Silica removal
(OP)
Does anyone have experience of removing silica from water or salt solutions with polyaluminium chloride (PAC) or with other flocculation process like co-precipitation it with magnesium hydroxide?
Thank you for your time, Lattar

The old Drew water handbook has an excellent discussion about the chemistry.
Arbochim, the problem is reducing silica in a solution not dissolving more into the solution.

To remove the reactive silica you need another process such as those described above. Membrane process are also commonly used for silica removal. Which you choose depends on the concentration of silica in the water and what the water is going to be used for.
