Recycling Water Resource:
Effective use of water through our Closed Circulation Water System

   In UMCJ, as regard to the effective use of water resources considerations, no draining water discharge from our factory and reducing the burden to the environment as well as protecting the water resources are undergoing.

   For the above purposes, UMCJ is not only using the De-ionized water, which is made through ion exchange and filter treatment of well water and city supplied water, to wash semiconductors, but also able to control the usage of well water and city supplied water to the minimum level because that the used water discharged from our plant is reused by the Ultra Pure Water Production System through withdrawing treatment.

   Further more, the used water from kitchen and toilet is recycled for toilet use after purifying treatment.
