DEL Ozone introduces the first compact high-tech AOP system for residential pools. Advanced oxidation, through the production of hydroxyl free radicals (OH), one of the most powerful oxidisers available.
AOP, or Advanced Oxidation Process
The defining characteristic of an AOP system is the production of hydroxyl free radicals, a very powerful oxidant for disinfecting water.
The AOP system has been evolving since the 1980s, primarily for use in effective tertiary wastewater treatment. In the case of disinfection of residential swimming pool water, the chemical reaction produced is identical. In both applications, the water is disinfected more effectively than with ozone or UV alone.
In fact, AOP combines a variety of chemical treatments that can sanitize and disinfect water by oxidizing organic and non-organic contaminants.
In this case, Solar Eclipse uses DEL’s plasma ozone technology (patent pending), combined with high output low-pressure germicidal UV lamps to create a powerful yet cost-effective AOP system that is compact enough for residential pools.
With this system, all organic contaminants potentially present in the water of a residential pool are oxidized: microorganisms, human waste, hazardous chemicals such as pharmaceutical waste and petrochemicals, fungi, algae, pesticides and other toxic elements.
With a combination of these two methods, dependence on chlorine is reduced, microorganisms are deactivated or destroyed, and chloramines are broken down. The oxidation process occurs almost instantaneously upon contact with the contaminants.
Non-organic materials, such as dissolved metals (iron, manganese, etc.) found in potable water, are also oxidised, enabling their removal by filtration.
This advanced and innovative sanitizing system is synergistic (making it more effective) thus creating a higher disinfection potential for swimming pool water.
The by-products of AOP systems are clean enough for reuse, and environmentally safe, asserts the manufacturer.
Disinfection phases of the Solar Eclipse
1. The Ozone (via the ozone generator Advanced Plasma Gap - APG) directly oxidises contaminants when it is injected into the return line. However, a portion of the ozone is still available when it enters the UV chamber.
2. Germicidal UV continues the disinfection process by disrupting organic molecule DNA/RNA, but it also interacts with the remaining ozone to produce hydroxyl free radicals.
3. The hydroxyl free radicals complete the oxidation process. This powerful oxidant is extremely short-lived, but it instantly oxidizes the contaminants in pool water.
The components of the system
The Solar Eclipse residential pool sanitizer consists mainly of two components, the ozone generator and the UV lamp chamber, with pre-installed plumbing and wiring. The system is installed easily requiring only the water inlet and outlet connectors and an electrical connection.
â— The APG ozone generator provides a supply of ozone that remains almost constant over time. It has a robust and compact design with low power consumption (using about the same amount of energy as a 100-watt bulb).
â— Two low-pressure high output UV germicidal lamps are installed downstream from the ozone system on the return line. These carefully calibrated lamps emit light into a radiation chamber in the 254-nanometer wavelength, sometimes referred to as ultraviolet C shortwave.
Oxidation reaction occurs in the return line. The clean and disinfected water then flows back into the pool.
Basic installation protocols for pools
Solar Eclipse requires no substantial changes in the design or construction of swimming pools and the system is compatible with variable speed pumps. The same calibrated spring-driven check valve in DEL's popular standard manifold automatically adjusts to large variations in water flow / pressure.
