 Factors affecting fouling :-

• Membrane properties: pore size, hydrophobicity, pore size distribution and membrane material.

Solution properties: solid (particle) concentration, particle size and nature of components.

• Operating conditions: pH, temperature, flow rate and pressure.

Biological fouling, mineral fouling/Scaling. These are the main factors if not controlled by chemical dosing and proper pre-treatment of in-fluent (if required),  reduces the life of a membrane magnificently.

I would add to the first answer the scaling and its negative consequences which is the main cause of membrane deterioration
