How does a diatomaceous earth filter work?

When diatomaceous earth is introduced into the pool filter system, it coats the filter cloth. As water passes over the filter grids, the DE particles capture even the smallest suspended dirt particles. Water passes through a series of DE-coated grids. Under a microscope, DE looks like a collection of tiny sponges.

Simply so, what is a diatomaceous earth filter?

Diatomaceous earth (DE) is a filtration method in which diatomaceous earth is applied to precoat a mesh screen (called a septum) prior to each filter run. DE consists of a powdered media, made of almost pure silica manufactured from diatoms - the fossilized skeletons (frustules) of fresh water, unicellular algae.

Furthermore, what does diatomaceous earth do in a pool filter? A Diatomaceous Earth (DE) Filter cleans your pool water by passing the water through a set of normally 8 grids. Each of these grids is covered with a layer of DE powder.

As the pressure gauge on a D.E. filter increases, flow rate decreases.

How long do DE pool filters last?

Pool-filter cartridges can run for about 2,000 hours in a filter pump. Usually, filter cartridges have to be replaced once every one to two years. The filter, however, will not last as long if you enter the pool with suntan lotion, deodorants, hair-care products, and other chemicals.
