- Abstract
In large‐scale processes displacement washing is a suitable method for the purification of a filter cake. Through pre‐dewatering prior to the wash step undesirable mixing of suspension and wash liquid is prevented. The effect of the undersaturated cake on the washing process is investigated in a laboratory nutsch filter. Dewatering kinetics before the wash step and rewetting kinetics at the beginning of the wash step show that rewetting is significantly faster. The initial saturation of S = 1 is no longer reached. Instead an equilibrium saturation S < 1 appears. The pre‐dewatering step shows no negative effect on the three areas of the washing process. However, it increases the process time.
