Diatomite/ Diatomaceous earth filter aid powder
Diatomaceous earth (DE) is a filtration method in which diatomaceous earth is applied to precoat a mesh screen prior to each filter run. DE consists of a powdered media, made of almost pure silica manufactured from diatoms - the fossilized skeletons of fresh water, unicellular algae. DE filters are most suitable to treat waters with low bacterial counts and low turbidities.?
