About DE Filters

Diatomaceous earth is a porous powder with microscopic openings, that, when magnified, look like tiny sponges. Clear water can pass through these openings, but particles, as small as one to three microns, are trapped during the first pass through the media. D.E. filters have internal elements that become coated with D.E. It is this 'filter cake' that strains dirt, dust, algae, and some forms of bacteria from the water. Similar to sand filters, when D.E. filters become dirty, they are cleaned either by backwashing, or regenerating and draining the clogged D.E. to the waste line. To restore filtration, a fresh charge of D.E. is added to the filter. For sparkling, clean pools; step up to Hayward D.E. filters.
