Project location Outside the UK
Products used SALOMIX™ SSA agitator
 
 

Overview

The world’s first SALOMIX SSA agitator has been installed by a leading European pulp and paper producer with a long tradition in testing new technologies, to cut its energy bill, without compromising the process up-time.

Challenge

To save energy in an already optimised process is not an easy task. The client had the opportunity to install the new SALOMIX SSA agitator in a fibre recovery tank in the mill’s wastewater treatment process. The tank has a pulp consistency of 2-5%. The previous cantilever type agitator was installed with a variable speed drive and a 15kW motor. The normal consistency is about 2-3%, so the previous agitator was optimised with reduced speed, running at less than 40Hz. Power savings for the SALOMIX SSA can, therefore, be evaluated at the same agitation level as for the previous agitator.

Solution

Sulzer delivered a SALOMIX SSA agitator to replace the existing cantilever type of agitator.

  • Supply of one SALOMIX SSA60 agitator
  • Newly developed EX3 propeller with high efficiency
  • Sturdy bearing frame with a minimal bearing lifetime of 200,000 hours
  • Strong and reliable belt drive unit
  • The existing motor and frequency converter were utilised

Comment

"We continuously strive to lower the environmental impact and increase the competitiveness of our customers."
