Project Description
This project has entailed the installation of 29 recovery wells within a large building connected to the remediation system via 1 km of pipework suspended from the ceiling. Recovery wells are installed within subsurface well chambers and short trenches provide ducting for the pipeworks.
The remediation system includes Xitech ADJ 1000 smart skimmers for the recovery of floating white spirits (where present in substantial volumes) with low vacuum applied to enhance recovery.
The explosion proof high vacuum extraction system is equipped with a low vacuum and high vacuum header arrangement to facilitate simultaneous low vacuum SVE for the skimmer wells and high vacuum MPE (Bioslurping) in less permeable wells with less product volume
