文摘
- •
TFC FO membrane is more vulnerable to scaling than CTA FO membrane
- •
Spacer promotes crystal formation between its filament and membrane surface
- •
Crystal growth in AL-FS between membrane and spacer may damage rejection layer
- •
Severe internal scaling in AL-DS results in remarkable flux drop
- •
Antiscalant can effectively prevent scaling in AL-FS, but had little effect in AL-DS
