Cartridge Filters
Cartridge
filtering is a simple process wherein water passes through a
cartridge filter while dirt is kept out at the exterior of the
device. The
filters need to be kept clean so that the cartridge is better able
to catch
the large particles, and the smaller particles can be filtered
through.
Pressure washing is the best way to clean the cartridge. The element
is
removed from the filter and then washed by the garden hose.
It has only been in the past several years that cartridge filtration
has
become accepted by spa and pool owners, even though the process has
been
around for quite a long time. Cartridge filtration is a simple
method with
easy maintenance which has increased its growth and acceptance among
pool
and spa owners and caretakers.
It is quite easy to determine when your cartridge elements need
cleaning,
even though there are no electrical parts to stop working. You will
know the
element needs cleaning when the spaces and pores of the material
surface
plug up due to continued use.
The causes of plugging up a filter in a spa are generally the result
of body
oils and perspiration, soaps, chemical and other such particles. In
a
swimming pool the clogs are usually a result of suntan lotions and
outside
debris, such as dirt, leaves and algae.
Even though you properly clean and maintain your swimming pool or
spa
filter, you can establish that the cartridge needs to be replaced
after
determining the following conditions: low water flow rate and degree
of
pressure; a tear in the material or center core; brief time between
cleanings. All of these conditions depend on correct water chemistry
of your
pool or spa and utilizing a proper maintenance schedule.
The filter elements are somewhat fragile in that they are plastic
and
require proper maintenance and treatment. You may enhance the life
of your
cartridge in the following ways: reading the instructions to learn
how to
properly clean the elements; do not use a steel brush to clean the
system;
use an enzyme treatment (this will break down oils); do not let the
differential pressure exceed 8psi between cleanings; properly
balance and
maintain the chemistry of the pool or spa; alternate between two
sets of
cartridges when cleaning.
