influence of substrate characteristics
Influence of Substrate Characteristics
  • Maintaining cell vitality and groth of new bacterial sludge
  • Diet of micro-organisms must be supplied
  • Vital nutrients: Carbon, Nitrogen, Phosphorus, Minerals, Trace-Elements
    • Limitation of vital nutrients: stop of metabolic activity
      • Currently controversal discussion about addition of nutrients („wellness-drink“ for microbes)
  • Example: Washing-water of food industry  nutrients + pH regulation necessary
