| The DEMON® system was initially used for highly concentrated wastewater with the aim of pretreatment (typical efficiency 80 - 90%) and leading the pretreated water back to the main plant. | |
| Meanwhile, the wastewater can also be cleaned up so far, that it can be directly discharged into the receiving water. | |
| Specifically in industrial applications initially the carbon (BOD) is eliminated, and subsequently in a further stage the nitrogen is removed. In the DEMON® system carbon and nitrogen can be eliminated very efficiently and economically in a single process step. | |
| While previous applications were restricted to wastewater concentrations> 500 mg / l, now also low contaminated waste water (> 50 mg N / l) is advantageously treated with the DEMON® system. | |
| An economically lower limit in the nitrogen load and concentration does not exist. | |
| In principle, laboratory tests are done to rule out a possible biological inhibition.In special cases, half-scale tests are carried out. |
