Energy solutions for the treatment of wastewater and waste

New regulations and ecological issues have turned the recovery of energy from waste into a major challenge for many local authorities. Treatment infrastructures all over the world produce discharge and sewerage gas. These infrastructures can recover the methane that is produced, instead of destroying or burning it.

Wastewater treatment and purification plants, waste processing centres and landfill sites all use the waste that is contained in wastewater or organic waste to naturally produce biogas, which consists mainly of methane and carbon dioxide. The wastewater and waste treatment plants then capture this gas. The gas can then be used as a renewable fuel to supply electricity to the systems in the wastewater treatment plant, as heat to speed up the sludge digestion process, or can be injected into the gas distribution networks or urban electricity or heating networks. The biogas produced by wastewater or waste treatment plants is contributing to the emergence of local circular economies, in which waste and sludge are used as a source of energy.

Wastewater treatment plants also face the issue of continuity of activity. Power cuts can compromise the wastewater treatment processes, resulting in significant financial impacts and serious environmental damage, such as the discharge of untreated water.

Thanks to our expertise in energy engineering and to our backup electricity systems, you can benefit from solutions adapted to your activity, such as gensets specially configured to run on biogas and backup gensets that guarantee the energy supply of your wastewater treatment plant in the event of a power cut.
