naturally mined ore, Pyrolox® is a mineral form of
manganese dioxide which has been used in water treatment
for more than 75 years. Pyrolox is a granular filtration
media for hydrogen sulfide, iron and manganese reduction.
Pyrolox functions as a catalyst, but itself remains relatively
works on a principle whereby the hydrogen sulfide, iron
and manganese are oxidized and trapped on the media while
simple backwashing cleans the bed. No chemical regeneration
is required, nothing is imparted into the drinking water
and Pyrolox has a high capacity for low contaminant concentrations.
can be used in conjunction with aeration, chlorination,
other pretreatment methods for difficult applications.
Chlorine or other oxidants accelerate the catalytic reaction.
of its heavy weight, it is very important that Pyrolox
filters are backwashed properly to insure adequate bed
expansion and continued service life.
Effective reduction of iron, sulfur and manganese
Durable material with long service life and low annual
attrition of bed
No chemical regeneration required, only periodic backwashing
Bed depth: application dependent
Backwash flow rate: 25-30 gpm per sq. ft.
Backwash expansion: 15-30% of bed depth
Service flow rate: 5 gpm/ sq. ft.
Freeboard: 40% of bed depth (min.)
