What does silica in water mean in practice?
May form difficult-to-remove deposits on glass, membranes and heating surfaces, especially after water thickening.
When does it matter?
The behavior of silica depends on pH, temperature and form, which is why a regular softener does not remove it.
Which solutions are related to it?
Membrane recovery, pH and concentration are controlled; uses RO, specialized coagulation or anion exchange in demanding processes.
