In the previous post, we covered the applications of industrial-grade filters, like the ones offered by Micro Lube. In this post, we’ll review the different types of filters that are used for commercial and industrial purposes as well as the reasons for using them.
Filtration is the process of removing unwanted particles from a fluid. This includes the removal of solid particles from fluid in a gaseous or liquid state.
To achieve the separation, a medium known as a filter is used. Filters can be used to remove contaminants in gas, liquid or solid state.
Several different types of filtrations are being used today:
Centrifugal filtration is a type of filtration system that achieves filtration by subjecting the filter body to a rotational movement. It doesn’t involve arranging a medium for initiating the filtering process. At a predetermined rotational movement of the filtering equipment, the high-density fluids are separated from the low-density fluids. This process is typically used for fluids in liquid or semi-liquid state.
Gravity filtration is a type of filtration used to separate suspended solids from a liquid fluid. It requires the fluid to flow from the top level to the lower surface. Atmospheric pressure is responsible for initiating this filtration process.
Vacuum filtration is a type of filtration that uses suction or static pressure level to remove suspended dust particles from atmospheric air or liquid.
To initiate the cold filtration technique, you need to achieve a predetermined low temperature. It may even require subzero temperatures. It is effective at removing proteins and fatty acids that may get mixed in with the fluid in the preceding process.
After attaining the low temperature, the fluid is passed through a filter that separates the frozen suspended particles.
Hot filtration is effective at removing traces of impurities from crystalline compounds. It requires the crystalline compounds to be dissolved in a solvent at a high temperature. The unwanted particles are removed by flowing the liquid compound through a medium. The compound is slowly cooled to yield purified crystalline compounds.
Also known as a sand filter, different forms of the multi-layer filtration system have been around for centuries. A bed of gravel is used to filter the removable particles from water. A carbon bed uses coal carbon to treat the colour and odour of the distilled water.
Mechanical filtration is a relatively new filtration technique. It’s used to cater to industrial filtration needs at pressures higher than the atmospheric pressure. To achieve this type of filtration, a medium is arranged within the main filter body.
Surface filtration involves arranging a filter on the contact surface of the medium. For instance, the use of a strainer for separating tea from the residue.
Depth filtration involves the use of a medium having graded density structure for collecting different dust particles within its container. Depth filtration can be used for filtering particles from drinking water.
