Case Study

Optimizing Sludge Chemical Conditioning with the Cationic Polymer AquaFloc CP470H

We were consulted by the managers of a wastewater treatment plant in northern Algeria to supply a cationic polymer used in their activated sludge dewatering process with a belt filter press.

Product Selection

To select the right product and best meet our client's needs, we followed a three-step process:

1

Jar test

Performed in our laboratory to select the appropriate product, after collecting a sludge sample from the WWTP.

2

Lab Trial

A sample of the selected product was sent to our client for confirmation.

3

Industrial Trial

A product quantity was provided free of charge to be tested on their belt filter press.

AquaFloc CP470H passed all three tests and was selected by the client.

AquaFloc CP470H

AquaFloc CP470H is a high molecular weight, highly cationic acrylamide polymer. It is used as a flocculation aid to improve solid/liquid and liquid/liquid separations.

Features and benefits

  • Improves the performance of wastewater treatment facilities (settlers, flotation units, belt filter presses, oil separators, etc.).
  • Reduces sludge volume and therefore disposal costs, and enables landfilling (lower moisture content).
  • Improves wastewater quality by reducing parameters such as SS, COD, BOD, etc.

Results

After applying AquaFloc CP470H, the client achieved the following results:

−50%

Reduction in polymer dosage

★★★★★

Excellent sludge consistency
