Filter-Ox Water Treatment Media, 0.5 Cubic Foot Box

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 and the Filter-Ox granules. The hydrogen sulfide is oxidized to an insoluble sulfur precipitate. Precipitates are then filters and removed by back washing.

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 to 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. Low pH or high pH are the most likely conditions leading to media destruction.


Methods of Regeneration and Regeneration Requirements
- Continuous regeneration using chlorine feed or air are recommended
- Mg/l Cl21 (1x mg/l Fe) = (3x mg/l Mn)
- Air draw or air injection
- Use an injector that is two sizes larger than a typical softener application
- Draw/slow rinse time greater than 50 minutes
- Down flow rinse (fast rinse) 4 minutes minimum

Catalytic Oxidation (Co)
- Catalytic Oxidation 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 string oxidant directly to the raw water before the Filter-Ox Filter. Chlorine should be fed at least 10-20 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

Advantages:
- Iron reduction over a 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
