Calgon Awarded $6.5 M Contract for
Perchlorate Removal
PITTSBURGH, April 12 /PRNewswire-FirstCall/
-- Calgon Carbon Corporation (NYSE: CCC) announced today that it has
received a contract from California Domestic Water Co. in Southern
California to remove and destroy perchlorate from groundwater using
Calgon Carbon's ion exchange technology, including its emergency
perchlorate service equipment and proprietary ion exchange resin.
The contract is valued at $6.5 million.
The project is scheduled for
completion in the second quarter of 2002. The Calgon Carbon ion
exchange systems will treat approximately seven million gallons of
water per day and provide safe drinking water for 120,000 people in
five communities in Southern California.
Commenting on the contract, Jim
Byerrum, president of California Domestic said, "When
perchlorate was identified at the California Domestic wells, the
first company I called was Calgon Carbon. Their response was
immediate, and within five weeks of contract execution I had
equipment arriving at my site."
Bob O'Brien, senior vice president of
Calgon Carbon, said, "We are pleased that California Domestic
Water Co. chose Calgon Carbon's leading-edge technology to protect
its customers from perchlorate contamination. To date, we have
received six contracts for perchlorate removal, including four from
water utilities to restore water to drinking water quality. When
this project is completed, our ion exchange technology will remove
perchlorate from more than 35 million gallons of drinking water per
day."
Calgon Carbon Corporation ( http://www.calgoncarbon.com/
), headquartered in Pittsburgh, Pennsylvania, is a global leader in
service and solutions for purifying air and water. The company
employs approximately 1,000 persons at 13 operating facilities and
11 sales and service centers worldwide.
"I
was impressed.."
"Black
Box" Screening System Solves Odor Problem
The Headworks' Black Box,
self-contained screening system, was installed at the Treaschwig
wastewater facility recently, replacing an old, manual screen.
This
unique system combines super fine screen openings of 3/16-inch (4mm)
with the ruggedness of a bar screen, to provide high cleaning
capacity. This particular system also contains a Transpactor. The
decision to go with an entirely enclosed system solved a critical
odor problem while satisfying the demanding engineering requirements
of the search committee.
"Our original intent was to use
a rotating fine screen," said Ken Hudson, president of the
Treaschwig Joint Powers Board. "But the cost was prohibitive.
We would have had to build a structure at least six feet higher than
what was there and then go back to all seven of the contributing
pump stations to modify the existing pumps." Hudson added that
they "would most likely have had to build a containment area as
well" which they did not have to do with the Headworks Black
Box system.
Hudson talked about the long search
for the right system. "I was impressed with the Headworks
screen already installed in The Woodlands. Fact is, the Headworks
screen was the best piece of equipment they had there," he
said.
The Treaschwig facility serves about
3,500 households in Timberlane, Birnam Wood, Post Wood and Green
Gate in Houston, Texas.

Program, municipalities can experience the EMU submersible mixer
technology at their own facility, prior to purchase.
“When
plant operators or engineers experience the EMU submersible mixer
‘first-hand’ they almost always want to make the switch to this
advanced mixing technology,” explains Terry Rouse, general manager
of EMU Products for USFilter. “That’s why we decided to offer a
comprehensive trial program. This technology virtually sells itself.”

Test-In-Your-Tank Trial Program, contact USFilter at (800) 841-1550

Mr. Virden needs help with
package plants:
I work for a county
school system and recently received my license to operate our 3
package plants. The guys that operated them before me never wasted
any sludge. They would scrape the plant, add chlorine, and of
course, shovel off the sand beds all the time since they had sludge
flowing over the weirs.
The class I took did
not go into exact wasting procedures. I have a book with a few
different ways of figuring wasting amounts, some of which are quite
complicated. Does anyone out there have a way that works well for
them?
The formulas I have
are for maintaining a certain sludge age, but none of them describe
a way of REDUCING the age. I believed that I was wasting enough,
but, I ended up with too much in the sludge that is too old. I had
the truck come and pump them down, but through my lack of knowledge,
they are starting to get ahead of me again. I would appreciate
any info.

I am working on finding a suitable
separating system for an emulsified oil/water mixture. I want to
reduce oil concentration in water from 300 ppm to 20 ppm. I
understand that dissolved air flotation systems and RO systems are
capable of giving me the desired results.
However, I have also come across
manufacturers of hydrocyclones who claim that their systems can
achieve 5ppm oil conc if average oil droplet size is 25 microns
without the use of chemicals. Is this a reasonable claim?
Also, can centrifuges also provide
such separation between emulsified oil and water? Any advice will be
highly appreciated.
