Two Teacher Institutes Set for 2005
Safety in the Air
The Minnesota Section American Water Works
Association (AWWA) and Minnesota Department of Health
(MDH) are planning on holding two Drinking Water
Institutes for teachers in the summer of 2005. Conducted
with the participation of the Science Museum of Minnesota,
the Institute consists of a three-day workshop in which middleschool science teachers from around the state learn about
water supply and treatment as well as how to teach the
subject in their classrooms. The teachers, who receive two
graduate credits for their participation, develop action plans
for incorporating inquiry-based activities on water into their
existing curriculum and return for a follow-up session this fall
to present their plans.
One Institute has been conducted a year starting in 2001,
but this year Minnesota AWWA and MDH have scheduled
two Institutes. They are planned for June 20-22 at St. Paul
Regional Water Services and June 27-29 in Detroit Lakes.
Each Institute can accommodate a maximum of 24
teachers. At least 16 teachers must sign up by the end of
April or the site will be cancelled. The Institute is free for
teachers.
Teachers can get register via e-mail at [email protected]
or by calling 651-221-4747. On-line registration is also
available at http://www.smm.org/educationprograms/
schoolsandeducators/register.php.

Inside:
By Bill Anderl, Minnesota AWWA Safety Committee Chair
Work in and outside of water
towers can be hazardous, as indicated
by two fatalities in Minnesota in the last
few years. One occurred in August of
2004 as a worker fell to his death when
scaffolding apparently collapsed while
he and two others were working on the
outside of a water tower.
Two years before that, a water
operator in another community was
working inside an empty water tower tank, where he had
cleaned an accumulation of sludge off the bottom of the tank.
As he climbed out of the tank, he likely slipped off the ladder
and fell back into the tank. Working without a full-body
harness and retractable lifeline, the operator did not survive
the fall.
Before any work is done on a water tower or other water
storage reservoir, all safety hazards associated with them
should be identified and addressed. Workers must have
adequate training in fall-protection and confined-space entry.
Fall-protection equipment must be used properly, and rescue
planning must be done for each location and work task.
Recently, an incident on a water tower in North Carolina
had a happier ending as a worker suffered a heart attack
atop a tower, causing a fall that left him dangling on a rope
150 feet above the ground. Fortunately, his brother was working with him on the tower and was able to call for help. The
responding local fire department and county tactical squad
came to the scene and performed what’s known as a highangle rescue. The worker was lowered to the ground safely
and airlifted to a regional medical center for treatment.
This rescue was successful because the response team
was well trained and prepared. The high-angle rescue is
practiced annually on area water towers. According to the
team leader, the preparation really paid off.
This year, the Minnesota AWWA Safety Committee will
be promoting fall-protection programs and rescue planning.
Watch for more information soon.

