Effective size:
.60-2.30 millimeters
Anthracite typically produces consistent improvements
in turbidity removal because, in part, to more efficient
solids loading. Low uniformity coefficient media also
produces smaller changes in effluent turbidity during
periods of peak influent turbidity. Northern's
anthracite filter media is produced from the highest
quality anthracite available to ensure the physical
characteristics of hardness, durability and performance.

Birm is an efficient media to remove dissolved iron
and manganese compounds from raw water supplies. It
acts as an insoluble catalyst to enhance the reaction
between dissolved oxygen and the iron compounds.
Other advantages of birm include long material life
with relatively low attrition loss, a wide temperature
performance range and extremely high removal efficiency.
Under proper water conditions, no chemicals are required
for maintenance. Regeneration is not required.

Physical characteristics:
|
Color:
Light brown
Effective size:
.35 - 2.5 millimeters
Acid solubility:
<1.7%
Specific gravity:
2.67
MOH hardness: 7
Filter sand is an extremely effective filter media because
of its ability to hold back coagulum or precipitates
containing impurities. Filter sand size, angularity
and hardness are the important filter sand characteristics
to ensure proper filtering.
Our filter sand is triple washed in our manufacturing
process producing a squeaky clean filter sand that
is virtually silt and fines free. Initial backwash
cycles are reduced as well, saving significant amounts
of time and water in your start-up backwash cycle.

FILTER-AG® |
| Physical characteristics:
|
| Color: light
gray to near white
Density: 24 - 26 pounds per cubic foot
Effective size: .57 millimeters
UC (D 60): 1.66
Filter-AG granules have irregular surface characteristics
allowing maximum removal of suspended matter throughout
the filter bed. Filter-AG can be used in either pressure
or gravity flow filter systems. It typically removes
normal suspended dolids down to 20 – 40 micron ranges.
Advantages of Filter-AG include less pressure loss
than most other mediums. It is lightweight and requires
lower backwash rates. Filter-AG has high dirt removal
capacity that result in longer filter runs with substantial
savings in labor cost, backwash water and time out
service.

Almandite garnet is a chemically inert non-metallic
mineral that is quite common in the natural environment.
Garnet is well known for its hardness and durability.
It has a high specific gravity as well as its chemical

Effective size: .30 - .35 millimeters
UC (D 60): < 1.6
Manganese greensand is a purple-black filter medium
that is used for the removal of soluble iron, manganese
and hydrogen sulfide from well water supplies. It
also has the capacity to remove radium and arsenic.
It is produced from the mineral glauconite (zeolite).
Using iron exchange properties of natural zeolite,
a manganese dioxide coating is deposited on the surface
of the glauconite grains. The manganese dioxide acts
as a catalyst in the oxidation reduction reaction
of iron and manganese.
This media can be used in two methods of operation:
continuous regeneration (CR) or intermittent regeneration
(IR).
AWWA Standard B100-01 and NSF Standard 61 approved.

MTM is a granular
manganese dioxide filtering media used for reducing
iron, manganese and hydrogen sulfide from water. Its
active surface coating oxidizes and precipitates soluble
iron and manganese. Hydrogen sulfide is oxidized to
a sulfur. The precipitates are filtered out in the granular
bed and removed by backwashing.
