SpAOP is here. The future of ultimate spa water

Redefining pristine, healthier spa water
Blue Lagoon, the internationally trusted name in UV-C water treatment, proudly introduces SpAOP, our latest innovation for spa and hot tub owners who value clean, safe, and healthy water. Designed for spa owners, professional installers, and forward-thinking Spa producers, SpAOP provides the newest solution to water disinfection, eliminating the harmful effects of traditional Ozone and Chlorine treatments. Are you looking for top quality water treatment with maximum efficiency? A solution that is eco-friendly and gets rid of the typical "pool smell" and irritation?
You've found it.

Clean spa water without the harmful effects of ozone and chemicals

Maintaining clean, fresh spa water over time can be a challenge. Standard treatments, like Ozone or high amounts of Chlorine, come with unwanted side effects. Ozone treatments in particular are increasingly restricted due to their harmful impacts on health and the environment, while Chlorine is notorious for its byproducts resulting in strong smell and potential to cause skin and eye irritation. Ready to say goodbye to red eyes, harmful odors, and hello to a cleaner, greener spa experience?

Advanced water quality without the compromise

More Than Just a Replacement
SpAOP delivers beyond conventional systems and combination setups. With our new SpAOP units, you no longer have to compromise between clean water and a healthy, relaxing spa experience. Unlike traditional systems that rely on harsh chemicals or ozonators—now banned in many regions—SpAOP offers an eco-friendly alternative that is safe for you and the environment.
The 185 nm UV-C light triggers an oxidation process that goes beyond the limitations of ozone. By forming highly reactive hydroxyl radicals, the SpAOP system delivers superior disinfection and oxidation without producing harmful by-products like ozone. This can reduce chlorine use by up to 80% and maintaining safe, pleasant water without the overwhelming chemical smell or irritation.

What is AOP exactly?
SpAOP isn’t just a replacement, it’s an upgrade to a higher standard of water care. AOP, or Advanced Oxidation Process, is a combination of UV-C light and oxidation technologies that create hydroxyl radicals. These radicals break down bacteria, viruses, and other harmful microorganisms as well as other organic and inorganic contaminations. This process is fast and highly efficient, making it perfect for spas and hot tubs. Our direct AOP does not need ozone to create radicals, so we bypass any negative by-products found with traditional solutions altogether.
