Maximising pool hygiene with UV technology: A smart solution
For those involved in pool design and construction, from homeowners to architects and contractors, maintaining pristine water quality while prioritising sustainability is a growing concern. While chlorine has been the traditional method of sanitisation, UV pool systems are revolutionising the industry by offering an innovative, eco-friendly solution. By incorporating UV technology, pool designs can achieve enhanced hygiene, improved efficiency, and a more enjoyable swimming experience, setting new standards in modern aquatic spaces.
What is a UV pool sanitiser?
A UV (ultraviolet) pool sanitiser is an advanced filtration system that uses high-intensity UV light to neutralise bacteria, viruses, and algae in pool water. Installed within the filtration system, it acts as an extra layer of sanitation, reducing the need for high levels of chlorine or bromine while ensuring superior water clarity and safety.
For architects and contractors, incorporating UV sanitisation into pool designs demonstrates a commitment to sustainability and modern technology while providing clients with a low-maintenance, high-performance water treatment solution.
How do UV pool sanitisers work?
1. Water circulation – Pool water is pumped through the filtration system and into a UV chamber before being returned to the pool.
2. UV exposure – As the water passes through the UV chamber, high-intensity ultraviolet light targets bacteria, viruses, algae, and other harmful microorganisms.
3. Disinfection – The UV radiation disrupts the DNA of these microorganisms, effectively deactivating them and preventing further growth.
4. Cleaner, safer water – The treated water is then reintroduced into the pool, significantly reducing harmful contaminants and improving water quality.
The benefits of UV pool sanitisers
- Reduces chemical usage – UV systems help lower chlorine or bromine use, reducing skin and eye irritation and eliminating strong chemical smells.
- Highly effective against bacteria & viruses – UV light can neutralise chlorine-resistant pathogens like Cryptosporidium and Giardia, offering an extra layer of protection.
- Improves water quality – By breaking down organic contaminants, UV systems help maintain clearer, cleaner water with fewer chemical by-products.
- Eco-friendly option – Less reliance on chemicals makes UV sanitisation a more environmentally friendly choice for private pools.
- Reduces Chlorine by-products – UV breaks down chloramines, which are responsible for unpleasant smells and irritation, making swimming more enjoyable.
Key considerations when installing a UV pool sanitiser
- Not a standalone solution – While UV is highly effective, it doesn’t completely replace chlorine or bromine. A small amount of residual sanitiser is still required to maintain water safety.
- Initial installation cost – While UV systems can lead to long-term savings, the upfront cost may be higher than traditional sanitisation methods.
- Requires routine maintenance – UV lamps need periodic replacement, and the system must be kept clean to ensure optimal performance.
- No residual protection – Unlike chlorine, which remains in the water to continue fighting bacteria, UV only sanitises water as it passes through the system. Additional chemical treatment is needed between filtration cycles.
