In the wafer back polishing process and dicing process. It is processed with water deionized water. During the cooling and washing phase ( removal of polished powder ) large quantities of waste water is mixed as the polished powder is discharged. We use a ceramic filter (precision filter equipment made from fine ceramic ) and filter by reusing filtered clean water, constitute the closed system of eco-friendly for the earth.
We process waste water without discharging the disposed waste water into the rivers and so on.
Strong points of the eco-friendly earth ceramic filter are:
- Strong and long life: clogged filter can be used repeatedly over along period (more than 10 years by recycling disposal )
- High recalled rate: 99.9% of process waste water can be recalled and reused.
- Disposal without emitting chemicals: It doesn’t need any chemicals such as coagulant because it is filtered by a precision filter membrane made of fine ceramic controlled particle size advanced.
