About Necessity of Revision of Standard Silicon Content in Potable Water

Summary

Substantiation for increasing the value of allowable concentration of silicon dissolved in potable water is made; it will bring the domestic normative documents into accord with international standards, ensure more rational use of resources. In Russia the maximum allowable concentration of silicon is established in SanPiN for anthropogenic silicon and silicon used for water treatment that’s why the limitation on the use of natural water containing natural silicon is unlegitimate. The literary review of water desiliconization technologies is done. Data on reduction in content of dissolved silicon in the course of deferrization and demanganization of underground water with generation of coagels, reciprocal precipitation and sorption on ferriferous deposits generated are presented. In the course of intraformational deposition, reduction in silicon content up to 35–50% is reached.
