Swimming Pool UV

Swimming Pool UV

Swimming Pool UV (Ultraviolet) is a robust filtration system that eliminates harmful microorganisms from pool water using light beyond the visible spectrum. Disrupting the DNA of algae, bacteria, and chloramines significantly reduces chemical usage while enhancing water clarity and safety. With benefits including reduced irritation and compatibility with various treatments, Swimming Pool UV offers a cost-effective and efficient solution for maintaining pristine pool water quality.

At 1st Direct Pools, we stock a range of fantastic UV systems, from the professional favourites Elecro Quantum to the classic Certikin and Blue Lagoon UV filters.

What is Swimming Pool UV? 

Swimming Pool UV (Ultraviolet) is a filter that generates light beyond the visible spectrum. When Shone onto certain chemicals, it triggers a reaction that eliminates harmful microorganisms within the pool water. 

The process starts with UV light moulding the cell DNA of algae spores and bacteria, preventing them from reproducing and multiplying within your pool water. UV light will also deactivate chlorine-resistant parasites like cryptosporidium and Giardia, breaking down chloramines and other organic pollutants by attacking their molecular structure. It effectively neutralises chloramines, also known as combined chlorine, improving water quality and reducing pool users' risk of irritation.

A Swimming Pool UV is unlike a Salt Chlorinator. While a salt chlorinator generates chlorine and allows it to remain in the pool water as a residual sanitiser, a UV system only treats the water that passes through its chambers. Therefore, to keep the pool water sanitised, you must add chlorine separately to your maintenance routine. The UV will eliminate algae, bacteria and chloramines, which means that the chlorine levels required are typically low, usually around 0.5 ppm, which is perfect if you are looking at an affordable way to reduce chemical usage. 

It's important to understand that a UV system does not work independently. Adequate turnover rates and proper water filtration are required to ensure high-quality pool water. Combined, these elements provide a much safer and more enjoyable swimming experience.

What are the Benefits of a Swimming Pool UV? 

  • It completely destroys all bacteria, microorganisms, and harmful pollutants, emitting only pure water and CO2 back into the pool.
  • It is the only technology that breaks down organic matter, such as suntan oils, urea, and pathogenic biofilm.
  • Drastically reduces chemical use and unwanted bacteria, pathogens and viruses. 
  • It creates visually clear and healthy pool water with exceptional clarity and brilliance.
  • It does not impact pH levels and is compatible with all other treatments, including salt electrolysis and seawater.

How Does A Swimming Pool UV Function? 

Pool water flows through UV light lamps in the Swimming Pool UV system.

These lamps can vary in spectrums of UV light and attack cell DNA, such as algae spores or bacteria, while some attack chloramines. The lamps are protected by a quartz glass sleeve, which can become clogged with contaminants, so a function has been built into the design to remove the contaminants from the sleeve. 

The lamps are available as low-pressure or medium-pressure. Low-pressure lamps deal with bacteria, and medium-pressure lamps deal with chloramines. The lamps have a typical lifetime of 8,000 - 10,000 hours. Sound pool UV systems will have an indicator that tells you when the lamp is nearing the end of its lifespan.
