Study Notes
Filtration Definition and Process
- Filtration is the process of separating solid from liquid or gas using a porous medium.
- Filtration is a unit operation where a feed or slurry is forced through a porous medium, separating solids from liquids.
Clarification and Filtration
- The term "clarification" is applied when the goal of filtration is to obtain a clear liquid.
Slurry Characteristics
- The characteristics of the slurry (suspension of solid and liquid to be filtered) that affect filtration include factors identified by Dr. Radwa Mahrous.
Filter Medium
- The filter medium used to retain solids is called the filter cake.
Surface Filtration
- The primary principle of surface filtration is the retention of solids on the filter medium surface.
Darcy's Law and Filtration Rate
- The rate of flow in filtration is based on Darcy's law, which can be expressed as an equation.
- The rate of filtration is proportional to the pressure drop and inversely proportional to the viscosity of the fluid.
Filter Medium Area and Filtration Rate
- An increase in the area of the filter medium will increase the volume of filtrate flowing from the filter.
Permeability Coefficient
- The permeability coefficient affects the rate of filtration and is influenced by the surface area of particles and the porosity of the cake.
Cake Formation and Filtration
- Cake formation is the process of solids accumulating on the filter medium during filtration.
- Increasing the thickness of the cake will decrease the rate of filtration.
Sterilization and Filtration
- Filtration is not typically used for sterilizing solutions that are chemically or physically unstable under heating conditions.
