Silica and scaling problems in geothermal power plants

Silica while in the form of silicic acid can form hard glassy scales and also combine with various metals to form various silicates that can also cause scaling. There exist various methods to control silica scaling so it doesnt cause too many problems for heat exchangers and surface piping in geothermal power plants.

Behavior of Silica in Ion Exchange and Other Systems

Behavior of Silica in Ion Exchange and Other Systems

The molybdate reactive silica test will only expose one, or possibly two, of the Si atoms in a chain of polymerized silica. This means that the molybdate reactive silica test will only measure part of the total silica that may be in solution. This phenomenon gives rise to the term giant silica and also to what many people consider colloidal ...

Silicon Si in a chemically combined form is ubiquitous in nature. The Si content of soils can vary dramatically from 1 to 45 dry weight Sommer et al., 2006 , and its presence in the form of silicic acid Si OH 4 or its ionized form, Si OH 3 O , which predominates at pH 9 allows its uptake by plants.
