When used downstream of oxidizers, Pyrolox Advantage ™ effectively reduces iron, manganese, hydrogen sulfide and arsenic from ground water. It is an engineered filter media that provides superior performance compared to other manganese dioxide coated medias.
Understanding Oxidation & Filtration
Oxidation & Filtration is used to remove or reduce the following contaminants:
- Iron Fe+++
- Hydrogen Sulfide
The most common oxidizers are:
- Ozone O3
- Hydrogen Peroxide (<7%)
In the past Potassium Permanganate was also used and it worked well but could turn the water purple if not applied correctly.
How it Works
- The oxidizer chemical (chlorine, hydrogen peroxide) causes the contaminant to come out of solution so it can be filtered. For example – ferrous iron Fe++ comes out of solution and turns into Ferric iron Fe+++, which is now solid and visible to the eye as Ferric Hydroxide Fe(OH)3 and can be filtered.
- When the contaminant is oxidized the water passes through a filter which further reduces the contaminant to an acceptable level.
- Soluble iron, manganese and hydrogen sulfide are oxidized upon contact with manganese dioxide. The oxidation process causes these contaminants to come out of solution as a precipitate (solid) which can then be filtered.
- Filtration medias such as Pyrolox Advantage need to be re-fueled by an oxidizing chemical on an ongoing basis.
- Pyrolox Advantage is manufactured with metallurgical grade manganese dioxide. This results in longer run times between regenerations effectively reducing the cost of operation.
- Pure manganese-dioxide ores are too heavy and are difficult to backwash with residential well pumps.

- 🚫 Use hydrogen peroxide 7% or less otherwise it may rapidly degrades the media coating.
How it works
Soluble iron, manganese and hydrogen sulfide are oxidized upon contact with manganese dioxide. The oxidation process causes these contaminants to come out of solution as a precipitate (solid) which can then be filtered. Pyrolox Advantage has more manganese dioxide than competing products. This results in longer run times between regenerations effectively reducing the cost of operation.
*Continuous Regeneration with air is also effective. Please contact Urbans Aqua for details.
