Innovative steps on water mitigation on the airfield will build a better
environment on the airfield.
EDMONTON INTERNATIONAL Airport (YEG) is testing
a new filtration system to release clean water back
into the local ecosystem.
Edmonton uses about 4 million liters
of deicing fluid each year. The airport is
utilizing a new portable filtration system
for its stormwater ponds to remove the
fluid from stormwater runoff.
Steve Maybee, vice president of
operations for YEG, said the initiative
started when airport leaders wanted
to tackle challenges with deicing f luid.
As the airport continued growing in
recent years, there was a concern current
retention ponds weren't big enough to
address runoff issues.
Edmonton wanted a solution without
a major capital cost. Given its history
of innovation, they took a chance at a
technology new to the aviation industry.
"We didn't want to build more ponds
because that can create a bird issue," he
said. "We want to find an alternative
solution than having storage ponds all
over the airfield."
The Swirltex filtration technology
allows YEG to be able to release clean
and filtered water back into the local
Whitemud Creek. Suspended solids, oil
and other contaminants are channeled
away from the membrane surface,
reducing fouling, allowing more clean
water to pass through the membrane
pores, resulting in clean, consistent
quality water.

Peter Christou, president of Swirltex,
said ceramic membranes stain when
used with oil/water separation. Swirltex
spins the water in the tube to create a
centrifugal force in order to draw the
oil to the center so it doesn't come into
contact with the membrane.
Christou said when adding air into
the process during wastewater treatment,
they can manipulate the buoyancy of
other contaminants, so they also don't
have contact with the membrane.
Swirltex was using its product to help
rural communities filter wastewater using
a portable product. When Edmonton
called to try it at the airport, it allowed
Swirltex to use the product in a similar
manner.
One Swirltex unit can filter about
3,000 cubic meters per day.
"A lot of the engineering costs and
infrastructure costs that are normally in
an airport job was gone," Christou said.
"It was very easy to just put a unit down
there, operate it and get the results it's
looking for."
Maybee said the Swirltex filtration
unit is already being used in the oil and
gas industry so the airport wanted to
try it for a similar usage at their facility.
They decided for the test run in April.
If the results pan out, the airport will

determine if it will incorporate it into
their daily operations.
"You can only build ponds so big
before you need to look at other ways
of dealing with fluid," he said.
The technology can also reduce
EIA's future need to build larger water
treatment facilities.
Christou said the system would also
benefit airports in direct glycol recovery.
The membrane would make it beneficial
in that application.
Christou said airports determine
their strategy for wastewater treatment
and determine if they want to make a
comprehensive plan to treat glycol water
not as waste, but a resource.
"The membranes we use are the same
pore size they use for drinking water,"
Christou said. "So we can get the water
or glycol to extremely high purities with
extremely low energy."
