AFF111 Cake and Depth Filtration Teaching Equipment Educational Fluids Engineering Training Equipment Description With the processes in depth filtration and cake filtration can be observed and investigated. The suspension (water and diatomite as the solid) flows from the hopper into the top of the filter element, where the solids are separated off. The filtrate flows through a flow meter into the drain. The filter element has a porous filter medium at the bottom.
In cake filtration, the filter medium provides the foundation for buildup of the filter cake. In depth filtration, the filter medium supports the bulk solids (filter medium layer; gravel). Twin tube manometers measure the pressure loss over the filter element.
