Floating Dual-phase Extraction Inlet How It Works |
|
|
Dual-phase extraction (DPE) is the simultaneous recovery of gases and liquids
from the same remediation well without the use of pumps and controls at each
well. High velocity vapor flow entrains the water and allows it to be extracted
from depths beyond the static suction capability of the vacuum source.
With the right site conditions and with the gas and liquid inlets properly
positioned, this can be a highly effective method of contaminant recovery from
both the saturated and vadose zones. However, installation of systems with a
fixed entrainment tube can be complicated and time-consuming, and changing
liquid levels in the remediation well can cause costly downtime and necessitate
frequent site visits for maintenance, increasing both O&M and life cycle
costs.
AutoTracker Floating Extraction Inlets from QED will deliver optimum
performance from your DPE system by continuously and automatically reacting to
changes in well level, positioning gas and liquid inlets properly and allowing
the system to function at peak efficiency at all times. Case studies (see below)
with AutoTracker show that you can:
- Cut O&M costs by 20% instantly
- Clean up your site 33% faster
- Save 1/2 of the life cycle cost.
