- Pressure: 1-5 bar
2. Acid/Alkali Resistant Inorganic Membranes
- Application: Papermaking black liquor
- COD removal: 85-95%
- Lignin recovery: 90-98%
3. Membrane Types
- MF: 0.1-10 micron, 0.5-2 bar
- UF: 0.01-0.1 micron, 1-5 bar
- NF: 0.001-0.01 micron, 5-15 bar
- RO: 0.0001-0.001 micron, 15-80 bar
Ion Exchange Resin Method
1. Heavy Metal Recovery
- Target metals: Cu, Ni, Zn, Cr, Cd, Pb, Au, Ag, Pt
- Removal efficiency: 95-99.9%
- Resin cycles: 500-1000+
2. Toxic Substance Removal
- Cyanide, Fluoride, Nitrate, Perchlorate, Arsenic
Biodegradation Method
