Filter-Ox™
Resins, Media & Chemicals
Filter-Ox™
Filter-Ox™ is a highly effective filter media capable of reducing iron,
manganese and hydrogen sulfide from water through oxidation and
filtration. Soluble iron and manganese are oxidized and precipitated
by contact with the catalytic coating on the Filter-Ox™ granules.
The hydrogen sulfide is oxidized to an insoluble sulfur precipitate.
Precipitates are then filtered and removed by backwashing.
Filter-Ox™ is an engineered media that utilizes a super high purity
manganese dioxide coating bonded to a durable, lightweight silica
substrate. Manganese dioxide is a powerful oxidizer and Filter-Ox™
contains more manganese dioxide than other manganese based
filter medias. Manufactured in the USA, Filter-Ox™ contains almost
no fines and does not require long initial backwash times. A standard
sterilization treatment using chlorine is all that is needed at start up.
Untreated water should periodically be monitored for raw water
parameters. Treated water should periodically be monitored for
manganese, iron and hydrogen sulfide shortly before a regeneration
and immediately after a regeneration to monitor how the filter
system is functioning. Elevated treated water concentrations before
regeneration may mean that the filter media reduction capacity has
been exceeded. Take corrective actions as necessary.
Low pH or high pH are the most likely conditions leading to
media destruction.
Advantages
• Iron reduction over wide pH range
• Effective reduction of hydrogen sulfide in addition
to iron and/or manganese
• No harmful effects from a chlorine feed
• Low attrition for long bed life
