Biological Wastewater Treatment

In biological wastewater treatment, micro-organisms metabolise soluble pollutants to produce carbon dioxide, water and more micro-organisms (sludge). To do this, with optimum efficiency, the micro-organisms need a balanced diet that contains the correct ratio of mineral nutrients.

Nutritionally speaking, most wastewaters are unbalanced. To ensure optimal performance from the microbial population their diet needs to be balanced. The most likely macronutrients to be deficient are Nitrogen (N) and Phosphorous (P).

OMEX has developed the highly successful Nutromex range of N&P solutions to deal with these deficiencies and to optimise biological activity and performance in both aerobic and anaerobic Systems.

Key Benefits

  • Optimal COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand) removal.
  • Minimised solids loss.
  • Stable operation.
  • Minimised fluctuations in Nitrogen and Phosphorous outlet.
  • Macro and micro nutrient profiling available.
