  • Patent number: 5529121
    Abstract: A process for contaminant removal from the ground or ground water involves employing a simple "dry" vacuum device (100) to apply a vacuum to a conventional well (60) for the recovery and separation of vapor contaminants, "free product", and contaminated water. The process employs a staged separation system for separation of the liquid phases, removal of contaminants from water, and vapor separation. The staged separation system allows the use of an "off the shelf" centrifugal (26) pump for effluent discharge. The process introduces additional dispersed air bubbles into the contaminated water which will aid in removal of contaminants. The process alternately employs a hydrophobic filter (56) to recover large amounts of "free product".
