About Advanced Oxidation Process

This innovative sanitation solution is a significant improvement over all previous approaches to residential pool sanitation, yet it is fully compatible with standard existing residential pool power and plumbing mehods.The defining characteristic of AOP systems is the production of hydroxyl free radicals (•OH), the most powerful oxidizer available to safely disinfect residential pool water.


How it Works

Advanced Oxidation Process refers to a variety of chemical treatments that can sanitize and disinfect water by oxidizing organic and inorganic contaminants. The concept is similar to the use of ozone for disinfection, but AOPs go beyond standard treatment methods since they produce hydroxyl free radicals. Hydroxyl free radicals have a higher oxidation potential than any other substance, with the exception of elemental fluorine, which is not safe for direct human applications. 

In AOP systems, the highly unstable hydroxyl free radicals react with dissolved waterborne contaminants in a series of strong oxidation reactions. This process happens almost instantaneously. AOP systems are synergistic in the sense that they multiply the power of the precursor oxidants (like ozone) to yield more disinfection potential than the sum of the input taken separately.

The DEL Approach: Ozone + UV Light = AOP

DEL's AOP systems utilize DEL’s  proprietary Plasma Gap Ozone Technology combined with high output, low-pressure germicidal UV lamps to make a potent yet economical AOP system small enough for residential pools.

Benefits of AOP

There are two main reasons AOP systems are so desirable:

  • AOP is Highly Effective: AOP processes can fully oxidize organic contaminants of ALL kinds, including microorganisms, human waste, dangerous chemicals like pharmaceutical waste and petrochemicals, fungus, algae, pesticides and other toxic elements. They also oxidize non-organic materials, such as dissolved metals (iron, manganese, etc.) found in potable water, enabling their removal by filtration.


  • AOP is Environmentally Benign: The byproducts of AOP systems are clean enough for re-use. Even beginning with sewage waste, which is infinitely more contaminated than swimming pool water, these systems can eventually result in water pure enough to recycle. Byproducts may include water and carbon dioxide.
