OZONEX™ 203 Ozone Generator Oxidizing System For Holding Tank

When Water Needs More Than Filtration Alone

Many well water problems begin before water reaches the filter. Dissolved iron, manganese, hydrogen sulfide, and naturally occurring bacteria remain suspended in solution, making them difficult for conventional filtration systems to remove efficiently. Without proper oxidation, these contaminants can cause rotten egg odors, metallic taste, staining, slimy buildup, and reduced filtration performance throughout the home.

Ozone oxidation addresses these challenges before filtration begins. By converting dissolved contaminants into solid particles, ozone allows downstream filtration equipment to remove them more effectively while helping control nuisance bacteria that contribute to odors and biological fouling. The result is a cleaner, more efficient treatment process without relying on chlorine or chemical injection.

Where Does Oxidation Improve Water Quality?

• Rotten egg odors caused by hydrogen sulfide


• Orange, black, or brown staining from iron and manganese


• Metallic taste and unpleasant water odors


• Slimy iron bacteria and sulfur-reducing bacteria buildup


• Reduced filtration performance caused by dissolved contaminants

That's why the OZONEX™ 203 is engineered to introduce ozone directly into an atmospheric holding tank, allowing oxidation to occur before water reaches the filtration system.

Engineering Designed for Efficient Oxidation

The OZONEX™ 203 generates ozone on demand using electrical corona discharge technology, eliminating the need to store or handle chemical oxidizers. Ozone is introduced into the holding tank where it rapidly reacts with dissolved iron, manganese, hydrogen sulfide, and organic compounds. As oxidation occurs, contaminants become insoluble particles that can be captured by properly designed filtration systems.

This treatment process also helps control iron bacteria and sulfur-reducing bacteria that contribute to slime formation, unpleasant odors, and fouling of plumbing and filtration equipment. Because ozone naturally reverts back to oxygen after completing oxidation, the process leaves no chemical residual while supporting cleaner water throughout the treatment system.

Designed for continuous residential operation, the compact ozone generator integrates easily with atmospheric storage tanks and oxidation systems. Its chemical-free operation minimizes maintenance while reducing dependence on chlorine injection and other consumable treatment chemicals.

Pure Water Living

Water that smells fresh, looks clear, and protects plumbing creates a more comfortable home every day. Oxidizing contaminants before filtration helps reduce staining on sinks and fixtures, minimizes unpleasant odors during showers, and improves the overall performance of downstream water treatment equipment.

By helping filtration systems work more efficiently, the OZONEX™ 203 also supports longer filter media life, reduces maintenance, and contributes to more reliable whole-home water treatment. Families enjoy cleaner water while benefiting from a treatment process that relies on oxygen rather than chemical additives.

That's what happens when oxidation becomes the first step toward better water. Pure Water. Pure Trust.

Completing Your Water Strategy

The OZONEX™ 203 is designed to work as part of a complete well water treatment system. After ozone oxidation, properly selected filtration equipment removes the oxidized contaminants, delivering cleaner water throughout the home. Pairing ozone oxidation with iron filtration, activated carbon filtration, or whole-house treatment systems creates a comprehensive solution for challenging well water conditions.
