UET’s Single Phase Extraction systems (ProVac) remove spilled LNAPLs and DNAPLs, from subsurface formations without the pumping of groundwater. These systems use high vacuum forces similar to DPE/MPE systems to mobilize the spilled contaminant liquids contained in the saturated zone. Single Phase Extraction is a lower cost solution for the recovery of free product at your site. Unlike Dual Phase or Multi-Phase Extraction, Single Phase Extraction does not require any pumping, separation, treatment or disposal/discharge of treated groundwater. Most importantly, UET’s SPE systems, designed to mobilize and recover spilled product,do not waste energy and can result in an earlier site closure and a cost savings of up to 50%. The Single Phase Extraction System can be configured as a single well portable or in-situ (built-in) multi-well system depending on your site’s specific needs.
