Case: PFAS removal
PFAS removal with surface modified clay in pumped groundwater
Locations: Edegem & Beveren, Belgium
Contamination: PFAS and chlorinated solvents
Flow rate: 20-32 m³/h
Technique: Adsorption on surface modified clay + air stripping
Period: 3-9 months
About this project:
For two construction sites in Edegem and Beveren, Sodecon applied an innovative water treatment method using surface-modified clay to remove PFAS from dewatering water. This technique was selected because of its fast reaction kinetics and better adsorption capacity for certain PFAS components compared to classical adsorbents such as activated carbon.
These projects demonstrate Sodecon’s expertise in innovative, site-specific solutions for the treatment of PFAS-contaminated water.
Edegem – PFAS & solvents
- Flow rate: 32 m³/h
- Duration: 9 months
- Techniques: Adsorption on surface modified clay + air stripping for chlorinated solvents
- Repurposed water: Purified groundwater was used to replenish Fort V’s pond – a great example of circular water use.
Beveren – PFAS treatment during construction works.
- Flow rate: 20 m³/h
- Duration: 3 months
- Techniques: Adsorption on surface modified clay + air stripping
