The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry® units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry® units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from the soil washing process. However, we are able to handle soil contaminated with mercury, hydrocarbons, PAH, PCB, dioxins, furans, organic-lead compounds and many more.
VacuDry® plants for on-site ex-situ remediation projects are delivered in a modular design. This allows easy movement of the system after completion of the remediation job for further use. Because of the negligible process emissions, VacuDry® can be operated safely in a residential area. For temporary projects, we offer a renting solution. Read more in the “Rent a VacuDry®“ section.
