Hazardous waste treatment solutions for site remediation - Soil and Groundwater - Site Remediation
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.
