2. Clarifying agent - Wikipedia

   en.wikipedia.org/wiki/Clarifying_agent

   For example, a flocculant may be used in swimming pool or drinking water filtration to aid removal of microscopic particles which would otherwise cause the water to be turbid (cloudy) and which would be difficult or impossible to remove by filtration alone. Many flocculants are multivalent cations such as aluminium, iron, calcium or magnesium. [1]

3. Flocculation - Wikipedia

   en.wikipedia.org/wiki/Flocculation

   Calcium salts can be added to cause flocculation, or the process can be reversed by removing calcium by adding phosphate to form insoluble calcium phosphate, adding excess sulfate to form insoluble calcium sulfate, or adding EDTA to chelate the calcium ions. While it appears similar to sedimentation in colloidal dispersions, the mechanisms are ...

4. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   This is the "fur" that builds up on kettle elements, etc., in hard water areas. With the exception of calcium, boiling does not remove solutes of higher boiling point than water and in fact increases their concentration (due to some water being lost as vapour). Boiling does not leave a residual disinfectant in the water.

5. Montmorillonite - Wikipedia

   en.wikipedia.org/wiki/Montmorillonite

   Montmorillonite is used in the oil drilling industry as a component of drilling mud, making the mud slurry viscous, which helps to keep the drill bit cool, and to remove drilled solids. It is also used as a soil additive to hold soil water in drought-prone soils, used in the construction of earthen dams and levees , and to prevent the leakage ...

7. Clarifier - Wikipedia

   en.wikipedia.org/wiki/Clarifier

   Addition of flocculants is common to aid separation in clarifiers, but density difference of flocculant concentrate may cause treated water to have an excessive flocculant concentration. Uniform flocculent concentration can be improved and flocculant dosage reduced by installation of an intermediate diffused wall perpendicular to the flow in ...
