FlocStirr

FlocStirr – Inline polymer mixer

Efficient and optimally effective admixture of polymers

The problem :

The floc formation is a critical part of polymer-initiated flocculation processes. The floc quality and formation are significantly influenced by the following aspects:

  • The quantity, mixing type and quality of the flocculation agent
  • The reaction period of the flocculation agent in the sewage sludge until the following dewatering phase
  • The sludge type (consistency and contents)
  • A downstream mechanical flocculation method (FlocFormer)

It is generally accepted that a high floc quality has a significant influence on the dewatering performance.

The dynamic FlocStirr inline polymer mixer (design and inner workings, bold display):

With our inline mixers, we have put years of research experience into practice.

The principal of best practice has proven itself many times over. Details of how and why we have consistently implemented the eleven most important requirements for a polymer mixer we will show you on demand. By using our mixers, you can maintain firm control of the mixing process. We have concentrated all of our years of test results and targeted improvements into our range of inline mixers. Take advantage of our mixing expertise using many different sludges and polymers under a wide range of operating conditions.
Our mixers are also integrated in our FlocFormer, thus leading to optimal flocculation (pelleting) when used in combination with this peerless mechanical floc treatment process. The dewatering results are extremely impressive as a result. By using our technologies, we have been able to reduce polymer consumption by up to 30% whilst simultaneously achieving improvements in dry solid content of up to 20%. This then leads to short amortisation periods.

Furthermore, it is possible to control it directly by a fixed frequency converter on the motor.
With the inline mixers from aquen, you can improve your mixing results and reduce polymer consumption up to 30%. The short amortisation periods mean that the replacement of existing mixers is also justified.
