Dual Phase Extraction systems are available in two different system configurations. The determining factor behind the selection is the expected operating vacuum level. Liquid ring pumps (oil sealed design) are most suitable for vacuum levels in excess of 15 inches mercury (Hg). Conversely, positive displacement blowers are more suitable for vacuum levels up to 15 inches Hg. Each Dual Phase Extraction system is manufactured to meet your specific requirements.
The Dual Phase Extraction process involves the simultaneous subsurface removal of air, water and product. Hence, there are many other pieces of equipment that are needed to comprise a fully operational system that addresses all phases of contamination.
