HEISTT High Efficiency In Situ Treatment Technology
| Country: International organisation- network or project
| Start Date:
Project Type: RTD
| Contract Number:
| Organisation Type:
Contaminated land-->Remediation options-->In situ treatment technologies
| Project objectives:
The idea for the HEISTT concept derives from the quick installation of multiple band drains which could similarly be deployed to include chemical treatment
for the remediation of polluted groundwater plumes. Chemical treatment (such as oxidation and reduction technologies) is an established and successful
remediation technology, nevertheless at individual sites it can become financially uncompetitive treatment option when specialist rig and relatively
slow rates of drilling mean high installation costs. The HEISTT concept looks at providing proof of concept and early prototype for a unique rig which can be
adapted to be mounted off a standard excavator arm, and rapidly installs chemical treatments into the subsurface. The increased installation rate, depth
of hole and cost could create savings enabling the technology to become both more widely accessible in terms of people able to use the technology and spectrum
of sites which would become cost effective for treatment using the HEISTT system.
What it is going to do?
The proposed HEISTT system represents a step change over existing in situ chemical deployment technologies with the potential to deliver:
◦Order of magnitude improvement in speed of remediation treatment chemical installation. Installation of 5 boreholes a day may be typical under
conventional methods whilst up to 100 boreholes per day are proposed through the HEISTT system.
◦Reduced remedial treatment costs through more efficient use of treatment chemicals
◦Simpler and safer installation of remedial treatment chemicals
◦An increased rate of remediation through better distribution of treatment chemicals
HEISTT is a collaborative research project developing an innovative system for the application of remedial chemicals into soil subsurfaces for the purpose
of contaminated groundwater treatment.
The technology being will improve treatment application times and facilitate highly efficient remediation. The improved cost efficiencies for this type
of treatment will reduce barriers for access allowing a broader use for these types of treatment.
