  2. Cross-flow filtration - Wikipedia

    en.wikipedia.org/wiki/Cross-flow_filtration

    The principal advantage of this is that the filter cake (which can blind the filter) is substantially washed away during the filtration process, increasing the length of time that a filter unit can be operational. It can be a continuous process, unlike batch-wise dead-end filtration. Diagram of cross-flow filtration

  3. Filtration - Wikipedia

    en.wikipedia.org/wiki/Filtration

    Diagram of simple filtration: oversize particles in the feed cannot pass through the lattice structure of the filter, while fluid and small particles pass through, becoming filtrate. 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 ...

    Added small particles to retentate stream, as a filter cannot produce a retentate free of "permeate" fluid. Note to users: this diagram shows crossflow filtration. 08:40, 4 February 2007: 411 × 256 (42 KB) LadyofHats: trying to make it show: 08:39, 4 February 2007: 371 × 231 (42 KB) LadyofHats

  5. Büchner funnel - Wikipedia

    en.wikipedia.org/wiki/Büchner_funnel

    It is commonly thought to be named after the Nobel Laureate Eduard Buchner (without umlaut), but it is actually named after the industrial chemist Ernst Büchner. [2] A Büchner funnel fitted with Sintered Disc made of Boro 3.3 Glass. Diagram of filtration set-up using a Büchner flask

  6. Suction filtration - Wikipedia

    en.wikipedia.org/wiki/Suction_filtration

    Diagram of the vacuum filtration apparatus. By flowing through the aspirator, water will suck out the air contained in the vacuum flask and the Büchner flask.There is therefore a difference in pressure between the exterior and the interior of the flasks : the contents of the Büchner funnel are sucked towards the vacuum flask.

  7. Membrane technology - Wikipedia

    en.wikipedia.org/wiki/Membrane_technology

    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 ...

  9. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Filtration depends on the development of a thin biological layer, called the zoogleal layer or Schmutzdecke, on the surface of the filter. An effective slow sand filter may remain in service for many weeks or even months, if the pretreatment is well designed, and produces water with a very low available nutrient level which physical methods of ...
