Diatomaceous Earth

Other Names: Diatomite, kiseselguhr, filter acid

Soft earthy rock composed of the siliceous skeletons of small aquatic plants called diatoms. Sold as a powder which is able to absorb 1.5 to 4.0 times its weight of water.

Remarks: Diatomaceous earth is used for filtration, clarifying an decolorizing, as a mineral filler, thermal insulation, as an absorbent, an abrasive and as a source of silica in chemical production.

Pump Notes: Diatomaceous Earth is always handled as a mixture with another liquid. Pump construction varies based on the liquid. Diatomaceous earth is mildly abrasive and a pump must be able to handle this.
