Features:
Cake and depth filtration with different suspensions and filter medium layers 

With Tesca Cake and depth Filtration Apparatus, the processes of 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 the build-up 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.
