Reuse and recycling business: separation and recovery of mixed acids.

We are effectively utilizing resources with technology certified as successful by the Japan Science and Technology Agency.

We would like to introduce our company's "separation and recovery of mixed acids." Etching processes using mixed acids are widely used in the manufacturing of liquid crystals and semiconductors, and at the same time, used mixed acid wastewater has been generated. Traditionally, a portion of this mixed acid wastewater has been used for pickling in steel mills; however, the majority has not been effectively utilized, as it has been neutralized with large amounts of alkali and then incinerated. In response, our company established a technology to separate mixed acid wastewater and recover it as a single acid, in collaboration with Kansai University. The recovered acid can now be effectively utilized as a resource through reuse and recycling. [Features] - Established technology to separate mixed acid wastewater and recover it as a single acid - Recovered acid can be effectively utilized as a resource through reuse and recycling - Recognized as a "device for acid recovery from mixed acid wastewater using solvent extraction" by the Japan Science and Technology Agency *For more details, please refer to the PDF document or feel free to contact us.
