Silica is a naturally occurring impurity found in many water sources. It may exist in dissolved, colloidal or reactive forms. Silica is important because it can be difficult to remove completely and may pass through some purification stages more easily than common ionic contaminants.
In high-purity laboratory water systems, silica can become a concern in trace analysis and certain sensitive applications.
Silica may come from:
Feed water silica levels vary significantly depending on the water source.
Silica can interfere with some analytical methods and may contribute to contamination in trace-level analysis. Colloidal silica can also contribute to fouling in membranes and filters.
Silica contamination can cause:
Silica may not always be fully indicated by standard conductivity or resistivity measurement, depending on its form.
Silica can be controlled using:
In critical applications, silica should be considered during system selection and feed water evaluation.
Silica may affect:
