Domestic wastewater characterization by emission source

Why this subject? because of the demand of the society

  • to better reuse nutrients, metals, treated wastewater,…
  • to limit the use of drinking water,
  • to help those who make the choice of dry toilets,
  • to optimize treatment units, also at the scale of a house,
  • …

In France, 20% of the population are concerned by the “on-site treatment”. In this context, we try to answer to 2 questions:

1- What is the characterization of each source of effluent from the human activity? 2- What is the potential of each effluent to be treated by a biological process?

Bibliographic review

Data from

  • Scientific support (treatment of domestic wastewater)
  • Medical characterization on human excreta
  • From the occidental part of Europe (life similar than in France)

~ 100 papers

Datasets are not often detailed. This review is mainly based on averages

Specific attention during the critical reading:

  • Occupation rate of the house.
  • Analysis methods: SS, BOD5, …………………
  • What effluent? new, stored? If stored , how?

Food

1 data

DM = 879 mg/L BOD5 = 756 mg/L

Laundry

1- Qualification and quantification by emission source are not well known (<10 data by each source)

It is necessary to complete the basis by new data. Greywater seem to be very different: food, laundry or personal care

2- Greywater represent a important part of the wastewater

Volume : ~ 70% (and more, if no use of flush water) C (COD, BOD5, SS): ~ 25- 40% P : ~50%

3- Greywater could show some deficiency in nutrients.

Which are the impact of those lacks on the bacterial growth, necessary for their biological treatment? In the aim to answer to the society demand (dry toilets, reuse

  • f nutrients,…), technical adaptations have to be defined. They have also

to be in adequation with the scale of a “house”.
