Application

Domestic sludge Standard Reference Material (SRM) is intended primarily for the evaluation of methods employed in analyzing sludges and other materials of a similar matrix.

Caractéristiques et avantages

  • Accompanied with certified mass fraction values for elements that are metrologically traceable to the SI unit for mass expressed as percentages or milligrams per kilogram.
  • Reference mass fraction values are provided, along with both elemental and organic constituents, which are noncertified values serving as the best estimates of true values.
  • Information mass fraction values are also provided for organic constituents.
  • Expiration details, storage, and instructions for use are provided on the NIST certificate.

Questions

  1. From where was this fine sludge procured?

    1 answer
    1. The U.S. Geological Survey (USGS), under contract to NIST, obtained partially dehydrated sewage cake material from the Metropolitan Denver Sewage Disposal District No. 1. The material (approximately 182 kg) was placed in plastic-lined drums and transported to the USGS facilities (Lakewood, CO) for processing. It was dried at ambient temperature in a forced air chamber, ground to pass a 74 µm (200 mesh) sieve, blended for 24 h to assure homogeneity of the pulverized material. Test samples were taken from the blender for preliminary homogeneity analyses. The material was then radiation sterilized. The sterilized material was shipped in bulk to NIST, where the material was bottled in 40 g units after reblending for 4 h.
