Vertical stacking of the horizontal automatic filter press chambers allows for maximum use of your plant space and leads to improved cake washing efficiency. Horizontal positioning of the filter cakes ensures uniformity, constant thickness, homogeneous structure and equal flow resistance.

A REVIEW OF FILTER PRESS BASICS AND ISSUES VERSUS

2021-3-29  Filter press operators frequently claim “extremely well washed” filter cakes, often giving the impression that no other filter would be an equal to this. In some special cases this can be true, but in general, whereas the washing can be good, it is rarely very efficient, in terms of time cycle nor usage of the wash

Filter cake blow drying for filter presses MSE
