Intake Configurations
Skimmers
QED Environmental Systems manufactures two types of floating intake product
skimmers. The floating intake allows the skimmer to move freely up and down
within the well bore following groundwater level fluctuations. The two skimmer
types are: the
Selective Oil Skimmer (SOS),
and the
Specific Gravity Skimmer
(SPG).
A
. Selective Oil Skimmer (SOS)
The SOS uses a hydrophobic-oleophlic (selective) screen which repels
water but allows the passage of fuels. Product that enters through the
selective screen is drawn out by the product pump and removed from the
well.
(See figures 2, 3, 4, 5, 6)
The SOS can remove the product layer down to a sheen (< 0.01 inch) if the
product is not too thick or viscous. The product should be about SAE 20
weight or less for good performance.
