Many pool professionals consider
D.E. filtration to be the finest, because it is capable of removing
smaller particles than either sand or cartridge 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. All D.E. filters have internal elements that become
coated with D.E. It is this 'filter cake' that strains dirt, dust, algae
and even some forms of bacteria from the water.
Here
is the ironic part . . . diatomaceous earth comes from diatoms which are a
golden brown form of algae!! Diatoms are a tiny one-celled plant
which grows and multiplies by the billions in water all over the
earth. The dead and discarded shells form thick deposits on the
bottom of the ocean and after long ages, the shell deposits turn into a
porous mass called diatomite (also known as diatomaceous earth). The
sparkling clear water produced by a DE filter is only possible because
of . . . dead algae . . . imagine that!!
