Why test your sludge at Alfa Laval’s full testing lab?

  • Whether a new application, retrofit, or a change in process, testing ensures you are provided with the best solutions
  • Sample can be tested for performance for a range of different technologies – to help identify optimum equipment for your process
  • Testing can determine process changes that can be made to improve performance
  • When testing a representative sample of sludge, a performance guarantee can be made

The lab testing process

Your sample will arrive at Alfa Laval’s ISO 9001 certified lab in a specialized sample container (provided to you by Alfa Laval).  Sludge characteristic testing (solids, pH, temperature, volatiles, etc.) will be the first step to verify properties.  Polymer screening will then occur to investigate performance and flocculation properties of the sludge for a range of different polymer options. Then the product/polymer combinations will be tested for a variety of equipment types to help determine technology options. 

Finally, a full report will be created detailing the characteristics determined, as well as polymer and equipment recommendations. Complete testing takes 1-2 business weeks.
