Silica in water treatment.

There are multiple treatment options available for removing silica from water. At levasil colloidal silica we contribute to your success with innovations in silica chemistry. Silica ion exchange system can complement any water treatment system if there is a need to remove the silica from water specifically. This colloidal silica is not ionised and therefore is not properly eliminated by traditional systems used in the treatment of boiler water clarification ion exchange see chapter treatment and conditioning of industrial water and poses severe problems scaling vapor quality.

The particle size distribution shall be determined on samples taken at the point of manufacture using the method of test given in en 12904. It could be silica. Consequently supplementary methods have been developed. Dissolved silica is best removed through reverse osmosis while colloidal silica is best removed through ultrafiltration.

Water treatment of silica. Analysis of silica sand and silica gravel for water treatment. Silica is present in all natural water supplies in some form. But in some cases even with this type of treatment the film and etching problems persist.

Silica can be present in the form of granules colloids or reactive ions and selecting the appropriate silica removal technology depends on which physical forms of silica are. Determining which removal process is most appropriate is dependent on whether the silica is in a dissolved or colloidal form. Natural waters generally contain about 5 8 mg l of silica si0. Silicon dioxide or silica sio2 is an oxide of the element silicon which is the second most abundant element found on earth.

Silica removal is deployed for a variety of industrial applications including treatment of raw water cooling tower makeup water boiler feed and blow down water. Particle size distribution of filter media of silica sand and silica gravel.
