Sustainable technologies for the remediation of contaminated sites

Trireme is an innovative start-up for the remediation of contaminated sites. It was born from the union between Researchers of the Chemistry Department of the University of Rome "La Sapienza" and the Water Research Institute of the National Council of Research (IRSA-CNR) with Edison NEXT Society. It offers highly specialized services to help the client in all phases of the remediation of a polluted site.

The decades of expertise developed in the research are applied by Trireme in supporting its customers in constructing solid conceptual models as an indispensable basis for designing the most appropriate decontamination interventions – with specific care to environmental, social and economic sustainability.

  • TECHNOLOGY

    From the knowledge of the most advanced technologies for the characterization and remediation of polluted sites comes the ability to identify the most appropriate solution for each contaminated site, including the most complex ones with historical contamination.

  • INNOVATION

    Innovation is the key to selecting and developing advanced remediation technologies and building the best strategy for the complete restoration of polluted sites in terms of environmental, social and economic sustainability.

  • MULTIDISCIPLINARITY

    The most effective solutions for managing and restoring a contaminated site are based on a multidisciplinary approach where chemical, biological, geological, engineering and procedural skills are fully integrated.

THE PATENT

Trireme is acquiring the exclusive rights of a patent concerning the remediation of complex sites historically contaminated by chlorinated solvents, nitrates and sulphates, the inventors of which are the founding members and the industrial partner.

The patent was jointly filed with the German IEG technolgie GmbH which supplies the Groundwater Circulation Wells as an essential technological component of the process.

Innovative

It uses the advantageous coupling of the hydraulic manipulation of the aquifer with GCW-IEG wells with the stimulation of biological reductive dechlorination in situ by fermentation of a biodegradable polymer obtainable from organic waste degradation. The process takes place without net water extraction.

Applicable

The process is potentially applicable in all aquifers contaminated by chlorinated solvents in which there is a minimum natural dechlorinating activity and is above all aimed at the elimination and containment of active secondary sources, in particular for situations of historical contamination.

Tested

The patent has already been extensively tested at the pilot scale with excellent results and for two years has been applied at full scale in an important industrial site active on the national territory, included in an Operational Safety Implementation procedure.

Sustainable

The process does not generate waste water, uses a biodegradable polymer and minimizes the production of waste. Reduces the mass of contaminants in the source and at the same time hydraulically controls and significantly reduces the mass flow of contaminants to external areas
