The problem


The limnological conditions found in our lakes, dams and ponds are frequently characterised by the excessive introduction of nutrients and harmful substances. This results in eutrophication within the water and the subsequent formation of sapropel.
During the summer months, very heterotrophic bodies of water often have oxygen concentrations of < 0.5 mg/l at a depth of about 0.5 m.
As the depth of the water increases, an oxygen content of almost zero is reached.
Because of these anaerobic conditions, putrefaction processes are found to prevail in the water at times. Digester gases such as hydrogen sulphide and other harmful substances are released as a result of this.
Health risks, unpleasant smells, fish deaths and restrictions on use as drinking water are the result.


The solution


Depending on the state, size and use of the water, HERBST UMWELTTECHNIK GMBH provides various water sanitation processes.


The most important sanitation processes are:


  • Mechanical sanitation processes


During these processes, the digested sludge is sucked off and mechanically dewatered and the resultant water, which is rich in harmful substances, is purified.

  • Chemical/biological processes


During these processes, nutrients and hydrogen sulphide are adsorptively bound and then biologically decomposed.


  • Combined processes


These processes combine various sanitation processes like Saniromat or Sediturtle.
