How a D.E. Filter Works
When diatomaceous earth (D.E.) is introduced into the filter system,
it coats the filter cloth. As water passes over the filter grids, the D.E.
particles capture even the smallest suspended dirt particles. When
cleaning is needed, the water flow is simply reversed and contaminants
are backwashed away.
