Alpine Pure Pyrolox Benefits:
Remove iron, sulfur, and manganese with one filter!
A 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 unchanged.
Pyrolox 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.
Pyrolox can be used in conjunction with
aeration, chlorination, ozone or other
pretreatment methods for difficult
applications. Chlorine or other oxidants
accelerate the catalytic reaction.
Because of its heavy weight, it is very
important that Pyrolox filters are
backwashed properly to insure adequate
bed expansion and continued service