Minneapolis Ready for Ultrafiltration
The first significant
phase in a decade-long
process to upgrade
Minneapolis Water
Works and position the
utility to meet emerging
threats and more
stringent standards is
nearing completion. An
ultrafiltration (UF)
membrane plant at the
system’s facility in
Columbia Heights will be
on-line this summer.
Capable of producing
up to 78 million gallons
per day (MGD) during
the warm-weather months,
it will be the largest
ultrafiltration system for
drinking water in the United States and will enable
Minneapolis to comply with increasingly tighter limits for
microbial removal. In addition, the selected membrane
system provides for removal of viruses and may deal with
emerging microbes. The plant is set up to allow for future
enhancements that could address endocrine disruptors.
In the wake of the Cryptosporidium outbreak that had
occurred in Milwaukee in the spring of 1993, Minneapolis
Water Works commissioned a feasibility study. “We looked
at all of the available technologies to address our risks, which
were based on log removal [percentage] needed,” said Adam
Kramer, Director of Minneapolis Water Works. “The study
included investigating ozone, UV [ultra-violet treatment],
membranes, and a conventional plant. We viewed the risk in
the source water, the log removal needed, determined the
available removal from our existing facilities, determined the
gap, looked at the treatment that would fill the gap, and then
looked at the age of the infrastructure.”
From this analysis, along with the desire to retain soft
water, the decision was made to go with membrane
filtration. The upgrade will take place by constructing a new
membrane ultrafiltration plant to replace the granular media
filters at the Columbia Heights filtration plant and
construction of a water treatment residuals lagoon. The
overall cost of the project is $56 million, with the membrane
system representing $16 million of it.
“We were postured in a perfect position to put in new
technology,” Kramer added. “Experts from multiple national
consulting firms concurred with that recommendation.
“If you’re going to something new, do you put in old
technology or new? That’s what it boils down to.”
Minneapolis Water Works gets its water from the
Mississippi River in Fridley, where it has both a filtration plant
and a softening plant. Another filtration plant, built in phases
from 1913 to 1918, is in Columbia Heights, approximately
two miles away. Water from the river enters the softening
plant and then goes to the filtration plants in Fridley or
Columbia Heights. Some of the Fridley water goes straight
into the distribution
system. The rest goes to
a reservoir in Columbia
Heights and is mixed
with the water there.
Eventually, an ultrafiltration plant similar to
the one now being built
in Columbia Heights
will be constructed in
Fridley.
The existing filter plant
in Columbia Heights,
which uses ferric chloride
as a coagulant with
chlorine and ammonia
added to the water, will
serve as pretreatment
for the ultrafiltration
membrane system.
Membrane Options
Membrane filtration, which removes particles too small
for conventional filters to remove, started in the 1960s with
reverse-osmosis (RO) membranes for desalination. Since
then, a range of less discerning membrane filters—
nanofiltration, ultrafiltration, and microfiltration—became
available, and these, along with RO, were the choices
available to Minnesota.
Some of the advantages of reverse osmosis and
nanofiltration, such as dissolved-solids reduction, weren’t
needed by Minneapolis. Reverse osmosis would provide
softened water, but since the utility already has a softening
plant with a useful life remaining, it wasn’t considered
necessary. Nanofiltration would have created problems with
a large amount of wastewater, so the decision came down to
microfiltration and ultrafiltration. Minneapolis, with its Peer
Review Panel and Citizens Advisory Committee, opted for
the latter, with emerging microbes and their size being the
deciding factor.
“Cryptosporidium and Giardia are two to five microns.
We were looking at the emerging microbes that are
much smaller than that,” explained Kramer, who said they
used surrogate viruses to determine pore size. “We
specified and tested for a minimum of 4-log removal,
which established the pore size, and that pointed to
ultrafiltration.”
Kramer added that reverse osmosis remains an option
for the future and one that likely will be employed if there is
a problem with endocrine disruptors and pharmaceutical
products, which enter the wastewater system and ultimately
water sources, such as rivers, through excretion from
humans. “We have, at the Columbia Heights plant, the
piping and a place to have the UF become pre-treatment
for the RO,” he said, “which would allow us to convert from
an end-of-treatment to a pre-treatment for endocrine
disruptors.” If and when this happens in both Columbia
Heights and Fridley, Minneapolis will get rid of its softening
facility.

Ultrafiltration Process
Many membrane systems use crossflow
filtration, in which feed streams flow across the
membrane rather than through it, as is the case
with conventional filtration. With crossflow, the
suspension to be filtered is pumped along the
membrane surface to avoid fouling, and only a
small portion of the stream is filtered through the
membrane. However, energy consumption was
a major concern with crossflow systems; as a
result, a more energy-efficient concept, called
dead end or semi-dead end, was developed. A
dead-end system essentially operates like a
coffee filter, eliminating all solids in suspension
and retaining them on the membrane surface.
Periodic backwashing removes those solids from
the membrane surface. Once or twice a day, the
membranes are exposed to a brief soak with
chemicals present, called a chemically enhanced
backwash, to keep the membranes clean.
“Crossflow would have some part of the stream
continue past the membranes instead of a quasi
dead-end system, which forces the stream through
the permeable membrane, with that being the
barrier to larger particles, including pathogens”
explained Madalyn Epple, a regional sales
manager for Ionics, which is responsible for the
complete membrane system being installed at the
Columbia Heights facility.
The ultrafiltration technology will use an Ionics
UF membrane system containing more than 4,000
Norit X-Flow hydrophilic capillary (hollow-fiber)
eight-inch diameter membrane elements. Dale
Folen, the project engineer for Minneapolis
Water Works, said the treatment process will
consist of four trains with 10 units in each train.
Each unit has 28 pressure vessels with four
hollow-fiber modules inside each pressure
vessel. “Water comes from feed pumps to the
units,” he said. “The permeate, or treated water,
goes down the train to the opposite end. All units
in the train operate in parallel. The water goes
through the membrane and then becomes
permeate, exiting through a separate line. It
operates in dead-end mode; the flow goes from
the inside of the hollow fiber to the outside.”
“It’s an inside-out operation,” says Epple,
noting that the stream is forced into the inside of
the fiber from both ends of the membrane. “It
then permeates through because the water
molecules are small.
Pathogens like
Cryptosporidium, Giardia, and viruses are
much larger than the pores of the membrane.
Water passes through easily and anything larger
than the pores of the membrane stays on the surface of the membrane until they are backwashed
and the solids are removed from the system. All
of this takes place at low pressure with an average net driving pressure of 5-10 psi [pounds per
square inch].”
Epple added that a spiral-wound system, unlike hollow fiber, cannot be
backwashed. “And it’s crucial in this industry to have that positive
barrier to be able to verify the integrity of the system,” she said, referring
to the ability to confirm that all fibers are intact.
Folen said that the units are taken out of service if the fiber is broken.
“The plant is sized so that 36 units [of the 40 units] can meet 78 MGD,
which is their design, so they can still meet full capacity even with some
of the units taken out of service. A diffused-air test is used to monitor
and confirm the integrity of the system.”
Backwashing occurs every 25 minutes and takes 45 seconds,
according to Folen. “Backwash water, which is UF permeate, forces
water in the reverse direction from the outside of the fiber to the inside,”
he said. “Two trains can be backwashed simultaneously. The
feed-pump system is set to a common pressure on the upstream end.
Each unit does throttling and flow control depending on how dirty each
unit is.”
For post-treatment, fluoride, chlorine, ammonia, and polyphosphate (for
corrosion control) will be added.
Security
The plant will be constructed to meet the sometimes conflicting
objectives of maintaining security while being accommodating to visitors.
“With ultrafiltration a new technology, there will be a lot of people
wanting to know about it,” said Folen, adding that they expect visitors
from around the world. The facility will have a meeting room as well as
displays of an ultrafiltration module and a teaching/learning area for tours.
Closed-circuit cameras and televisions will also be available.
“For security reasons, we don’t want visitors to see the complete
layout,” said Kramer. “If they want to see what the chemical storage
room looks like, we bring it up on the screen. They can look through
windows to see the plant, but we don’t want them to see the
configuration.”
Adolfson & Peterson Construction of Minneapolis is the general
contractor. Pioneer Power of St. Paul is the mechanical contractor. The
electrical contractor is Gephart Electric of St. Paul. Black & Veatch
Corporation of Minneapolis and Kansas City designed the plant. The
team of HDR Engineering, Inc. of Minneapolis; Malcolm Pirnie, Inc. of
Cleveland; and Separation Processes, Inc. of San Marcos, California
assisted Minneapolis with the procurement of the ultrafiltration
membrane equipment.
A retaining wall in front of the new ultrafiltration plant consists of
cobblestones from early streets in Minneapolis.

