文摘
- •
Operating temperatures strongly influenced water flux and membrane scaling.
- •
It was more difficulty to clean membranes scaled at a high temperature.
- •
Stable operation at 70% water recovery was achieved using anti-scalant at 0.5 mg/L.
- •
Vinegar could be used to restore the membrane water flux.
- •
Repetitive vinegar cleaning led to gradual performance deterioration.
