How the Oxidizer Plus+ Works:
1. How are we getting rid of the smell?
2. Why are we reducing staining? H2S + 2 O2 > H2SO4 (lowers pH)

Elimination of "Smelly Water"
"Smelly rotten egg" water is created when hydrogen sulfide gas is formed in water. Hydrogen sulfide is soluble up to 437 cm3/100cc of 32 degrees F cold water and decreases it's solubility to 186 cm3/104 degrees F hot water. As the water warms up the hydrogen sulfide is released into the air above the water with a characteristic "rotten egg" smell.
The Oxidizer Plus+ aerates and oxygenates "smelly water" by spraying water through a compressed bubble of air in an enclosed tank. The spray increases water's surface area and enhances dissolving of air (and oxygen). The increased surface area provides a medium to enhanced oxygenation of hydrogen sulfide to sulfuric acid. These compounds acidify water and lower the pH.
The water is collected at the bottom of the tank and drawn off by a bottom feeding tube and exits the unit.

Reduction of Staining of Fixtures:
Sulfuric acid from above drives the reduction of fixture staining.
Ferrous oxide (FeO), ferric oxide (Fe2O3) and ferric oxide hydrate (Fe2O3x H2O) are present in hard water. Ferrous oxide is typically black. Ferric oxide is typically red-brown to black. Ferric oxide hydrate is typically a red-brown amorphous powder or gel. All three compounds are insoluble in cold and hot water.
All three chemicals will stain porcelain fixtures. All the chemicals are soluble in acids. Ferric oxide is notably soluble in sulfuric acid. The lowered pH (from sulfuric acid formation) increases the solubility of these three chemicals and provides a "clearer" solution which reduces water stain.
