The soil-washing plant with ReSoil technology was constructed in city of Prevalje which sits in a contaminated area of Meža Valley, Slovenia. The mission of this facility is to prove the scalability of ReSoil technology. With the capacity of 6 t/day it enables demonstrational remediation of local sites as well as demonstration of ReSoil technology to stakeholders. The Technology Readiness Level of plant operation is TRL 7 (EU, NASA methodology).
The permit for construction of this soil washing plant was granted by Slovenian Environmental Protection Agency in 2017. The permit was based on proofs of ReSoil closed process cycles operation and zero-emissions. Construction of the plant was co-financed from EU LIFE + Programme with 50% contribution of 1.1 M EUR. The operating permit for this soil-washing plant was obtained in July 2018. The ReSoil technology uses common process equipment such are sieves, mixing vessels and filter presses. The remediation process can be controlled manually and the innovative part of ReSoil technology, i.e. in press soil rinsing, EDTA and process water recycling, can also be controlled automatically by the SCADA (supervisory, control and data acquisition) system.
