Here’s a list of out services. If you find something that may help you, let us know.

Thickening tests

Static and dynamic thickening test data can be collected to determine thickener sizing and operating parameters. The type of testing to be conducted will be determined by both the type of thickener desired and by the amount of sample available for testing.

Key Benefits

  • Determination of Required Thickener Sizing for a Given Slurry
  • Prediction of Potential Thickener Performance
  • Recommendations for Thickener Operation Parameters

Filtration tests

Vacuum and/or pressure filtration tests can be conducted on relatively small quantities of sample slurry. Tests conducted will collect a general set of data that would describe filter operation and performance in terms of production rate and achievable cake moistures.

Key Benefits

  • Unit Production Rates Determined for Vacuum Filters (Disc, Drum & Belt)
  • Filter Press Sizing Determined for Horizontal or Vertical Presses Filter
  • Performance Prediction (Wash Efficiency, Cake Moisture, etc.)

 

Pulp Rheology (Viscosity Measurement)

Tests to determine apparent viscosity at known shear rates relative to solids concentration at known temperature and pH. Data analysis to determine the yield value for the slurry at various solids concentrations.

Key Benefits

  • Determination of slurry sample viscosity at various conditions
  • Development of flow curve for slurry sample at various conditions
  • Development of correlation between yield value vs. solids concentration for slurry sample at various conditions
  • Characterization of slurry sample as Newtonian vs. non-Newtonian

Flocculant Evaluation & Selection

Static clarification tests can be conducted on each distinct sample. The effect that, flocculant dosage, underflow density and other controllable physical parameters, within flowsheet constraints, has on Unit Area can be examined.
