Pyrolox Advantage is the newer and synthetic version of Pyrolox. The granular media has received a 12.5% manganese dioxide coating. In the world of manganese dioxide filter media it can be considered as a light-weight product. The manganese dioxide acts as a catalyst to oxidize, precipitate and remove different contaminants: iron, manganese, hydrogen sulfide and in some specific cases arsenic. The media works at is best when it is continuously regenerated with chlorine, air, ozone or hydrogen peroxide.

Removal of Fe2+ and Mn2+
The most common application for this media; manganese minerals have a well-documented record of capability for removal of these species1. Pyrolox® Advantage removes soluble ions by the same mechanism as natural ore products, but faster and with better efficiency at low contaminant concentration. Results of our equilibrium and kinetic measurements are given in Appendices A and B.
Removal of As3+
Pyrolox® Advantage can be used to remove soluble arsenic indirectly by co-precipitation with Fe. This requires either the presence of Fe in the raw water or the addition of Fe ahead of the filter system. Pyrolox® Advantage has no inherent capacity to remove arsenic ions and should not be used non catalytically for the treatment of arsenic-contaminated raw water in the absence of soluble iron. Typical application requires Fe : As ratio of 30:1. Co-precipitation and removal is a function of bed contact, pH and ion concentration. For this reason, Prince recommends that filter designers pilot a small installation to confirm efficacy for specific situations. When treating water with > 10 ppb As it may be necessary to add a second polishing stage to the process.
