Treatment of micropollutants
For over 10 years, SUEZ has participated in multiple research programmes on micropollutants with its partners (institutions, universities and local authorities etc.) to ensure the suitable condition of aquatic environments. These programmes have resulted in the development of innovative processes and methods to control the whole water cycle: drinking water, urban wastewater, stormwater and industrial water.
Removal of micropollutants in water
These emerging contaminants called “micropollutants” can be found in very low concentrations in the order or a microgram or nanogram per litre. Progress in laboratory testing highlights their growing presence in the aquatic environment and their direct or indirect potentially chronic effects on ecosystems, even at very low concentrations.
Research is ongoing, but efficient treatments are already available to remove micropollution from water.
A solution for each challenge
There are multiple categories of micropollutants, forming two main families:
- Mineral micropollutants such as metals, metalloids and radioactive elements (lead, cadmium, mercury, arsenic, antimony, radon, uranium etc.)
- Organic micropollutants such as pesticides, hydrocarbons, solvents, detergents, cosmetics, medicinal substances etc.
The choice of treatment technology depends on the type of micropollutant that must be removed but also the desired objectives, investment and operating costs. Each technology has its scope of action which varies according to its place in the treatment chain and the properties of the raw water to be treated.
Due to its expertise and wide range of technologies, SUEZ is able to develop the best technical combinations to deliver an optimal solution to each need.
