Filtration topics include: Filtration fundamentals and equipments, filtering cake resistance, filtering medium resistance, filtration at constant pressure drop and volumetric flow. Filtration is a physical process that separates solid matter from a fluid using a filter medium. The filter medium has a complex structure that only allows the fluid to pass through. The basic requirements for filtration are: A filter medium A fluid with suspended solids A driving force, such as a pressure difference, to cause fluid to flow A mechanical device (the filter) that holds the filter medium,...

Filtration is a physical process that separates solid matter from a fluid using a filter medium. The filter medium has a complex structure that only allows the fluid to pass through. The basic requirements for filtration are: A filter medium A fluid with suspended solids A driving force, such as a pressure difference, to cause fluid to flow A mechanical device (the filter) that holds the filter medium, contains the fluid, and permits the application of force Filtration depends on pore sizes. Smaller pores can screen out more particles, but it also takes more energy to force the liquid through. Here are some types of filtration: Membrane filtration: Membrane filters act as a barrier to separate contaminants from water. They are microporous barriers of polymeric, ceramic, or metallic materials. Vacuum filtration: In vacuum filtration, the liquid passes through a filter paper placed in a funnel. The filtration driving force is the applied vacuum. Suction filtration: Suction filtration (vacuum filtration) is the standard technique used for separating a solid-liquid mixture when the goal is to retain the solid.
