THE COPPER-SILVER SYSTEM
A common and very effective method of purifying swimming pools is
to use electronically produced copper and silver ions. It was previously
promoted that copper was the more efficient algicide and silver the
more effective bactericide. More recent studies have shown each to
be highly effective in the control and killing of both bacteria and
algae. Together they give superior results.
This method has the advantage over chlorine of remaining very stable
in swimming pools. The pool will stay sanitized for days or weeks
with the system turned off and no additional copper or silver being
Copper and silver are not absorbed through the skin, therefore ,
are not carried out of the pool by swimmers. They are also not affected
by sunlight and actually become slightly more effective as the water
is heated or the pH increases.
Copper and silver are safe. At the normal recommended levels of
copper in a swimming pool, a person would have to drink over two
gallons of pool water to get the amount of copper in one vitamin
pill. A glass of EPA approved tap water could have five times as
much copper in it as a glass of swimming pool water. The tap water
could also have five times as much silver as a glass of pool water.
The Environmental Protection Agency completely removed any limits
on silver in drinking water in 1989 because they said it presented
no hazard to human health.
ELECTROLYTIC MINERAL ION SYSTEMS
Electrolytic mineral ion systems are a proven, effective non-chemical
method to help control bacteria, algae and viruses. Advantages include
improved water quality, effective algae and bacteria control, improved
sanitation, reduced chemical usage, automated operation and an environmentally
friendly method of water sanitation.
How it Works: This is a very basic explanation of how copper and
silver works. Both have some algaecidal and bactericidal properties.
Copper has the ability to pierce the protective outer membrane of
a cell and disrupt enzyme balance, as well as allowing other bactericides
and algaecides access to the susceptible part of the organism. Silver
is effective because of its capabilities of interfering with DNA
production and accelerating the death phase. Although lethal to bacteria
and algae, this process is completely safe to humans. A multitude
of scientific tests have been done showing the effectiveness of copper-silver
ion systems in different areas including swimming pool and spa applications.
Ozone destroys bacteria, molds,
and mildew, eliminates spores, yeast, and fungus, deactivates viruses
and cysts, and will oxidize and destroy oils and other contaminants
in water. Ozone will reduce or eliminate the need for high levels
of harsh chemicals such as chlorine and bromine, significantly reducing
maintenance costs. Ozone leaves no unpleasant chemical taste and
is less corrosive than chlorine. Ozone dissolved in water will not
irritate skin, nose, or ears, nor will it dry out or leave a chemical
on skin. Ozone does not affect the pH balance of water like traditional
chemical treatment methods.
Ultraviolet (UV) light can be used as an alternative sanitizing method
to very effectively destroy microorganisms in swimming pool water.
Up to 99.9% of the microorganisms can be destroyed, as the pool
water passes through the UV unit. This dramatic reduction, in the
microbial populations, helps to better maintain proper sanitary
pool water conditions: reducing the amount of chemical sanitizer
needed to maintain proper, sanitary water quality and keep the
underwater surfaces free of bacterial or algal growth. A UV Sanitizer
must be used in conjunction with another sanitizing product: chlorine,
ionizers or mineral purifiers. In addition, oxidation of waste
products must be accomplished with the use of chlorine, ozone,
shock or hydrogen peroxide. Most commonly a UV Sanitizer is used
with chlorine or bromine and can reduce their usage by a considerable
amount. Typically, an Ultraviolet Sanitizer is plumbed inline and
operates with the filter pump cycle. Water passing through the
cell is efficiently sanitized, as the UV light passes through the
microorganism's cell membrane.
You can add UV Sanitizing and an Ozone Generator, but as two separate
units. It will virtually assure you that the return flow will be
devoid of living algae and bacteria. However, the pool walls and
water can still support algae and bacteria. Keeping a low level of
chlorine, about 1 PPM, will prevent growth in the pool and on the
walls. The ozonator will carry the burden of oxidizing wastes and
very little chlorine will actually be required. The odorous form
of chlorine will be destroyed, as the water returns to the pool.
There should be little or no sensation of chlorine. The fact that
you will be able to maintain this low level of free chlorine, with
only minimal amounts of chemicals, will act as conformation that
proper conditions exist and that everything is functioning properly.
CHLORINE GENERATORS AKA SALT SYSTEMS
These systems are actually miniaturized chlorine manufacturing
plants: the same technology is utilized. The devices are plumbed
in-line and work by electrolytically converting salt, in the pool
water, into chlorine as it passes over specially coated titanium
electrode plates. Salt must be added to the pool prior to start up,
as directed. Thereafter, salt needs be added occasionally, to replace
that lost due to splash out, rainfall, pool leaks.
Salt alone doesn’t keep water clear
and free of algae. Ocean life depends on algae. Chlorine generators
simply generate chlorine gas and hydrogen gas from salt and water
at the expense of your power bill. Once mixed with pool water,
chlorine gas produces the exact same active sanitizer as the chemical
chlorine you are currently using.
This chlorine will continue to burns eyes, dry skin, and bleach
bathing suits. Chlorine generated from salt is not a chlorine alternative.
