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 granules where dry-blend stability and bulk handling matter more. Grade selection follows the make-up method rather than the application name. Zhongzhi Chemical supplies both grades from China at iron ≤0.02%, with COA, SDS and REACH documentation.
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 / 50 kg bags and 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 ≤ 0.02% | Effective cleaning without introducing iron residue |
| Export to international distributors | COA, SDS and REACH documentation per shipment | Clears customs and downstream qualification |
Pentahydrate for controlled dissolution applications. Granules for dry-blend stability and bulk handling.
