Sand Filters, by HAYWARD High-rate sand filters
use a special filter sand, normally .45 to .55 mm (also known as pool
grade #20 silica sand), because it has sharp edges that serve to
separate particles, allowing filtration to take place. They operate on
the basis of "depth" filtration; dirt is driven through the
sand bed and trapped in the minute spaces between the particles of sand.
Initially, a clean sand bed will remove larger particles, and then, as
the bed starts to load up with dirt, it will remove finer particles. |

Cartridge Filters, by
HAYWARD When water passes through a cartridge filter, dirt is screened out at the surface of the cartridge element. When clean, the element will trap larger particles, with finer particles being filtered out as the pores of the element become clogged by the larger debris. The cartridge element can be removed and cleaned by pressure washing inside and out with a garden hose Click here to learn more about Hayward's line of Cartridge Filters |

Grid DE Filters, by HAYWARD Many pool professionals consider D.E. filtration to be the finest, because it is capable of removing smaller particles than either sand or cartridge. 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 some forms of bacteria from the water. Similar to sand filters, when a D.E. filter becomes dirty, it is
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. |
