 Some of the highest quality
iron
filters use a media called Terminox. Terminox, a
naturally mined ore, is a mineral form of manganese dioxide which
has been used in water treatment for more than 75 years. Terminox is
a granular filtration media for hydrogen sulfide, iron and manganese
reduction. Terminox functions as a catalyst, but itself remains
relatively unchanged. Terminox 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 Terminox has a high capacity for low contaminant
concentrations. Terminox can be used in conjunction with aeration,
chlorination, ozone or other pretreatment methods for difficult
applications. Chlorine or other oxidants accelerate the catalytic
reaction
Terminox Advantages:
- 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
Terminox Physical Properties:
- Color: black
- Bulk Density: 125 lbs./cu. ft.
- Mesh Size: 8 x 20
- Effective Size: 0.51 mm
- Uniform Coefficient: 1.7
- Specific Gravity: 3.8
How does a filter work?
A filter has three different operations that it
performs. The head controls these functions and they are as follows:
Service - During service (filtration) the water is
directed down through the filter media where the particles in the
water are trapped. Once the water has reached the bottom of the
tank, it returns to the top of the tank through the distributor.
Backwash - The head will determine when the system
needs to be backwashed or regenerated based on elapsed time or water
usage. During backwash the head will direct water down through the
distributor and up through the media. This flow will be of enough
force to actually lift the media and shake lose any trapped
particles. The water that leaves the top of the tank is directed to
the drain.
Rinse - Once
the media has been backwashed, it is rinsed by again sending water
down through the media and then to drain. This will rinse any lose
material at the bottom of the bed and in the riser to drain. Once
rinsed, the filter will return to service.