At the end of the Florida Keys—approximately 70 miles to the
west of Key West, the terminus of U. S. Hwy. 1—is a cluster of
small islands known as the Dry Tortugas. Discovered by Ponce de
Leon in 1513, they were first named Las Tortugas due to the
abundance of sea turtles. The word “Dry” was soon added to
mariners’ charts to warn of the lack of fresh water.
The Tortugas were fortified in the mid-1800s with the
construction of Fort Jefferson, which also became a military
prison for captured deserters as well as four men convicted of
complicity in the assassination of Abraham Lincoln. The
prisoners included Samuel Mudd, the doctor who treated John Wilkes
Booth, Lincoln’s assassin.
For water supply in the fort, engineers devised a system to
collect rain water and pass it through sand filters on its way to the
more than 100 cisterns in the fort. The cisterns had a capacity of
1.5 million gallons. As the fort foundations settled, however, sea
water leaked in, making the water undrinkable. With over 1,200
people here during some of the Civil War years, the Army secured
two steam condensers capable of distilling 7,000 gallons per day
from sea water—if fuel arrived from the mainland.
Today, visitors to the Tortugas must bring their own water. As
for waste, the key has some recycling toilets that use no
water or chemicals. The waste is composted in equipment below
the outhouse building. However, when the ferry from Key West is
docked at the Tortugas, from approximately 11 a.m. to 2:30 p.m.
each day, people use the facilities on the ferry. The toilets on the
Tortugas are used only by campers, National Park staff, and those
arriving by plane outside of the hours that the ferry is docked.
Fort Jefferson, which occupies 11 of the 16 acres of the key it is on, is
surrounded by a moat. The island itself has no fresh water.

Safe Drinking Water Act Turns 30
December 16, 2004 marked the 30th anniversary of the
passage of the federal Safe Drinking Water Act, which, for
the first time, established a national program of standards and
regulations for drinking water. “The Act has been at the core
of our progress as a nation in improving the quality of drinking
water and the health of our citizens,” said Jeff Stuck,
president of the Association of State Drinking Water
Administrators (ASDWA). “This historic day is an appropriate time to reflect on
the accomplishments of the past 30 years, the states’ role in the implementation of
the Safe Drinking Water Act and the challenges that still lie ahead.”
ASDWA pointed out that the number of contaminants regulated by public water
systems has grown from about two dozen in 1974 to nearly 100 in 2004, while the
number of waterborne disease outbreaks has dropped and continued to stay low.
Today, more than 273 million people receive water from 53,000 community water
systems. The vast majority of that water meets all public health standards.
