|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. 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.
|CATALYTIC OXIDATION (CO)
Catalytic Oxidation (CO) operation is recommended in applications where iron removal is the main objective in well waters with or without the presence of manganese. This method involves the feeding of a predetermined amount of chlorine (Cl2) or other strong oxidant directly to the raw water before the Filter-Ox filter. Chlorine should be fed at least 10 to 20 seconds upstream of the filter, or as far upstream of the filter as possible to insure adequate contact time. A free chlorine residual carried through the filter will maintain Filter-Ox.
NOTES ON USING FILTER-OX
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.
