Other types of activated carbon

Anthracite
Anthracite filter media is has been manufactured to an appropriately sized particle diameter using anthracite. As a filter medium in the form of particles or powder, it is used for large-scale water treatment of water and
sewage. Carbon, the main component of anthracite, is suitable for use as a filter medium because it is more
resistant to corrosion of water and chemicals than other substances and has less contamination.
The long filtration duration saves maintenance costs and has a small specific gravity compared to sand, which makes it easy to separate suspended substances when backwashing. Shinkwang Anthracite is a specially
treated filtration medium and has a long filtration passageway with a large surface area and adsorption
properties, so it is possible to separate very small particles contained in a solution, that is, colloids or
suspended particles.

Classification		Quality
Product name	Size(㎜)
Small	1~2	Fixed carbon : 80% or more Ash : 10% or less Hardness : 90% or more Uniformity coefficient : 1.6 or less Bulk density : 0.7∼0.8 Hydrochloric acid solubility : 1.5% or less
Medium	2~3
Large	3~5

Use	Characteristics
Multi-layer filtering	The referse particle size distribution, efficiency increase, and backwash expansion rate are large.
Drinking water/ sewage filtering	Enhanced filtering capacity, economical facilities, small facility area
Adsorbed water(oil) filtering	Non-coagulability, easy backwashing and desorption
Corrosive solution filtering	Corrosion-resisting, insolubility, unresponsiveness
Boiler water filtering	"silica" eluate, metal erosion control, enhanced heat efficiency
Seawater, saltwater filtering	Non-coagulability, enhanced filtering efficiency

Spherical charcoal
It is ball-shaped activated carbon with no dust and maintains high hardness. It has little pressure loss, is easy
to remove SS when using water quality, and has stronger SS removal ability when backwashing.

Special activated carbon
Carbon fiber, activated carbon with an adjusted pore size, chemical revival activated carbon, honeycomb
activated carbon

Oak activated carbon
Oak activated carbon with enhanced charcoal characteristics and adsorption capacity.
By filtering dust or wastes in the air, the indoor air can be comfortably used for ventilation or humidification,
and the effect of adsorbing electromagnetic waves is good, so it is possible to reduce the electromagnetic
wave entering the human body. Since Oak activated carbon contains various negative ions, fatigue can be
easily relieved due to the negative ion effect, and it can also help you get a good night's sleep.

Reactivated carbon
By reusing the activated carbon that has been used, it can be recovered and reused as a new product.
