Multi / Dual Phase Vacuum Extraction (MPVE)

This highly flexible physical treatment system allows the recovery of free-phase hydrocarbons from the environment, by applying a powerful vacuum to the surface of the groundwater. Sustained application develops a vacuum gradient pulling contamination from the surrounding soil pores to the recovery wells, ensuring maximum recovery with minimal rebound.

Following free-phase hydrocarbons removal, the system may be further optimised to treat contaminated groundwater plumes or be used in conjunction with a chemical injection programme to greatly reduce treatment times and maximise recovery.

Installation using a network of trenches, allows this plant to be installed on live sites, ranging from small petrol filling stations to large industrial plants.
