Water ManagementKorea Circuit cares for nature and humanity.

Thoroughly managing the sources of pollution to minimize the amount of environmental pollutants generated in the manufacturing process, and improving the process to remove the sources of pollution.
In addition, we use physical and chemical treatment methods for max 12,000 tons of waste water and try to minimize the amount of environmental pollutants, with the aim of becoming a leader in environmental preservation.
