文摘
- •
An axial vibration membrane (AVM) was designed to control membrane fouling.
- •
Enhancing shear rate can improve critical flux and reduce membrane fouling.
- •
XDLVO theory explained why membrane was more easily fouled at low shear rate.
- •
Interaction force expounded how AVM controlled algae adhering to membrane.
- •
The mechanism of AVM controlling membrane fouling was presented.
