•The accumulation of VFAs was affected by temperature significantly.•Low temperature accelerated membrane fouling process.•Proteins were the dominant EPSs causing membrane fouling at low temperature.•Granular active carbon can mitigate membrane fouling via protein absorption. The performance of a no...
