Anthracite Filter Media are filtration materials for turbidity and
SS removal. Since the specific gravity is lighter than that of
Filter Sand, it is much used in combination with Filter Sand in
dual-media filtration, to consist reverse grain layers after
backwashing. In addition, because of high content carbon of this
product, it has high resistance to various chemicals and high
physical strength so that it is widely used for city and industrial
water purification.
Â
1. High void percentage and much removal capacity of turbidity and SS.Â
　In the Single-medium filtration treated by Filter Sand only, small particles are placed at upper part of layer, called as Surface filtration that turbidity and SS are caught at surface layer part mainly, and it results in less removal capacity of turbidity and SS. By use of Anthracite Filter Media of which the specific gravity is lighter than that of Filter Sand and even bigger particles can be placed on the Filter Sand, it is possible to enlarge the removal capacity of turbidity and SS as ideal Dual-media filtration in combination with Filter Sand and it is widely used in many water works in Japan. Since Anthracite Filter Media, rich angular and complicated in form, have high void percentage and large specific area, Deep bed filtration which is effective not only at the surface but also to the depth can be realized and it is also used with single and deep layer.
From these features, the filtration will be effective by use of
Anthracite Filter Media as follows.
* Extending filter run length to lower washing water waste and
improve treated water collection.
* Possible to quicken filter run length to save space for
installation of equipment.
* Prevention of filtration blockage due to Synedra, Microcystin,
etc.
* Prevention of mad ball forming at the surface of sand
layer.
Â
2. Micro-flocs growing easily.Â
　Since the grain has complicated form
and angularities, suspended solids are retained in the inter
granular spaces throughout the greater part of layer depth. After
addition of coagulant, the water to be treated which has been sent
out the filter without agitation is agitated and generates
micro-flocs while it passes through the inter granular space. It
results in improvement of treated water quality.
* Improvement of treated water quality.
Â
3. Easy change from single-medium filtration (by use of Filter Sand) to dual-media filtration.Â
　The washing method of Anthracite
Filter Media is the same as that of Filter Sand. It is no need to
install new washing equipment additionally in case of changing the
existing filter from single-medium filtration by only use of Filter
Sand to dual-media filtration by use of Anthracite Filter Media. It
is possible to improve the filtration effect by removing a part of
Filter Sand and fill up with Anthracite Filter Media
there.
* Improvement of filtration effect with reasonable
budget.
Â
4. High resistance to chemicalsÂ
　Since Anthracite Filter Media of good
quality contains less impurities and much carbon and it is not
dissolved in acidic and alkaline water, it is suitable as filter
medium and also used in the chemical industry for the filtration of
brine in soda manufacturers.
* Possible to use with various chemicals.
Â
5. Being used as a carrier for bio film treatment.Â
　Since Anthracite Filter Media have
high void percentage and large specific area, bio film is easily
formed on them. The medium is the most suitable not only for
physical filtration but also as a carrier for bio film
treatment.
* High effect as a carrier for bio film treatment
