Chemical Feeders
Chlorinators and
chlorine feeders
make sanitizing your pool a breeze.
Just fill the chlorine feeder with
chlorine, and choose your setting.
The idea of not having to add
chlorine to the pool for a couple of
weeks is very appealing to many
people. The type of chemical feeder
you use depends on the type and size
of pool you have. Below is a summary
of the major types of chlorinators
available for the residential
market.
Erosion Chemical Feeders
One of the most common types of chlorine
feeders is the erosion feeder. Solid,
compressed chlorine or bromine, (In the
stick or
tablet form) are placed in the
feeder .
Water
flows over the chlorine and dissolves it
for a slow release. Chlorine
or
bromine is
then infused into the water.
These feeders can be adjusted to
regulate the amount of sanitizer induced
into the water. There are two common
types of erosion chemical feeders.
Floating chemical feeders are filled
with bromine or chlorine tablets and
placed in the pool or spa. They float on
the surface allowing the water to come
in contact with the chlorine, therefore
dissolving the tablets slowly to
continuously add a small amount of
chlorine or bromine into the water. The
floating feeder can usually be adjusted
by turning the adjustment collar on the
bottom of the floater. The floating
chlorinator is perfect for above ground
pools and spas.
Another type of erosion feeder is
installed at the filter system. It looks
like a canister that (unlike a floating
chlorinator), requires a certain amount
of pressure supplied by the circulation
system to dissolve the chlorine or
bromine tablets or sticks. The flow and
amount of chlorine introduced into the
water is regulated by a flow control
dial. This type of feeder can plumbed
directly in line on a horizontal pipe at
the filter system, or installed off
line. The off line models are supplied
by a hose that feeds untreated water
from the pump discharge, into the
chlorinator.
The water is then “pushed” over the
chlorine or bromine tablets, dissolving
them slowly. The newly chlorinated water
is then “pushed” out of the chlorinator,
through another hose, and is injected
into the return line. The freshly
sanitized water is then returned to the
pool through the return line. It is very
important that granulated chlorine is NEVER
added to an erosion feeder. This could
cause injury or even death!!
Liquid Chlorine Feeders
Probably, the most commonly used type of
chlorine in the world is is liquid
chlorine (Sodium Hypochlorite). This
chlorine is used on commercial pools
that require a large amount of chlorine
to maintain a safe sanitation level.
Liquid chlorinators are usually mounted
over a vat filled with liquid chlorine,
and have their own small electrical pump
which pumps liquid chlorine from the vat
into the pool's plumbing by way of an
injector. With an output control dial
and a time clock incorporated into these
chlorinators, it is easy to regulate he
amount of chlorine injected into the
water and the final chlorine reading on
the test kit. These types of
chlorinators are rarely used in the
residential market. |
