Column Treatability Services
Column studies can be used in instances where the treatment effectiveness cannot be accurately evaluated in a batch test or when higher confidence levels are required to produce scalable results. Column testing provides insight into how groundwater flow rates and residence times may impact the outcomes for several remedial technologies and applications such as permeable reactive barriers (PRBs). Site geochemical and biological conditions (e.g., air/oxygen supply [or other gasses such as methane]) can also be maintained in columns to simulate site conditions as closely as possible.
Loureiro has experience in conducting column testing for the following technologies:
- In situ chemical oxidation (ISCO)
- In situ chemical reduction (ISCR) using zero valent iron (ZVI)
- Stabilization/sorption
- Soil vapor extraction (SVE)
- Thermally-enhanced SVE and biosparging
- Surfactant-enhancements
- Wastewater treatment
In-house readings allow us to assess the progress of the column studies to optimize treatment parameters for incorporation into a full-scale implementation. We produce scalable results for incorporation into the design of a field application.
