Microbially active biochar filters for the remediation of CHC-contaminated sites
Abstract
The maB4As project deals with alternative remediation technologies (microbially active biochar filters (MAB)) for the ex-situ groundwater remediation of CHC-contaminated sites. Through the controlled growth of microbial communities on the climate-neutral and resource-saving filter material biochar, the synergy effects of pollutant sorption and microbial pollutant degradation are to be utilised in order to increase filter runtimes, reduce remediation costs and expand the repertoire of remediation technologies. Using the example of chlorinated hydrocarbons (CHCs), a prominent representative of the groundwater contaminants encountered in Austria and worldwide, such a microbially active biochar filter (MAB) is to be planned and investigated in large-scale tests (technical centre, field) for its application in the field. The pilot plant experiment is the essential interface between laboratory and field and serves to optimise the process conditions on a pilot scale in order to make MAB fit for a wide range of hydrogeological conditions and pollutant loads on contaminated sites. Subsequently, the MAB is to go into pilot testing on a CHC contaminated site (integrated into the remediation measures there). The MAB4As project builds on the substantial results of the CHARBAK project. In this project, CHC-sorbing biochars were produced and tested on a laboratory scale in combination with a specially established microbial community with a view to their application in an MAB. The results provided the proof-of-concept for the application of an MAB for complete CHC retention and degradation. Building on this, the MAB4As project aims to bring this remediation technology into practical application so that it can be used as state-of-the-art technology for contaminated sites.
