  2. Copper zinc water filtration - Wikipedia

    en.wikipedia.org/wiki/Copper_zinc_water_filtration

    Copper zinc water filtration is a high-purity brass water filtration process that relies on the redox potential of dissolved oxygen in water in the presence of a zinc anode and copper cathode. It uses dissolved impurities within water as constituent substrate, which are reduced to more physiologically inert compounds.

  3. Fluid flow through porous media - Wikipedia

    en.wikipedia.org/wiki/Fluid_flow_through_porous...

    In fluid mechanics, fluid flow through porous media is the manner in which fluids behave when flowing through a porous medium, for example sponge or wood, or when filtering water using sand or another porous material. As commonly observed, some fluid flows through the media while some mass of the fluid is stored in the pores present in the media.

  4. Diatomaceous earth filtration - Wikipedia

    en.wikipedia.org/wiki/Diatomaceous_earth_filtration

    Pressure filter systems have a water inlet and outlet with the inlet site at the top and the water outlet at the base of the filter. As the water flows through water inlet, it will encounters a grid assembly covered in synthetic cloth which provides support for the diatomaceous earth cake. [ 19 ]

  5. Filtration (probability theory) - Wikipedia

    en.wikipedia.org/wiki/Filtration_(probability...

    A filtration is called an augmented filtration if it is complete and right continuous. For every filtration F {\displaystyle \mathbb {F} } there exists a smallest augmented filtration F ~ {\displaystyle {\tilde {\mathbb {F} }}} refining F {\displaystyle \mathbb {F} } .

  6. Percolation - Wikipedia

    en.wikipedia.org/wiki/Percolation

    For example, in geology, percolation refers to filtration of water through soil and permeable rocks. The water flows to recharge the groundwater in the water table and aquifers . In places where infiltration basins or septic drain fields are planned to dispose of substantial amounts of water, a percolation test is needed beforehand to determine ...

  7. Water filter - Wikipedia

    en.wikipedia.org/wiki/Water_filter

    A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation , accessible drinking water , public and private aquariums , and the safe use of ponds and swimming ...

  8. Filtration - Wikipedia

    en.wikipedia.org/wiki/Filtration

    Filtration occurs both in nature and in engineered systems; there are biological, geological, and industrial forms. [2] In everyday usage the verb "strain" is more often used; for example, using a colander to drain cooking water from cooked pasta. Oil filtration refers to the method of purifying oil by removing impurities that can degrade its ...

  9. Microfiltration - Wikipedia

    en.wikipedia.org/wiki/Microfiltration

    Cross flow filtration is understood to be a unit operation rather than a process. Refer to Figure 2 for a general schematic for the process. Dead-end filtration; all of the process fluid flows and all particles larger than the pore sizes of the membrane are stopped at its surface. All of the feed water is treated at once subject to cake ...
