On-site Soil Washing

Mobile treatment of soil, dredged sediments and PFAS-contaminated materials

Mobile soil washing throughout Europe

Kurstjens specializes in mobile soil washing, using fully on-site installations. We treat contaminated soil streams directly at the project location, significantly reducing transport costs, project lead time, and environmental impact.

Our installations are deployable across Europe and can be fully operational at your site within four weeks.

We treat, among others:

  • Contaminated soil

  • Dredged sediments

  • Sewer, gully and pumping station sludge (RKG)

  • Sweeping sand and screened sand

  • Mineral sand and sludge mixtures

How does soil washing work?

Our process is based on wet mechanical separation (particle size and density separation). By leveraging the physical properties of materials and contaminants, we separate valuable fractions from residual waste streams.

We integrate advanced technologies such as:

  • Screening units

  • Log washers

  • Hydrocyclones

  • Spiral separators

  • Upflow classifiers

  • Magnetic separators

  • Organic matter separation

This integrated approach enables high-quality reuse of sand and aggregate fractions, with maximum removal of contaminants.
