2. Iron oxide adsorption - Wikipedia

   en.wikipedia.org/wiki/Iron_oxide_adsorption

   Arsenic is a common natural contaminant of well water and is highly carcinogenic. Iron oxide adsorption treatment for arsenic in groundwater is a commonly practiced removal process which involves the chemical treatment of arsenic species such that they adsorb onto iron oxides and create larger particles that may be filtered out of the water stream.

3. Deoxidization - Wikipedia

   en.wikipedia.org/wiki/Deoxidization

   Oxidation is the process of an element losing electrons. For example, iron will transfer two of its electrons to oxygen, forming an oxide. This occurs all throughout as an unintended part of the steelmaking process. Oxygen blowing is a method of steelmaking where oxygen is blown through pig iron to lower the carbon content.

4. Water heat recycling - Wikipedia

   en.wikipedia.org/wiki/Water_heat_recycling

   Installation of a double-walled copper-on-copper heat exchanger in a vertical section of the master drain line in a Canadian home (2007) Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery, [citation needed] or sometimes shower water heat recovery [citation needed]) is the use of a heat exchanger to recover energy and reuse heat ...

5. Iron-oxidizing bacteria - Wikipedia

   en.wikipedia.org/wiki/Iron-oxidizing_bacteria

   The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...

7. Phase-change material - Wikipedia

   en.wikipedia.org/wiki/Phase-change_material

   The packaging material should conduct heat well; and it should be durable enough to withstand frequent changes in the storage material's volume as phase changes occur. It should also restrict the passage of water through the walls, so the materials will not dry out (or water-out, if the material is hygroscopic).
