Ultraviolet Pool Systems
In current years, the requisite for additional hygiene in public pools have become very distinct. Maintaining recreational pool water safe for swimmers most times necessitates more than the ordinary halogen-based sanitizer, such as chlorine, thus introduction of Ultraviolet (UV) Light Secondary Disinfection Systems. Some residential pool owners also use Ultraviolet pool systems in sanitation to improve general outcomes and minimize chlorine use.

Essentials of Ultraviolet Pool Systems
Wavelength
UV light is a range of short wavelengths of light 10nm – 400 nm and invisible to the naked eye.
Medium-Pressure UV Light Systems
Characterization of Medium-Pressure UV Light Systems is by the UV light spectrum in which they function. They function in a wavelength range of about 250 nm-600 nm. The lamps function at temperatures above 1,500 degrees Fahrenheit. In this range of wavelengths, UV light can react with various chemicals in water and deactivate chlorine sanitizers. This makes the process expensive due to the high volumes of sanitizers needed.
Low-Pressure UV Light Systems
This is characterized by the light spectrum in which they function. The wavelength range required to function is narrow at around 190 nm to 254 nm. The wavelength of 254 nm is suitable for the destruction of chloramine. This wavelength does not affect free chlorine and operates at 140 degrees Fahrenheit, making it cost-friendly to operate.
Secondary Disinfection UV Light Systems
Secondary Disinfection UV Light Systems are necessary on any increased risk aquatic venue as explained in ANSI/APSP/ICC-11 2019.
The explanation for this is that some pathogens like Cryptosporidium resist halogen-based sanitizers. A single pass through the reactor can make the UV light systems inactivate the pathogens. Medium-Pressure UV Light Systems are mainly used for secondary disinfection, though Low-Pressure UV Light Systems can also be applicable.
Supplemental Disinfection UV Light Systems
For Supplemental Disinfection UV Light Systems, installation can be on any aquatic venue, not only on increased risk aquatic venues. These ultraviolet pool systems inactivate the majority of the waterborne pathogens aside from Cryptosporidium. Most Supplemental Disinfection UV Light Systems are medium-pressure systems.
Water Conditioning Device
UV light systems are the latest addition to UV light products and aren’t sanitizers. They use low-pressure UV lamps functioning at 254 nm. Compared to the Low Pressure UV Pool Systems, Water Conditioning Devices aren’t meant for use as either supplemental or secondary sanitizers but instead to improve water and air quality in indoor pools.
UV Light Dosage is the Key
Whether a secondary, supplemental, or water conditioning device, the quantity is the most significant factor.
UV dosage relies on three important things:
Ultraviolet Transmittance (UVT) of the water
Contaminants like iron interrupt the transmission of UV light through water, despite the pool water appearing clear.
The power of the UV lamp
The amount required to get rid of monochloramines is 60 mj/cm2 for indoor pools and 40 mj/cm2 for outdoor pools.
The rate of the water flow through the UV pool systems
If the rate is slow, there is more contact time at the point of exposure to the UV light, hence accomplishing a higher dosage.
Different microorganisms require varying dosages for their deactivation. In most cases, UV light reacts faster at deactivating microorganisms than the advisable amount of sanitizer. Nevertheless, the common cold virus is resilient to UV light but can be easily deactivated by recreational water sanitizers.
The rate of water flow affects the UV system dosage. Thus, balancing suitable amounts of sanitizers and UV light systems at required flow rates can aid in providing a safe swimming environment.
Its application
UV treatment is a speedy physical process. In a UV disinfection process, pass water through a chamber containing a UV lamp. The bacteria in the water get exposed to the UV radiation generated by the mercury arc UV lamp. The radiation penetrates a microorganism’s cell wall, making it unable to mutate and damage its DNA. For this reason, it is unable to reproduce or function, making it harmless.
Most local codes will need a Secondary UV Light System installed to guarantee swimmer safety. Water conditioning UV light systems are becoming popular for indoor pools. This is because of their effectiveness in getting rid of stubborn chloramines; therefore helps improve the air quality for swimmers. UV products are normally used with spray pads as they are often categorized as increased risk aquatic venues because of their use by kids.
Maintenance and precautions
- Maintenance is imperative in ensuring the proper working of UV light products. Medium-pressure units need ultimate care since they function at extremely high temperatures. For the glass sleeve containing the UV lamp, it is usually coated with calcium and other contaminants. These components, at times, have wipers to clean the sleeves automatically. Lamps also require constant replacement. The necessary maintenance raises the expenses on operation and energy use.
