Sludge recycling: make better use of your resources
The treatment of domestic wastewater is a central issue for public safety and the environment. Sludge treatment processes avoid risks to the environment and respect the water cycle.
Yesterday's constraints are today's opportunities: sludge naturally generated by wastewater treatment can be a valuable asset. We support our clients to manage biosolids: an economic issue as well as an environmental issue
Discover how you can reuse, recycle and leverage value from wastewater, such as converting sludge into biogas.
Combined sewer overflow (CSO) may contain particulate and soluble wastes from domestic sewage, industrial and commercial wastewaters. These waste products include suspended solids, bacteria, viruses, nutrients, toxic pollutants, oil, grease and debris, posing significant risks to receiving water quality, public health and aquatic life.
We provide municipalities and industries with solutions to control and limit sewage overflows which are toxic for the environment.
Our patented Actiflo® process is particularly well suited for high-rate clarification and removal of total suspended solids and biochemical oxygen demand during wet weather conditions. Its performance for the treatment of discharges in rainy weather has been demonstrated in numerous installations around the world.
Veolia Water Technologies has vast experience within soil and groundwater remediation. Today, more than 100 customers in 10 countries benefit from our technologies, improving the quality of water and avoiding contamination.

Per and Polyfluorinated-Alkyl Substances (PFAS) are a class of anthropogenic chemicals containing fluorinated carbons with a charged functional group (carboxylic acid or sulfonic acid) that are resistant to degradation.
We offer a wide range of PFAS treatment and management services for the following:
- Surface water
- Landfill leachate
- Industrial discharges
We also contribute to the community by fostering local employment and by being an engaged corporate citizen. For example, we support socially responsible businesses and encourage greater water awareness.
Municipalities that trust Veolia
Energy-positive wastewater treatment plant
Veolia Water Technologies’ subsidiary OTV began working on the Cagnes-sur-Mer wastewater station in 2017.
Beyond the architectural concerns regarding the design and harmony of the building in the sector and the green aspects integrated in the plant, OTV accomplished France’s first energy-positive wastewater treatment plant with high-performance equipment in compliance with European standards.
Today the plant treats the wastewater of 160,000 inhabitants and produces more energy than it consumes.

FAQ about water solutions for municipalities
How is water treated to make it potable?
Different types of treatment are available depending on the quality and origin of the raw water:
- Surface water treatment generally includes at least filtration to remove suspended solids followed by disinfection to eliminate various pathogens such as parasites and viruses. The water may need to be clarified upstream of filtration if the solids concentration is high or varies too much, or contains other pollutants such as organic matter.
- Groundwater containing metals may require oxidation followed by filtration.
- Seawater, in addition to the clarification and filtration steps, will require treatment with reverse osmosis to remove salts and dissolved compounds.
- Emerging compounds (pharmaceuticals, micropollutants, etc.), pesticides, PFAS/PFOS, require advanced treatments – adsorption for example.
What are the different steps for municipal wastewater treatment?
Municipal wastewater first undergoes screening to remove coarse solids and floating materials. Sand and grease are then removed to protect downstream equipment. Primary treatment, including settling or filtration, will remove most of the solids. The treated water is then sent to a biological treatment stage, which will attack the dissolved organic pollutants, carbon, nitrogen and phosphorus. A tertiary treatment step can then be applied to refine the removal of the remaining solids and phosphorus and, depending on the regulations in force, emerging micropollutants (pharmaceuticals, hormones, etc.). Finally, the water is disinfected, often using ultraviolet radiation systems.
The sludge generated by the various wastewater treatment steps is sent to the sludge treatment chain for recovery and valorization.
How can wastewater be reused?
In a context of water scarcity exacerbated by climate change, water reuse is becoming a necessity. Wastewater can be reused for many purposes such as irrigation, both in an urban context (golf courses, parks, etc.) and in agriculture, groundwater recharge, industrial use, and even drinking water production.
There is no specific technology allowing the reuse of water: water reuse is generally carried out by combining several processes or technologies depending on the case, such as biological or physico-chemical treatment, clarification, gravity and/or membrane filtration, evaporation and disinfection.
How is sewage sludge treated?
Depending on the local economic and regulatory context, different processes can be used to treat sewage sludge. Generally, the sludge is first decanted and thickened in order to remove water and reduce its volume. A subsequent digestion step allows additional reduction in volume by applying an anaerobic biological treatment. This step produces biogas which will then be purified in order to allow its injection into the natural gas network in the form of renewable energy. The solid waste from the digester, the digestate, can be dried for incorporation into compost intended for agricultural land application, thereby returning the carbon to the soil. It can also be thermally oxidized, which generates green electricity and inert ash with different potential uses, as road foundation for example.
