Pyrolox Iron Removal Filters Information

What is Pyrolox and what is it used for?

Pyrolox is a granular water filtration media used for the removal of hydrogen sulfide, iron and manganese. Through a natural chemical reaction, Pyrolox has the ability to help you produce clean, high-quality water. Pyrolox works because of a catalyst reaction whereby hydrogen sulfide, iron, and manganese are oxidized on the media. Daily backwashing then flushes trapped particulate from the filter bed. Pyrolox is a natural mineral form of manganese dioxide, making it an environmentally sound means of water filtration.

What are the limits of removal by Pyrolox?

These are the limits:
pH 5-9 ( Best at pH higher than 6.5 )
Hydrogen sulfide 10 mg/l
Iron 10 mg/l
Manganese 8 mg/l

 Are there any impurities that are a problem for the operation of Pyrolox.

 Yes. Organic iron, sulfur, bacteria, tannins, chloride levels over 500 mg/l are all either not removed or affect the efficiency of the Pyrolox filter.

What pH range is ideal for Pyrolox?

Pyrolox works best between a pH range of 5 to 9. Ideal pH is between 6.5 and 7.

What is the life expectancy of Pyrolox?

The medium will last for an indefinite time. However, about 10-15% per year is lost due to attrition or lost fine media during backwash and should be replaced.

Why is a daily back-wash necessary when using Pyrolox?

Back-washing removes contaminants on the surface of the media allowing for better performance. Since Pyrolox™ turns sulfur, iron, and manganese into a particulate, the solids begin to coat the surface of the media, weakening its oxidation capacity. Thorough back-washing keeps the surface of the media free to continue the oxidation process.

Will Chlorine destroy the Pyrolox media?

No. Actually, using chlorine or other oxidants is strongly recommended as they will extend the life of the media.

Do Pyrolox filters require a gravel underbedding?

Yes. Without and underbed you will find the filter can have a poor backwash distribution. It is important to use an underbed that is heavier than Pyrolox™ to prevent migration into the media.
