Anthracite

AnthraciteAnthracite is smokeless coal crushed into granules. We use Hongai coal produced in northern Vietnam for our products. Anthracite is lighter than filter sand and its porosity is higher than that of filter sand. Therefore, it is used for the upper layer of dual filtration or multilayer filtration to increase the filtering capacity. It can also be used for single layer filtration.
* We provide anthracite of varying particle size.

Characteristic
1)
We can make use of the properties of anthracite by using it in the upper layer of dual filtration. The filtration rate, the quality of filtered water and the filter run time are dramatically improved compared to those of single filtration by filter sand or porous filter media.
2)
Since anthracite captures a large amount of suspended substances, it can be used for single filtration for the purpose of coarse filtration of highly turbid water if an appropriate particle size is selected.
3)
Anthracite is appropriate to be used as filter media when dissolution of silica is not desired.
4)
Anthracite can be used for wide-ranging purposes, for example, for water supply, industrial water, sewage, industrial wastewater treatment, restoration of water for bathhouses or pools.
