The standard procedure for preparing sewage sludge for dewatering is a chemical conditioning by polymers. The task of an optimized conditioning is to optimize the flock structure in interconnection with highly variable sludge and process parameters. Todays technique doesn’t reach this aim. Different dewatering units demand for a specific flocculation process. Thus, the dewatering results are as good as the conditioning step.

Our solution:

The international patent-protected flocculation unit FlocFormer can be adapted to various conditions and is tailor made for separation processes supported by polymers. Four adjustable degrees of freedom enables the system to be used at different flow rates and meets a high flexibility towards changing sludge properties and dewatering machines.

Ingenious thing:
The FlocFormer realizes a two step process; initially the flocculation agent is injected into a rapid mixer which results in high volume flocs with low shear stability. Then they are eroded and compacted in the flocculation reactor. The polymer can develop its full performance and an overdose is not necessary anymore.

  • The application of FlocFormer improves your dewatering results for about 25%, irrespective of the mode of dewatering e.g. by chamber filter press, counter-current centrifuge, drum sieve or screw press. The higher dry solid content saves disposal costs or energy consumption in case of incineration.
  • The filtrate quality improves considerably and the reload of the waste water treatment plant declines. The consumption of polymer will diminish for about 30% and analogue the cost of operation will decrease.

Advantages of the process at a glance:

  • Reduced disposal costs due to reduced sludge amount and higher dry solid content.
  • Minimized polymer consumption, therefore reduced operation costs.
  • More stable process conditions.
  • Improved filtrate quality, therefore less reload of the waste water treatment plant.
  • Plug & Play concept.
  • Short amortization period.
  • Combination suggestive and possible with all established separation processes.
