Closed system for surface treatment washing water

Japan/Hasama Ricoh

Ricoh designs and manufactures precision press parts and dies and recycles waste liquids from washing processes. We traditionally disposed all water from washing painted and precision press parts. In 1998, we adopted a closed system for all of these liquids, purifying wastewater through ion exchange treatment for reuse in washing. This setup has reduced our annual tap water consumption by around 60,000 cubic meters, cutting water bills and wastewater treatment costs.
