"Anthracite" - the filter medium received on special technology from anthracite of the Donetsk basin. It is a product of a production cycle of enrichment of anthracite with the special morphological structure giving when crushing receiving inert, wearproof material with the developed specific surface, big intergrain porosity and high abrasive stability. Appearance - a crumb of black and asphalt color with metal gloss and grains of a form, cubic or close to it.

Important indicators for the anthracite used as raw materials for production of our filter medium are:
- the regulated ash content (to 4% )
- extremely low sulfur content (no more than 1% )
- high mechanical strength (abradability of 0,3% , izmelchayemost of 2,8% )

According to specifications the fractional structure of a filter medium "Anthracite" is characterized by the following diameter of grains:

Granularity of I 0,6 - 1,6

Granularity of II 0,8 - 2,0

Granularity of III 1,0 - 3,0

Granularity of IV 2,0 - 4,0

Granularity of V 3,0 - 6,0

Granularity of VI 4,0 - 6,0

At the request of the consumer production of other sizes of fractions is possible.

"Anthracite" is successfully applied:
for water purification in system of chemical water treatment of combined heat and power plant, state district power station, the NPP, industrial enterprises;
as the supporting layer under ion exchange resins for improvement of quality of water;
for mechanical cleaning of water in system of water utilities, for increase in indicators of contaminant capacity of cleaning;
for purification of waste industrial waters, sewer waters after biological filters, etc.

It is used in open and pressure - type filters, contact clarifiers; application is also possible both at single - layer, and at multilayer loading of mechanical filters.

Application "Anthracite" in filters with two - layer loading in combination with quartz sand allows to achieve the following results:
high speed of filtering of water and improvement of quality of a filtrate at the exit
higher degree of contaminant capacity of loading (in comparison with single - layer sandy)
decrease in the entered doses of a coagulant and flocculant by 25 - 30%
reduction finally not only amounts of rinsing waters, but also reduction of time of back - flushing of the filter for 30 - 40%
