Filtration & cake washing
Designing a cake-washing trial
Cake washing should be judged by the impurity remaining in the recovered product, not by the amount of wash liquid added.

Filtration & cake washing
Evaluate cake formation, media, washing, crystal quality and repeated-cycle behaviour. Product purity and recovery belong beside moisture in the trial plan.

How viscosity and temperature change separation
Liquid viscosity influences how readily liquid drains through a cake and how particles move during sedimentation.

Compressible filter cakes: why more force may not mean faster filtration
A compressible cake changes its pore structure as the applied load increases.

Cake washing when the valuable product dissolves in the wash liquid
Cake washing can improve purity while reducing product recovery if valuable solids dissolve in the wash liquid.

Filter-cloth blinding: distinguish media blockage from cake resistance
Slower filtration over successive batches can arise from blocked media, a compacted residual heel or a change in the slurry.
