Test plant for groundwater remediation with 100 percent renewable energy supply, Bavaria. It also works without an aggregate or conventional power supply: Long-term pumping tests are being carried out on a former lamprophyre quarry, where mineral oils, metal waste, sewage sludge and hazardous waste such as metal sludge were stored between 1945 and 1970, as a pilot test for a potential future safety measure, with energy being supplied via PV modules and a power storage unit.

Pumping tests and remediation investigations for the purification of contaminated water. We offer various mobile test plants for pump tests and remediation tests for the purification of contaminated water (PFAS, organic pollutants, heavy metals). These can be used to test various sorption materials with regard to purification performance and service life. The systems have different tank sizes and are designed for flow rates of approx. 0.15 - 0.3 m³/h, 1 m³/h and 5 - 36 m³/h.

In-situ remediation with electric heating elements for cleaning soil contaminated with VCHCs. In-situ thermal remediation (ISTR) of an VCHC contamination on the site of a former chemical cleaning facility using fixed, electrically operated heat sources and soil vapor extraction. The subsoil has a very inhomogeneous structure and low permeability. The VCHCs were located in the unsaturated soil layer at a depth of up to 15 m below ground level. The heating of the soil body and the extraction of the CHCs took place over an area of approx. 1,000 m². The outflow was hydraulically secured with the aid of a groundwater treatment plant. The remediation was successfully completed and the remediation objectives were achieved.
