Sodium Metasilicate for Water Treatment
Water treatment chemical producers use sodium metasilicate in pH adjustment blends, equipment cleaning formulations, and multi-component treatment packages.
Updated
Short answer
Water treatment chemical producers use sodium metasilicate for pH adjustment blends, equipment cleaning formulations and multi-component treatment packages. Specify the pentahydrate grade (Na₂SiO₃·5H₂O, CAS 10213-79-3) where a controlled dissolution profile suits the make-up method, and anhydrous granules where dry-blend stability and bulk handling matter more. Grade selection follows the make-up method rather than the application name. Iron is typical ≤80 ppm on pentahydrate and typical ≤100 ppm on anhydrous. SDS, TDS and a representative COA are available for buyer review. EU REACH status and importer coverage must be confirmed separately against the requested substance identity, supply chain, annual tonnage and importer legal entity. Please request a compliance review before quotation.
How Sodium Metasilicate Is Used
- pH buffering in water treatment chemical blends
- Cleaning formulations for membranes, pipes, and equipment
- Dry-blend packages for field application and dosing
- Combined procurement with other silicate chemicals
Benefits for This Industry
- Predictable dissolution with pentahydrate grade
- Bulk packaging: 25 kg PP woven bags with PE liner and 1,000 kg FIBC jumbo bags
- Export documentation for international distributors
- Grade, packing, loading quantity, and document requirements confirmed before RFQ
How Our Sodium Metasilicate Supports This Application
| Formulation need | Product feature | Value to your line |
|---|---|---|
| Reliable pH buffering in treatment blends | Strongly alkaline metasilicate with buffering capacity | Holds target pH across multi-component treatment packages |
| Controlled dissolution in blend make-up | Pentahydrate hydrated grade (CAS 10213-79-3) | Milder, more predictable dissolution for blended packages |
| Dry-blend stability and bulk handling | Free-flowing granules | Stable storage and consistent dosing in field packages |
| Cleaning membranes, pipes and equipment | Alkaline silicate cleaning action; iron is a typical value on the TDS | Effective cleaning without introducing iron residue |
| Export to international distributors | SDS and batch COA per shipment; EU REACH reviewed separately | Document set is confirmed against the grade and the importer before shipment |
Pentahydrate for controlled dissolution applications. Granules for dry-blend stability and bulk handling.

FAQ
Can I order multiple grades for water treatment blends?
Yes. Combined FCL shipments of pentahydrate, granules, and sodium silicate are supported.
