WebCake Filtration. When liquids contain high solid loads, cake filtration is often used as a physical filtration technology. The liquid passes through the filter medium while the solids form a layer on its surface. During the filtration cycle, this layer retains other particles and becomes thicker, creating the ‘filter cake’.
