Veolia Water Solutions & Technologies' technological expertise covers the full water cycle, sludge recycling and some in-process solutions. Biological stabilization techniques for sludge basically consist of slowing down or even stopping the putrid fermentation that leads to odour pollution.
Sludge Recycling
The biogas can be used as follows:
- incineration in a waste gas burner (required in any case for safety reasons).
- use as fuel in the boiler facility which will enable the digester's temperature to be maintained.
- use as a gas motor fuel following possible desulphurization which will lead to the recuperation of 2 to 2.2 kWh of burnt power/Nm3 and in addition ensure the digester's temperature is maintained.
Water Treatment application
The expertise of Veolia Water in terms of thermal, chemical or biological processes enables it to offer several solutions for sludge treatment.
Water Recycling & Reuse for industries
Veolia Water Solutions & Technologies have proven experience of industrial water production through recycling, in most industries and provide adaptive and high performance technological solutions and associated services in the design, build and commissioning of water treatment plants.
