A granular-grade enquiry should define the particle measurements and water-treatment duty that matter to the project. This industrial sodium metasilicate pentahydrate, Na2SiO3·5H2O, is described as white granules with 99% purity, Na2O content of 28.5–30.0% and easy water solubility.
Identify the water-treatment material duty
Describe the actual process and the measurements that determine material and treatment acceptance. A water-treatment direction provides an enquiry context, while achieved performance and operating conditions need relevant evidence from the intended project.
Specify what the granular form must meet
Request measured particle data and its method for the actual supplied granules. White granular appearance does not define a size distribution or dissolution rate, so any accepted particle or rate requirement should be stated before a meaningful grade comparison.
- Form evidence
- Actual supplied granules and method-defined particle measurements.
- Chemical evidence
- Current purity and Na2O bases with the required impurity limits.
Review composition and documents before the trial
Keep the overall purity and Na2O content as separate analyses and obtain their current reports. Request safety and technical documents and applicable ISO scope, because identity and composition do not provide numerical alkalinity, modulus, a universal dose or a premium treatment result.
Samples are available, with current terms and storage and shelf-life conditions to agree. Provide the intended water duty and requested granule evidence in the enquiry so the comparison is tied to an actual material specification and qualification trial without an assumed particle profile or finished-process benefit.
