Conclusion
Progress towards:I understanding the mechanisms of filter cake formationI quantifying the impact of:
I particle sizeI crossflow velocityI lift forcesI ...
Future work:I improving behaviour of particles in the filter cakeI extending interaction between filter cake and liquid phaseI use the Segre-Silberberg effect to reduce membrane fouling?
