Introduction
Welcome to QED Environmental Systems’ Skimmer manual.
To ensure the best operator safety and system performance, it is strongly recommended that
the operators read this entire manual before using the system.
This manual reects our many years of experience and includes comments and suggestions
from our sales and service personnel and most importantly from our customers. The chapters,
their contents and sequence were designed with you, the user and installer, in mind. We wrote
this manual so it can be easily understood by users who may not be familiar with systems of
this type or are using a QED system for the rst time.
Safety
Safety has been a cornerstone of our design which has been proven out in building and
shipping systems throughout the world. Our high level of performance is achieved by using
quality components, building in redundancies or backup systems, and not compromising
our commitment to quality manufacturing. The net result is the highest quality and safest
groundwater remediation equipment on the market. We feel so strongly about safety, based
on years of working with the hydrocarbon industry, that it is the rst section in all of our
manuals.

Chapter 1: Safety
Safety has been a prime consideration when designing the Skimmer System. Safety
guidelines are provided in this manual, and the Skimmer System safety features are listed
below. Please do not attempt to circumvent the safety features of this system.
We have also listed some possible hazards involved when applying this system to site
remediation. Nothing will protect you as much as understanding the system, the site at which
it is being used, and the careful handling of all the equipment and uids. If you have any
questions, please contact the QED Service Department for guidance.
As you read through this manual, you will encounter three kinds of warnings. The following
examples indicate how they appear and lists their respective purposes.
Note: Highlights information of interest.
Caution: Highlights ways to avoid damaging equipment.
WARNING: Highlights personal safety issues.
A Partial List of Safety Procedures
These safety procedures should be followed at all times when operating QED equipment on or
off site, and should be considered as warnings:
• Wear safety goggles when working with the Skimmer System to protect eyes from any
splashing.
• Wear chemically resistant rubber gloves, boots, and coveralls when handling the Skimmer
to avoid skin contact with the uid being recovered.

QED Environmental Systems
Skimmer Manual

• Point all hoses away from personnel and equipment when connecting or disconnecting.
• Refer to Chapter # 3: Equipment for a list of parts and hoses supplied with the Passive
Skimmer System.
The Skimmer System minimizes the potential for accidents with the following safeguards:
Fire and Explosion Protection
All QED underground uid extraction systems are either passive or pneumatically driven.
This offers many re and explosion protection features.
• Also, all standard quick-connects are brass, which helps to eliminate sparking hazard.
Spill Protection
On-site spills cannot always be prevented. QED equipment is designed to take into
consideration such unpredictable occurrences that may happen despite strict adherence to
standardized safety practices.
• Down well quick-connects have locking features to prevent accidental disconnections.
• If using a system that pumps hydrocarbon (e.g. AutoGenie, Programable Genie), it is
recommended to use reinforced product hose to reduce the possibility of hose leakage
or kinking.

Revision 1 - December 2007
Chapter 2: Overview
The different types of skimmers manufactured by QED are:
• SOS - Selective Oil Skimmer; 4” well size
• SPG - Specic Gravity Skimmer; 4” or 2” well size
• Bottom - Allows intake as close as posible to the bottom of the well; 4” or 2” well size
Refer to apendix B for specications,
Method of Operation
The Skimmer System is designed to recover free-oating hydrocarbon from any depth. There
are two types of Skimmers: Selective Oil Skimmers (SOS) and Specic Gravity Skimmers
(SPG). The oating intake head on the skimmer follows water table uctuations.
Hydrocarbon rst enters the skimmer through the oating intake head, and then travels down
through exible, yellow tubing to the guide rod. The vaccum generated by any of the QED
product pumps pulls the uid up the guide rod and to the pump.
Refer to the following page for the line of pumps offered by QED.
Alteration of the System
Do not change or modify the system without the express written approval of QED. To meet
the many different needs of users, additional sensors can be added to the system by QED.

Product Pumps
Two types of product pumps can be used for product recovery.
• Programable Genie (PG) - Needs a Controller -For two-inch diameter wells or larger. It
can be used downwell or above ground. It is fully compatible with all the QED skimmer
line and it can remove fuel from as deep as 150 feet. The bladder pump can remove fuel at
a rate of 160 or 320 GPD based on which size (2 or 4 foot) bladder pump is deployed.
• AutoGenie (AG) - Fully Automatic -It requires no surface controller. For two-inch
diameter wells or larger. It can be used downwell or above ground. It is fully compatible
with all the QED skimmer line and it can remove fuel from as deep as 150 feet. The
bladder pump can remove fuel at a rate up to 100 or 320 GPD based on which size (1,
2 or 4 foot) pump is deployed.
Optional Systems/Accessories
Beside the product pumps, the following options are available for QED. Contact one of our
regional ofces for more information.
• Tank Full Shut-Off (TFSO-TM or TFSO-WM) Tank Mount or Well Mount.
• High-Water Shut-Off (HWSO).
• C100M Programable Solar/Electronic Controller
• CTRTFO Tank-Full Shut-Off kit used in combination with the Model C100m

Intake Congurations
Skimmers
QED Environmental Systems manufactures two types of oating intake product
skimmers. The oating intake allows the skimmer to move freely up and down
within the well bore following groundwater level uctuations. The two skimmer
types are: the Selective Oil Skimmer (SOS), and the Specic 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 gures 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.

Page 9
Skimmer Manual
Revision 1 - December 2007
There is a shorter tube section at one end of the selective screen and a
longer section at the other end. When the shorter tube section is placed on
the boom, the product is removed to a sheen. When the longer section is
down, the skimmer leaves a lile more oil in the well. This can enhance
oil movement into the well.
There are two screen sizes available (55 and 110 mesh). The 110 mesh is
standard and shipped with the SOS unless the 55 mesh is requested. The
55 mesh screen is used when more viscous oils (e.g. No. 2 fuel oil) must
be recovered.
The SOS will resist water intrusion up to several inches of water column.
If the SOS is submerged, the hydrostatic water pressure will overcome the
water repulsion ability of the screen and water will enter the skimmer. If
this happens, rinse the green screen in the recovered hydrocarbon to wash
o the water and reinstall the screen into the skimmer.
If the product contains a lot of very small suspended solids or biological
growth, the outer debris screen and perhaps the selective screen on the
skimmer may required periodic service or cleaning.
Caution:
Do not scrub the screen, this could destroy its selective properties.
