What Is the Advanox System and How Does It Improve Pool Water Quality?

The Advanox system is an advanced oxidation water treatment process developed for swimming pools to improve water quality by reducing organic pollutants and combined chlorine (chloramines). It works by using powerful hydroxyl radicals (OH·), which are generated through a controlled oxidation reaction. These radicals break down organic substances in the water such as cosmetics, sweat, and other contaminants, helping to achieve cleaner and safer pool water. When used in combination with other Dryden Aqua technologies, the Advanox system contributes to lower chloramine levels, improved water clarity, and reduced formation of harmful by-products. This blog explains what the Advanox system is, how it works, and where it is used in modern pool treatment systems.

What does the Advanox system do in pools?

The Advanox system is designed to reduce organic substances and organic chloramines in swimming pool water. According to Dryden Aqua, it works as a state-of-the-art advanced oxidation process that helps eliminate contaminants that conventional disinfection alone cannot fully remove.

By targeting organic pollution, the Advanox system reduces the load on chlorine-based disinfectants. This helps improve overall water quality and supports lower levels of combined chlorine, which is often responsible for unpleasant odours and irritation in indoor pools. It is especially effective in maintaining stable and high-quality water conditions in heavily used swimming environments. 

How does the Advanox system work?

The Advanox system works through advanced oxidation, where hydrogen peroxide (H₂O₂) is split into hydroxyl radicals (OH·) using UV energy. These hydroxyl radicals are extremely powerful oxidising agents that react with and break down organic compounds in the water.

This process converts contaminants into harmless substances and helps prevent the buildup of pollutants that can affect water quality. Unlike some traditional oxidation methods, hydroxyl radicals do not form harmful disinfection by-products, making the process highly efficient for water treatment applications in pools. 

Why is the Advanox system used in indoor pools?

Indoor pools often experience higher levels of combined chlorine due to limited ventilation and increased swimmer load. The Advanox system is used to help reduce these chloramines by breaking down the organic compounds that contribute to their formation.

Dryden Aqua describes Advanox as part of a system designed to achieve very low combined chlorine levels when used in combination with complementary treatment technologies. This helps improve water quality and reduces the presence of irritating chloramine compounds in the pool environment. 

What pollutants does Advanox remove?

The Advanox system targets organic substances in water that contribute to poor pool quality. These include compounds introduced by swimmers such as cosmetics, body oils, and other organic residues.

Through advanced oxidation, these contaminants are broken down at a molecular level into simpler, harmless components. This helps improve overall water clarity and reduces the chemical demand placed on standard disinfection systems, supporting more stable and efficient water treatment. 

How does Advanox improve combined chlorine levels?

Combined chlorine (chloramines) is formed when chlorine reacts with organic matter in pool water. The Advanox system helps reduce the formation of these compounds by removing organic precursors before they can react with chlorine.

Dryden Aqua states that when used as part of an integrated system, Advanox helps achieve significantly lower combined chlorine concentrations, improving both water quality and swimmer comfort. This is particularly important in indoor pools where chloramine build-up can impact air quality. 

What systems is Advanox used with?

The Advanox system is often used as part of an integrated Dryden Aqua treatment approach. It is designed to work alongside other systems that target different aspects of pool water quality, helping to create a complete treatment solution.

In combination with complementary technologies, Advanox contributes to improved removal of both organic and inorganic chloramines and supports overall system efficiency. This integrated approach helps pool operators achieve more stable and sustainable water treatment outcomes. 

Conclusion: Why use the Advanox system?

The Advanox system is an advanced oxidation process designed to improve swimming pool water quality by breaking down organic pollutants and reducing chloramine formation. Using hydroxyl radicals generated through oxidation, it helps deliver cleaner, clearer, and more stable water conditions.

When integrated into a wider treatment system, the Advanox system supports improved water quality, reduced combined chlorine levels, and enhanced swimmer comfort. It is a key part of modern, high-performance pool water treatment strategies developed by Dryden Aqua.
