Description
A specialized membrane for waste acid recovery without electrical drive, with an acid recovery rate of 80%–90% and metal rejection >95%.
Detailed description
Thickness: 90–120μm; Membrane resistance: 0.8–1.3Ω・cm²; Ion exchange capacity: 1.5–2.3 meq/g. DD membranes are compatible with hydrochloric acid/sulfuric acid, PD membranes exclusively recover phosphoric acid domestically, and MD membranes are suitable for complex mixed acids. No electricity required—driven solely by concentration differences.
Application scenarios
Anodizing of aluminum profiles, titanium dioxide production, stainless steel pickling, etching foil processing, phosphoric acid recovery, and waste acid resource utilization.
