Case study
0.4 m³/h Automotive Paint-Shop Cleaning-Liquid Recovery Project
This project treats water-based solvent cleaning waste liquid from an automotive paint shop at a scale of 0.4 m³/h. It combines ultrafiltration and nanofiltration for cleaning-liquid reuse and volume reduction.
Project overview
This project treats water-based solvent cleaning waste liquid from an automotive paint shop at a scale of 0.4 m³/h. It combines ultrafiltration and nanofiltration for cleaning-liquid reuse and volume reduction.
Plum’s scope of supply
Plum supplied the treatment systems described for this project, including ultrafiltration to retain paint residues, nanofiltration separation, and cleaning-liquid recovery.
Process route
Water-based solvent cleaning waste liquid → ultrafiltration to retain paint residue → nanofiltration separation → cleaning-liquid reuse and volume reduction
Ultrafiltration retains paint residue, followed by nanofiltration separation as part of the cleaning-liquid recovery process.
