This term is specifically applied to shallow marine sediment that contains noticeable quantities of rounded greenish grains. In the years prior to world war ii researchers in the water treatment. Green sand filters use a specially formulated filter media made from a naturally mined form of glauconite greensand. Manganese greensand is the single best method for removing these contaminants in higher concentrations and when other filter media will not quite work.

Greensand filter for wells. There are three main types. An easy procedure to follow is to mix one pound of kmno4 per five gallons of water. Chemical treatment and filtration.

The minimum depth of the greensand bed is 24 30 inches when using the ir method and 18 20 inches when using the cr method.
