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.

Backwashing
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.

Oxidant Feed
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.