- Low-pressure UV light products need lesser care. These lamps can function longer than medium-pressure units before necessitating a replacement. They are cheaper and also in the operating cost.
- It is essential to adhere to all applicable electrical codes and safety measures when using UV equipment. Before servicing or making electrical connections, switch off the power at the main source. Follow the manufacturer’s instructions when operating and maintaining the ultraviolet pool systems.
- UV light can lead to serious eye and skin damage. Don’t handle or glare at a functioning UV lamp.

Blue Wave Recall on Over 13,000 Above Ground Pools
Blue Wave has issued a recall affecting multiple above-ground swimming pool models after federal safety officials identified a potential drowning hazard involving children.
The recall, announced by the U.S. Consumer Product Safety Commission (CPSC) on December 18, covers approximately 13,400 Blue Wave brand above-ground pools that are 48 inches deep or taller and utilize an exterior compression strap as part of the pool’s frame system.
Reason for the Recall
The affected pools feature a compression strap positioned around the outside of the vertical support poles. While the strap is designed to provide structural stability, the CPSC determined that its placement may unintentionally create a foothold.
According to the agency, this foothold could allow children to climb into the pool, even when the ladder has been removed, creating a risk of unsupervised access and potential drowning.
No injuries or fatalities have been reported in connection with the recalled products at the time of the announcement.
Affected Models
The recall applies to the following Blue Wave above-ground pool models:
• Blue Wave 15-Ft Rd 48-In Active Frame Pool
• Blue Wave 18-Ft Rd 52-In Active Frame Pool
• Blue Wave 18-Ft Rd 52-In Dark Cocoa Wicker Frame Pool
• Blue Wave 24-Ft Rd 52-In Dark Cocoa Wicker Frame Pool
• Blue Wave Rustic Cedar 15-Ft Round 48-In Deep Frame Swimming Pool Package W/Cover
• Blue Wave Rustic Cedar 18-Ft Round 52-In Deep Frame Swimming Pool Package W/Cover
• Blue Wave 18-Ft Round 52-In Gray Rattan Swimming Pool Package W/Cover
• Blue Wave 18-Ft Round 52-In Espresso Wicker Swimming Pool Package W/Cover
• Blue Wave 15-Ft Round 48-In Navy Blue Frame Swimming Pool Package W/Cover
• Blue Wave 18-Ft Round 52-In Navy Blue Frame Swimming Pool Package W/Cover
• Blue Wave 15-Ft Round 48-In Aspen Swimming Pool Package W/Cover
• Blue Wave Mocha Wicker 18-Ft Round 52-In Deep Swimming Pool Package With Cover
• Blue Wave Mocha Wicker 24-Ft Round 52-In Deep Swimming Pool Package With Cover
• Blue Wave Laguna 15-Ft Round 48-In Deep Swimming Pool Package With Cover
• Blue Wave Laguna 18-Ft Round 52-In Deep Swimming Pool Package With Cover
All affected models share a common design feature: an exterior compression strap that encircles the pool’s vertical supports.
Sales Channels and Distribution
The recalled pools were sold nationwide from January 2021 through July 2025 through a mix of big-box retailers, sporting goods stores, and online marketplaces, including:
• The Home Depot
• Lowe’s
• Dunham’s Sports
• Amazon
• Walmart
• Wayfair
Retailers have been notified to halt sales of affected models and to direct customers to the manufacturer’s recall remedy.
What Dealers and Retailers Should Know
For dealers and retail partners, the recall highlights the importance of prompt inventory review and customer outreach. Any remaining unsold stock matching the recalled models should be removed from the sales floor and distribution channels immediately.
Retailers that sold affected units during the recall period may see an increase in customer inquiries regarding eligibility, repair kits, and interim safety measures. Clear communication at the point of contact will be critical, particularly around the distinction between structural components and ladders, which many consumers assume are the primary access risk.
Service professionals and retail staff should also be prepared to explain that the recall does not involve a full product replacement, but rather a manufacturer-provided modification designed to eliminate the foothold while maintaining frame integrity.
Manufacturer Remedy
Blue Wave is offering a free repair kit to affected pool owners. The kit replaces the exterior compression strap with a lower-profile system installed closer to ground level. Once the repair is completed, the original strap can be removed.
Until the repair is installed, the manufacturer and CPSC recommend that pool owners prevent unsupervised access to the pool area or drain the pool temporarily.
Dealers and service professionals should advise customers not to remove or cut the compression strap prior to installing the repair kit, as doing so could compromise the pool’s structural stability.
