Hydro fluoric Acid Recycling System
|
|
|
No wastes are discharged into the river by Yashiro Plant
The Yashiro Plant, at which produces semiconductors, introduced a hydrofluoric
acid recycling system. This is the first system in the world that recovers hydrofluoric acid
by using a crystallization method to turn the acid into fluorite, which can be reused to make
hydrofluoric acid again. This system requires less space than the existing macro-molecule coagulant
system and enables the generation of artificial hydrofluoric acid of at least 90% purity that can
be recycled as chemical ingredients.
Hydrofluoric acid is a chemical substance used in the
etching process in semiconductor manufacturing. In the past, this substance was properly processed
as sludge, but the introduction of the acid recycling system resulted in zero waste at a higher
level by circulating the substance for recycling. This system contributed to modifications in
the existing wastewater processing device, resulting in significant energy conservation. The
New Energy and Industrial Technology Development Organization " NEDO " approved
a subsidy of this technology because of its innovation and energy conserving capability.
In 2004, the advanced fluorine adsorption system was installed after the process of the hydrofluoric
acid recycling system to further reduce the concentration of fluorine in the drain water. The water
processed by the advanced system is returned to the previous recycle system to recover fluorine,
which contributes to recycle resources.
