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.

and EC50 Series
Hayward Perflex D.E. filters provide the deepest, most
comprehensive clean, removing microscopic dust and pollen
as small as one micron – 100 times smaller than a grain
of salt.
Providing crystal clear, sparkling
water at an economical price, it the Perflex D.E. Filters
have been proven reliability, and energy savings over
many years, Perflex has set the standard in swimming
pool filtration by incorporating the patented Flex-Tube™
design in combination with D.E. filter powder – the
most efficient dirt remover known for pool filtration.
The result is superior water clarity, extended filter
cleaning cycles – and no backwashing required.
- Captures all dirt, removing
microscopic dust and pollen as small as one micron
- Traps algae
- Efficient one-pass cleaning
power
- No Backwashing – "bumping"
activates Flex Tubes™ repositioning dirt and D.E.

There are three popular methods of
filtration – Sand, Cartridge, and Diatomaceous Earth (D.E).
Sand
In this method, impurities are extracted from the water
utilizing sand to collect and attract the debris. Sand
filters must be backwashed (running it in reverse) to
unload the water waste. This is a manual process that
must be performed every few weeks.

Cartridge
Cartridge filters have a greater surface area than sand
allowing for smaller particles of debris to be trapped and
filtered. Cartridge filters are designed to run at lower
pressure than sand which puts less backpressure on the pump,
providing more flow and turnover. Correctly sized cartridge
filters should be cleaned once or twice a season by simply
hosing them off.

DE
Diatomaceous earth is mined and is the fossilized exoskeletons
of tiny diatoms. This method of filtration is the most effective
by trapping debris as small as 2 - 5 microns. Once the pressure
rises, the filter is backwashed just like a sand filter
and then "recharged" with more DE powder.
