Dear Sirs/madum
How to remove silica from R O Plant feed water.
Kindly advice.

Reactive silica solubility in water depends on the pH and increases as pH increases from 7 onwards. Soda ash has a component of CO2 Which forms carbonic acid decreasing pH. Hence the lower pH precipitates reactive sliica.
Solute silica may be in form of silica gel. Silica is usually made up of silicon which is combined with oxygen.
Rhyolite is felsic and thus silica rich.
Any metrial or thing which containts silica in it is call silica content..
High silica magma is more viscous (sticky) than low silica magma, so low silica magma lows easier.

OPC is ordinary Portland cement and PPC is Portland pozolona cement. OPC is obtained by grinding clinker and gypsum whereas PPC is obtained by grinding clinker gypsum and high reactive silica. High reactive silica improves the quality of cement by reducing liberated lime.
Sand is very inert, it is mainly silica, SiO2. Glass is essentially silica in fact it is slightley more reactive than pure silica. Common acids do not affect silica, e..g hydrochloic, sulfuric, nitric but HF doee react with silica.
Diatomaceous earth, composed of the skeletons of tiny animals would be good, for it is finely divided, and thus quite reactive.
Silica is colorless.

Yes. Silica is everywhere.
where can silica mineral can be found
The chemical compound silica is an oxide of silicon .In other words; silicon is in silica.
