Technology data

Name of technology	Water treatment with Carbon Fiber
Field of the technology	Major category: Prevention and destruction of pollution	Sub-category: Industrial waste water, Sewage, Land water, Ocean
Conceivable applications	Water treatment with Carbon Fiber named "Mira Carbon"; River purification, Lake/marsh purification (closed water bodies), Purification of seawater areas (Inland seas, closed sea water bodies). Ecosystem integrity; Seaweed bed formation
Performance	Water quality purification using carbon fiber is effective in improvement of transparency in a short time, decrease COD and BOD, and purification of TN and TP. Removal rate of water quality purification using carbon fiber items (％) Items River Lake Sewage Biological Oxygen Demand (BOD) 50 - 70 20 - 90 90 - 95 Suspended Solid (SS) 50 - 70 20 - 90 90 - 95 Total Nitrogen (TN) 10 - 30 10 - 30 30 - 70 Total Phosphorus (TP) 10 - 50 30 - 90 30 - 50 Chl-a   10 - 90
Technical maturity	Developed in 2000 Commercialized in 2008 Past performances Japan; more than 300 locations Other countries; more than 20 locations (China, Korea, Taiwan etc.)
Competitive advantage	Carbon fiber has large surface on which microorganisms can live. Microorganisms can naturally decompose contaminants and pollutants. The contaminants and pollutants are adsorbed without any power when carbon fiber is swayed by water current. Therefore carbon fiber maintains cost efficiency. Low installation cost, easy maintenance control, and no running costs. Ecosystem integrity and conservation biodiversity.
Conceivable risk	Outflow of carbon fiber by a natural disaster. Damage of carbon fiber by improper installation.
Information on patent related to this technology	Acquisition patents (Japan) JP 3331372, JP 3328700, JP 3080567, JP 2954509, JP P2009-195848A, JP P2009-195849A, JP P2009-195850A

Schematic illustration of the technology

"MiraCarbon" is the carbon fiber of water quality purification. It has the light and strong industrial characteristic and the large surface, therefore pollutants are adsorbed and microorganisms are fixed and activated. Then pollution gets gone and it makes the water clean.

Example of Application

• Water purification for river, lake and marsh which a blue green algae occurrence caused by eutrophication.
• Biodiversity conservatory in river, lake and marsh.
• Water purification in coast sea area and reduce the development of red tide.
• Pretreatment facilities such as seawater desalination plants.
• Improvement in functional of the wastewater treatment facilities which need the high processing effect by wastewater toughening of regulations or load increase.
• Help to grow seaweed and promote to absorb CO2 with photosynthesis.
