  2. Media filter - Wikipedia

    en.wikipedia.org/wiki/Media_filter

    Municipal drinking water systems often use a rapid sand filter and/or a slow sand filter for purification. Silica sand is the most widely used medium in such filters. [1] Anthracite coal, garnet sand, ilmenite, granular activated carbon, manganese green sand and crushed recycled glass are among the alternative filter media used. [2]

  3. Greensand - Wikipedia

    en.wikipedia.org/wiki/Greensand

    Greensand glauconite is used as a water softener for its chemical-exchange properties. Greensand coated with manganese oxide (called manganese greensand) is used in well water treatment systems to remove dissolved (reduced) iron and manganese with the addition of an oxidant, usually potassium permanganate, under controlled pH conditions. [14]

  4. Manganese - Wikipedia

    en.wikipedia.org/wiki/Manganese

    Manganese is a key component of low-cost stainless steel. [ 73 ] [ 74 ] Often ferromanganese (usually about 80% manganese) is the intermediate in modern processes. Small amounts of manganese improve the workability of steel at high temperatures by forming a high-melting sulfide and preventing the formation of a liquid iron sulfide at the grain ...

  5. Iron-oxidizing bacteria - Wikipedia

    en.wikipedia.org/wiki/Iron-oxidizing_bacteria

    Any previously precipitated iron is removed by simple mechanical filtration. Several different filter media may be used in these iron filters, including manganese greensand, Birm, MTM, multi-media, sand, and other synthetic materials. In most cases, the higher oxides of manganese produce the desired oxidizing action.

  6. Sand filter - Wikipedia

    en.wikipedia.org/wiki/Sand_filter

    Sand filter. Sand filter used for water treatment. Sand filters are used as a step in the water treatment process of water purification . There are three main types; rapid (gravity) sand filters, upward flow sand filters and slow sand filters. All three methods are used extensively in the water industry throughout the world.

  7. Manganese nodule - Wikipedia

    en.wikipedia.org/wiki/Manganese_nodule

    Manganese nodule. Polymetallic nodules, also called manganese nodules, are mineral concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as a potential economic interest. [ 1]

  8. Moving horizon estimation - Wikipedia

    en.wikipedia.org/wiki/Moving_Horizon_Estimation

    Moving horizon estimation ( MHE) is an optimization approach that uses a series of measurements observed over time, containing noise (random variations) and other inaccuracies, and produces estimates of unknown variables or parameters. Unlike deterministic approaches, MHE requires an iterative approach that relies on linear programming or ...
