The Standard of tassel type is MiraCarbon CFK-3, CFS-2. |
| ※ |
Installation method depends on MiraCarbon tassel type qty. |
| ※ |
he length of MiraCarbon lattice type is determined by water depth as CFK-4
as standard. |
| ※ |
MiraCarbon lattice type is attached to installation equipment by installing
rope |

The characteristics of CarbonFIber contact media |
●Mass adhesion of activated sludge
The filament surface is uneven, so the absorbing amount on each surface
is large. The filaments are close to each other, and it can keep mass sludge
between filaments. Because sludge gets in deep inside of the clusters,
it makes longer residence time. Thus, it can prevent waste sludge.
●Treatment by microorganism activation
Anaerobic bacteria accumulate in the deep inside of the filament cluster.
Aerobic bacteria with high activation also accumulate around it by swaying
its filament and current of water. Microorganisms activate with swaying
filament, and then organic matters such as BOD ・CODare decomposed.MiraCarbon
facilitate decomposition and removal of nutrient salts such as nitrogen
and phosphorus.

Mechanism of water purification |
 
◆Application consideration
１．MiraCarbon has equal to or larger total specific surface area than advanced
activated carbon. However, as contact media, pores inside of filament are
not effective for sludge adhesion, so only outside surface area is included
to calculate.
２．Because textile CarbonFiber does not spread in the water, effective surface
area decreases.
３．Large amount of sludge are attached on the uneven filament surface and
between filament.
４．Please use lattice or textile type contact media in case of faster than
0.3 m/s flow or aeration since fiber might be cut down.
５．Please refer the dedicated site for MiraCarbon, installation set, and
unit.
