Ultraviolet (UV) Pool Treatment: Pure Water with Less Chemicals

Ultraviolet light pool treatment is a disinfection technology that uses UV-C light to eliminate microorganisms in the water. Unlike traditional methods that rely heavily on chlorine and other chemicals, UV disinfection can reduce their use by up to 80%, providing healthier water, free of odors and irritation.

In addition, swimming in this type of pool enhances the user experience and is especially beneficial for swimmers with skin problems.

If you are looking for an efficient, environmentally friendly and easy to maintain system to improve the water treatment in your pool, ultraviolet pool cleaners are one of the best solutions available.

Why choose an ultraviolet light disinfection system?

UV systems offer multiple advantages compared to conventional chemical treatments: Efficient and Natural Disinfection UV-C light penetrates the DNA of organic matter (microorganisms such as bacteria, viruses, algae) preventing their reproduction and eliminating them without the need for chemicals. The ultraviolet light eliminates a large part of the organic matter present in the water. This reduces the amount of free residual chlorine needed, since the organic load has decreased. However, it is important to maintain an adequate level of residual free chlorine so that, when bathers enter the pool, it can act and ensure effective disinfection. We recommend a minimum of 0.5 ppm.

Reduction of Chlorine or Bromine levels

This is directly related to the previous point. Ultraviolet light significantly reduces the organic matter present in the water, which reduces the amount of chlorine or bromine needed. With less organic matter, it is not necessary to maintain such a high level of disinfectant.

This reduction has two main advantages:

• The characteristic smell and taste of chlorine is minimized, avoiding discomfort for bathers.
• Skin and eye irritation is reduced, providing a much more pleasant bathing experience.

More crystalline and odorless water

By preventing the accumulation of chloramines and other chemical residues, the water remains clearer, without strong odors or greasy residues.

Increased Safety for Bathers

By eliminating the need for high concentrations of chlorine, water becomes healthier and less irritating to skin, eyes and hair. Ideal for people with allergies or sensitive skin.

Ecological and Sustainable System

It does not generate residues or alter the chemical balance of the water. In addition, it reduces the amount of chemicals that end up in the environment.

Low Maintenance and Easy Installation

Only requires periodic replacement of the UV lamp (every 2-3 years depending on the model). It is installed in the filtration circuit without the need for complex modifications.

How does UV treatment work in swimming pools?

The UV disinfection process is simple but highly effective. It is integrated into the pool filtration system and works as follows:

• The water circulates through a UV holder, which contains an ultraviolet light lamp.
• UV-C light penetrates the cell walls of microorganisms, destroying their DNA and preventing their reproduction.
• The water returns to the pool with a substantial reduction in organic matter.

Is UV light enough to keep the pool sanitized?

Although UV systems eliminate bacteria and viruses, they do not leave a disinfectant residue in the water. For this reason, it is recommended to combine them with a minimum dose of chlorine or bromine, ensuring complete disinfection.

Compatibility with other treatments

• Saline chlorination: Ideal for those who want a pool with minimal chemical maintenance. We recommend saline chlorinators with ORP control to maximize the advantages
• Bromine: Alternatives for those who prefer to avoid the use of chlorine.
• Chlorine: In the case of chlorine use, the ideal is to use Redox dosing pumps. https://www.quimipool.com/en/13159-metering-pump-seko-poolmatch-redox-15-l-h-with-modbus.html

Main Features of UV Sterilizers

Different capacities depending on pool volume → There are models designed for small pools up to large commercial installations.

• High-performance lamps → High-intensity UV-C technology, with a lifetime of 9,000 to 12,000 hours.
• Low energy consumption → High disinfection capacity with reduced power consumption.
• Compact design and easy installation → Integrate into the filtration system without structural modifications.
• Corrosion resistant housing → Industrial grade stainless steel or PVC materials ensure durability. In salt chlorination installations, UV systems should be made of plastic.
• Minimal maintenance → Only requires lamp replacement and occasional cleaning of the reactor.
