step removes soluble iron and manganese (and sometime hydrogen sulfide). [Pg.189]

This type of filtration is typically only used on well water sources. In some cases, media filtration is not required prior to greensand filtration. [Pg.189]

Iron/manganese - oxidation, greensand filtration, iron filter, aeration... [Pg.411]

Others recommend treatment to remove the compound. Hydrogen sulfide can be removed or reduced from RO feed water using some iron filters (such as manganese greensand and Filox, see Chapter 8.1.5) or a complicated combination of oxidation, coagulation and filtration, sulfite addition, and rechlorination.9... [Pg.131]

Waters that may be contaminated with high concentrations of turbidity may want to consider a top layer of anthracite to capture these solids. This protects the greensand and ensures that the greensand is free and clear to proceed with oxidation and filtration of metals. A 15 - 18-inch layer of anthracite is recommended. [Pg.162]

Potassium permanganate commonly used in conjimction with greensand filters for iron oxidation and filtration. [Pg.211]
