Pure water means generally, water that has drawn the resistance value to a certain level by passing through the ion exchange resin through a simple pre-treatment system or obtained from a distillation device.
Recently, however, ultra-pure water used by semiconductor, solar and pharmaceutical companies has been used with extremely removed organic matter, particulates and microbes, as well as metal ion.
In this way, it is possible to improve productivity as well as to be sophisticated LSI Patterns more.

In addition, R/O SYSTEM is used for pre-treatment processes and EDI, MBP, and U/F are used for post-treatment processes to reduce production costs due to the heavy use of ultra-pure water.
