Precipitation, flocculation and sedimentation

Proven, resilient process for wastewater treatment that has been used successfully for many decades.

Safe treatment of wastewater to required limit values

In the precipitation process, dissolved ions are converted into insoluble compounds in physico-chemical reactions triggered by the addition of suitable chemicals that are partly developed in-house. In the subsequent flocculation process, tiny solid particles coalesce to form larger-size flocs. Both process steps can be designed for use in batch operation or continuous operation mode (stirred-tank cascade), depending on the type and quantity of wastewater.

Once we have created your tailor-made plant solution, we can action it using bespoke Envochem® plant solutions, EnviModul modular plants or Split-O-Mat® SOM compact plants.

Both round or rectangular tanks and lamella plate clarifiers can be used to separate the sludge flocs sedimented from the treated wastewater, depending on the type of wastewater contamination and volume of wastewater.

Our experienced experts also plan and implement subsequent cost-optimised, efficient sludge dewatering and disposal processes for you.

Typical applications for the precipitation/flocculation/sedimentation process:

  • Reliable treatment of wastewater to required limit values (e.g. heavy metals)
  • Wastewater pre-treatment for further cleaning steps through to water recycling
  • Emulsion splitting to separate oils, fats and hydrocarbons
  • Removal of turbidity
  • Removal of precipitable anions (phosphate, sulphate, fluoride)
