LONG-TERM SOIL AND GROUNDWATER PROTECTION
The soil filter aeration technology is a development of Finsterwalder Umwelttechnik with the aim of inerting organic landfill ingredients (eg ammonium) or organic impurities in the soil (eg petroleum hydrocarbons).
Our areas of application include the remediation of organically contaminated, complex old sites, old deposits, dumps, landfills, intermediate and final storage. We offer with the FINSTERWALDER soil filter aeration technology:
- automated measurements
- Success control over mass balances
- remote monitoring
- Systemic low energy consumption
- System availability of 98%
- unrestricted use of the surfaces

According to the precautionary principle, Finsterwalder Umwelttechnik’s soil filter aeration technology can be used to carry out the in situ aeration in a pollutant-specific manner and after expansion of the source. This innovative process is characterized by a volume specification of the registered air, pressure measurement at ventilation wells, as well as an analytical determination of the reaction products via the measurement of the pore air composition. Overall, the method offers the possibility of controlling the biological in situ remediation from the beginning and process-specific process parameters
(eg temperature) can thus be adapted.
We are happy to assist you in the area of application and implementation for the in situ stabilization of landfills within the framework of the municipal directive of the national climate protection initiative (NKI). The aerobic in situ stabilization of landfills is a funding priority of the NKI, as former landfill sites are almost exclusively owned by public waste disposal companies. Within the framework of the focus on climate protection concepts, a “Potential study for the reduction of greenhouse gas emissions from municipal waste landfills” can be funded. We would be pleased to prepare a technical potential analysis for the use of suitable technologies to reduce greenhouse gas emissions from landfills that have been shut down (emission potential assessment and preliminary analysis for the technical implementation of suitable methods). In addition, an investment support for the in situ stabilization measure (project-accompanying engineering services during the installation and commissioning phase as well as the use of auxiliary equipment for self-power supply) is provided.
Applications for each calendar year must be submitted by March 31st.
Measuring and automation technology
Finsterwalder soil filter aeration technology completely automates the operation of the ventilation system and the measuring technology. The data is collected daily and can be read remotely from the office at the same time. The faults in the system are also reported automatically and can be eliminated promptly.
The measurements allow the creation of mass balances by the evaluation of the pore air components, separated for the absolute quantities of TN and TC. The course of the substance conversion as a function of time is an indicator of the switch-off time. The measure for this is the increase per unit of time. If this falls below a predetermined limit value, it can be switched off.
