Filtration is a physical separation process that separates solid matter and fluid from a mixture using a filter medium that has a complex structure through which only ...
The most comprehensive history of water filtration was published by Moses N. Baker in 1948 and reprinted in 1981. [19] In the 1800s, mechanical filtration was an industrial process that depended on the addition of aluminium sulfate prior to the filtration process. The filtration rate for mechanical filtration was typically more than 60 times ...
Depth filters are filters that use a porous filtration medium to retain particles throughout the medium, rather than just on the surface of the medium. Depth filtration, typified by multiple porous layers with depth, is used to capture the solid contaminants from the liquid phase. [1]
The dead-end filtration process is usually a batch-type process, where the filtering solution is loaded (or slowly fed) into the membrane device, which then allows passage of some particles subject to the driving force. The main disadvantage of dead-end filtration is the extensive membrane fouling and concentration polarization. The fouling is ...
A HEPA bag filter can be used in conjunction with a pre-filter (usually carbon-activated) to extend the usage life of the more expensive HEPA filter. [23] In such setup, the first stage in the filtration process is made up of a pre-filter which removes most of the larger dust, hair, PM10 and pollen particles from the air. The second stage high ...
