The pool construction is often described as the foundation
of every pool, but as we all know a simple foundation is not enough to keep
things functioning. This is where the pool equipment comes into play. As we are
all aware the water in the pool must circulate through the filtration system in
order to remove any traces of impurities (dirt, bodily fluids etc.). During a
normal operation of the filter system, the water from the pool flows through
one or more floor drains located on the bottom of the pool and through one or
more skimmers that draw water from the surface of the pool. In this way the
water is kept constantly clean. Pool filters are responsible for the mechanical
removal of impurities from the water in the pool and they are an essential part
of each pool. Without pool filters it is almost impossible to keep the water in
a good condition for more than two weeks. With the advance of technology
several different types of pool filters are now available on the market and
each of them has its own advantages and disadvantages.
Most of the pool filters are sand filters. These filters
have a large tank which is usually filled with quartz sand that can attract
dirt in the best way because of its specific texture. Pool filters are mostly
made of materials such fiberglass, reinforced polyester etc. During the process
of filtration, the dirty water from the pool comes in through the inlet pipe
filter, through which the dirty water flows evenly over the entire surface of
the filter. While gravity pulls the water down through the sand to the bottom
of the filter, sand collects tiny particles of dirt and attracts litter. The
filtered water flows out through the outlet of the pipeline which is located at
the bottom of the tank. After a while, the accumulated dirt and residues of
impurities in the sand slow down the water flow. The pressure of the filter
gives us a clear signal that there is an internal blockage in the filter caused
by the dirt and that it is time to clean the filter. In order to do that, a
person who takes care of the pool should set the 6-way valve on the filter from
filter mode to flush mode.
Instead of sand filter, some pool system use cartridge
filters. In such filters dirty water is contained in a cartridge that is made
from corrugated paper or polyester fabric. In order to clean this system,
simply remove the cartridge and rinse it with a regular water hose. Cartridges usually last for more than 5 months.
According to many experts the so-called DE pool filters are
the most efficient filters today. They use a pressure gauge to signify a need
for back-washing. With the help of a DE powder the pool is thoroughly cleaned
and even microscopic particles are eliminated from the water.
Which of these types of pool filters is best for your
depends on your requirements. If you are looking for a lasting solution you can
choose the sand filter. If you want to save some money then you should take
cartridge filter into consideration. Finally, if you are looking for the safest
and most efficient filter you should purchase Diatomaceous Earth (DE) pool
filter.
