DeWatering System Parameters




Method Overview

  • Typically a grab sample from the hydrocyclone underflow.
  • Sampled in accordance with EPRI Method A1.

Target Compounds

  • Solids content;
  • Liquid content;
  • Water-Soluble Solids content.

Performance Tips

Parameter Suggested Method of Analysis Description of Method Suggested Frequency Use of data
Thickener or hydrocyclone underfloow solids content EPRI Method F1 Gravimetric Start and finish of each performance test run Troubleshoot process and calibrated lime density parameters
Clarifying water, water analysis (anions, cations & suspended solids) Can vary depending on parameter of interest. See table of Recirculation Slurry/Blowdown Analysis Start and finish of each performance test run Monitor thickener performance
Supernatent, filtrant solids content (% by wt) EPRI Method E1 Gravimetric Start and finish of each performance test run Monitor filter cloth status

Shipping

  • Acetone must be shipped as a hazardous material. Please call for IATA codes if you need them.
  • Samples may be shipped at ambient temperatures (or at preservations temperatures specified by individual parameter);
  • It may prove more economical to keep acetone rinses separate, ship other samples normally, and the acetone as hazardous.
  • Be sure to include a chain of custody for each shipping container.
