Pyrolox Fleck 5600 Iron Manganese Sulfur Water Filter 1.5 CU FT OF MEDIA TANK SIZE 10" X 54
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.
Pyrolox™ is a highly effective media for the removal of iron, manganese and hydrogen sulfide. This robust product has proven highly successful in both point-of-entry, municipal and point-of-use applications. Though each treatment application is unique, there are certain general guidelines that need to be followed in order to realize the full benefits of Pyrolox™ as a permanent media.
As with any media, frequent and thorough back-washing is essential for long-term success with Pyrolox™. The specific frequency of regular back-washing is dependent on water quality and application rate. A daily backwash at the appropriate rate is required to remove precipitated contaminants from the filter bed.
- Suggested back-wash rate: 25-30 gpm/sq. ft.
To maintain and further augment the long-term performance and removal capacity of the media, an oxidant feed of some type is strongly recommended. This will maintain the media and enhance removal capacity. Chlorine injection (options include chlorine, sodium hypochlorite, or calcium hypochlorite) immediately up stream of the filter feed is a simple way to meet this requirement. Other acceptable oxidants include air injection (oxygen is an oxidant), potassium permanganate, sodium permanganate, etc. Hydrogen peroxide is specifically prohibited for use as an oxidant.
Conditions for Operation
- pH: 6.5-9.0
- Bed Depth: Suggested depth 18 inches. Dependent on application and water quality.
- Underbed: Garnet #8, #8-#12. #3 Silica. Other materials are also suitable but must keep media from migrating downward and be heavy enough to remain in place during backwash.
- Freeboard: 40% of bed depth (min.)
- Service flow rate: 5 gpm/sq. ft.
Q. 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.
Q. 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.
Q. How does Pyrolox™ differ from greensand and Birm®?
Pyrolox™ is a pure granular form of manganese dioxide whereas greensand and Birm® are other minerals coated with manganese dioxide. This gives Pyrolox™ the ability to withstand regular backwashing and also provides a much greater oxidation capability than greensand or Birm®.
Q. Do I need to underbed Pyrolox™?
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.
