Combined biological cleaning agents

Combined biologial waste water cleaning agents we strongly recommend especially for the optimisation of industrial and municipal waste water treatment plants. The balanced combination of inorganic and organic charge carriers provide the best possible
conditions for the existing biocoenosis to run the decomposition process reliably.
 

  • bulking and floating sludge
  • foam and suspended
    microflocs in the outlet

  • inadequate phosphate removal
  • occurence of heavy metals, copper, ...
  • high contaminated seeping waters

 

With biological cleaning agents you will be able to counter all these problems effectively,
with the use of just one combined product.
 

The results:

  • optimised flocculent structure
  • improved sedimentation properties = higher COD-reduction
  • integration of filamentous bacteria
  • increased species diversity
  • reduction in the quantity and improved properties of excess sludge
  • increased anaerobic gas yields

Experiences from practice:

After taking a sample of activated sludge and finishing with an on-the-spot jar test the agents can be added, undiluted, to the inlet or outflet of the aeration basin. As a rule, the data obtained during a trial period are evaluated daily and summarised in a test report. This makes it possible to react quickly to changes and, if necessary, adapt process parameters such as excess sludge quantity, MLSS content, return sludge or dosing rate to the new situation.

The application of the agents leads to stable plant operation under fluctuating conditions. The smallest dosing rates of 15-30 ppm are already sufficient to reach a seasonally stable, low sludge index. In optimising an industrial biological waste water treatment plant, a dosing rate of 25 ppm was sufficient to reach a sustained sludge index of less than 100 ml/g.

The outstanding sedimentation properties of the activated sludge lead to a significant increase in the MLSS content, making a short-term increase in capacity possible without restructuring.

An additional benefit is the coagulation of the microflocs and the precipitation of phosphate. With the reduction in the quantity of excess sludge, the improved dewatering and the increased anaerobic gas yield, those agents represent not only a technical innovation but also an economical alternative to conventional, inorganic precipitation agents.
