文摘
- •
Alginate gel fouling and cleaning mechanisms are visualized in RO and FO.
- •
Methylene blue stains low-salinity gel without affecting fouling or cleaning.
- •
When cleaning with high feed velocity, gel peels off in macroscopic pieces.
- •
Changing solution ionic composition causes gel to swell, wrinkle and detach.
- •
Images provide evidence of vapor formation inside FO membrane in PRO orientation.
