About ionisers supplied and installed Swimming Pools Thailand shop

Copper ions behave as an algaestat and inhibit algae growth (see below), while silver ions behave as a bactericide killingbacteria.

Pool Ionization is not a stand alone sanitizer. Pool ionizers cannot oxidize organic matter effectively, so additional chlorine or non-chlorine shock treatment is necessary. There also is the potential for staining of interior surfaces. Copper can deposit itself on these surfaces, giving a blue-green color, {which isn't too bad to look at, some pool people like the color}. At  swimmingPoolsThailand we can tell you more.

Silver can react with sunlight, similar to the way photographs are produced, and create black stains on the plaster. Used properly, and not overused, electric pool ionizers won't stain. Use of a sequestering agent (Stain & Scale product) is recommended if you use one of these systems.



Copper and Silver ions reduce the amount of micro-contaminants in the pool water, which reduces your chlorine demand. Some owners use a pool ionizer continuously, and shock the pool weekly, eliminating the need for tablets. Frequent shocking however, may cause excess minerals to precipitate out of solution, depositing itself on pool surfaces.

Calcium hardness: TDS (total disolved solids) levels in a pool are recommended to be below 1000ppm, for a swimming pool mineral ionizer to work effectively. Hard water pools, with Calcium Hardness levels in excess of 500ppm may also need to clean the electrodes more often to remove scale deposits.

High water temperatures such  as in  tropical  climates, can reduce the effectiveness of the minerals to sanitize. When pool water temperatures exceed 80 degrees, more of a halogen sanitizer (i.e. Chlorine) may be needed to effectively maintain pool water clarity.

Totally harmless: Ionizers can reduce reliance on traditional chemicals, or provide additional power to your sanitation program. Copper and Silver ions are not harmful, even if the pool water is being swallowed, in such low levels. Too much copper can turn your hair green, especially for blonde swimmers. Too much copper can also stain your plaster or white plastic surfaces.
An ion is an atom, or group of atoms that possess an electrical charge. Ions exist everywhere and your pool is full of ions. It was discovered long ago that copper ions behave as an algaestat ,that is, they inhibit algae growth, while silver ions behave as a bactericide, that is, they kill bacteria.
 
A pool ionizer installed by  Swimming Pools Thailand is a device that uses electricity to produce these metal ions right in the plumbing, so they are dispersed into the water to do their work. Copper and/or silver electrodes are energized with a low voltage, DC current supplied from the equipment sub panel. The voltage is applied to two metallic electrodes placed in close proximity to each other within the plumbing pipe. The electrical current causes atoms of the copper or silver electrode to lose an electron and become cations. These cations are drawn towards the opposite electrode, but are swept away by the rushing water passing by. After this introduction in the water, these ions float dissolved in water until they encounter a microorganism.
 
Pool Ionization is not a stand alone sanitizer. Pool ionizers cannot oxidize organic matter effectively, so additional chlorine or non-chlorine shock treatment is necessary. This can be done byadding Purpool for a competely chlorine free sysyem, or by installing a NAKED fresh water system.

Copper as a sanitiser

Copper-alloy touch surfaces have natural properties that destroy a wide range of microorganisms (e.g., E. coli O157:H7, methicillin-resistant Staphylococcus aureus (MRSA), Staphylococcus, Clostridium difficile, influenza A virus, adenovirus, and fungi). Some 355 copper alloys were proven to kill more than 99.9% of disease-causing bacteria within just two hours when cleaned regularly.

The United States Environmental Protection Agency (EPA) has approved the registrations of these copper alloys as "antimicrobial materials with public health benefits"; that approval allows manufacturers to make legal claims to the public health benefits of products made of registered alloys. In addition, the EPA has approved a long list of antimicrobial copper products made from these alloys, such as bedrails, handrails, over-bed tables, sinks, faucets, door knobs, toilet hardware, computer keyboards, health club equipment, and shopping cart handles (for a comprehensive list, see: Antimicrobial copper-alloy touch surfaces#Approved products).

Copper doorknobs are used by hospitals to reduce the transfer of disease, and Legionnaires' disease is suppressed by copper tubing in plumbing systems. Antimicrobial copper alloy products are now being installed in healthcare facilities in the U.K., Ireland, Japan, Korea, France, Denmark, and Brazil and in the subway transit system in Santiago, Chile, where copper-zinc alloy handrails will be installed in some 30 stations between 2011–2014.
