Pennsylvania-American Water Company Piloting UV Disinfection
------------------------------------------------------------
PITTSBURGH, Feb. 26 /PRNewswire/ -- Pennsylvania-American Water
Company has begun a pilot program, in partnership with Calgon
Carbon Corporation and the Pennsylvania Department of
Environmental Protection (DEP), to study ultraviolet light
disinfection technology in the water treatment process at
the Company's Hays Mine Complex in Pittsburgh, PA.
The pilot involves the installation of an ultraviolet light
unit on one of the plant's filters to be used in addition to
traditional chlorination and filtration for water treatment
and disinfection. UV light technology is considered to be
superior in the water treatment process because of its ability
to inactivate various biological contaminants, such as Giardia
or Cryptosporidium cysts.
While chlorination has been -- and will continue to be -- an
effective step in water treatment, the use of UV technology can
provide an additional barrier against infection caused by
microorganisms. UV disinfection will not replace chlorination
but could act as a complement to traditional water treatment
practices. Forthcoming regulations on disinfection by-products
from chlorine usage make technologies such as UV disinfection
more applicable to water treatment, since UV is not known to
form any harmful by-products.
The UV disinfection pilot at Pennsylvania-American's Hays Mine
Complex will reaffirm the treatment effectiveness of the technology.
This will be completed in conjunction with a study currently
underway at the laboratory of PAWC's parent company, American
Water Works, Inc. (NYSE: AWK), in Belleville, IL.
The pilot at PAWC's Hays Mine Complex also charts the costs
associated with retrofitting a system with the technology, as
well as operational and maintenance costs. Data gathered from
this study will enable PAWC to design and construct efficient
UV disinfection systems within its water treatment facilities.
Calgon's UV unit, known as the Sentinel(TM), is one of the first
units to be manufactured in Pittsburgh since Calgon's recent
relocation to Neville Island, a suburban Pittsburgh township.
The unit -- running 24 hours a day -- will be under continual,
concurrent observation by computers at the Hays Mine Complex
and at Calgon's Neville Island facility.
The pilot program will be completed by July 2002.
Pennsylvania-American Water Company, a subsidiary of American
Water Works Company (NYSE: AWK), is the largest regulated water
company in the United States. The Company owns and operates 32
surface water filtration plants with a combined capacity of 332
million gallons of water per day. More than 7,700 miles of water
transmission and distribution lines deliver high-quality water
to more than two million Pennsylvanians. American Water Works
Company (NYSE: AWK) is the largest and most geographically diverse
investor-owned water utility business in the United States.
The Company's utility subsidiaries and affiliates now serve
approximately 10 million people in 23 states.

NOSWA Grants Two Contracts To New Consortium
------------------------------------------------------------
North of Scotland Water Authority (NoSWA) has recently granted
two contracts to the newly formed Leopold-Tulloch Consortium,
comprising PCI-Water (formerly PCI-Leopold) and Tulloch Civil
Engineering Limited. The contracts, won by the Consortium on
a competitive tender basis, were for novel spiral nanofiltration
plants at two locations, Kyle of Lochalsh and Onich, in the
Highland Region. The NoSWA agreements, although tendered for
separately, were ordered together to take advantage of a saving
scheme offered by the Consortium.
The forested area at Achnandarach, where the first membrane
plant for the Kyle of Lochalsh is being built, contains
archaeological sites that require protection. "We had to take
this unusual complication into account when planning site
activity," said Mike Hughes from PCI-Water. "To prevent damage,
site engineers have cordoned off a stone circle, in the middle
of the site while construction of the plant continues," he
said. The £1.5 million plant, which uses the novel spiral
membrane design, is the biggest such plant built by PCI-Water
to date. Treating 1,420m3 of colored surface water per day,
it supplies a population of around 3,500 in the Kyle of
Lochalsh/Shiel Bridge area.
The Consortium is also installing a second plant at Onich WTW,
at Gleann Seileach, near Fort William. This is phase three
of the construction programmed at Onich , which processes
420m3 of water per day, supplying a population of around 1,000.
The new £1 million plant will augment the nearby Ballachulich
water supply system, and again uses the PCI novel spiral
membrane design to remove color from the upland source waters
prior to consumption.
"Operational costs are cut dramatically using this spiral
design, when compared with conventional municipal spiral
designs, with no increase in capital costs," said Mike Hughes.
"This is the smallest spiral plant designed by us to date.
Whilst this size of plant has previously been designed using
tubular membranes, our use of spiral membranes in this case
shows that we are keen to offer the right system for each
customer."
Both turnkey contracts meet the full mechanical and electrical
requirements, of NoSWA, which means that no extra additional
client support is required in this area. At both sites, the
Consortium built new access roads and the Kyle of Lochalsh
site gained a new bridge. The Onich site required an intake
structure and both site contracts included a treatment plant
building. The buildings though are different. At the Onich
site, it is a steel framed, concrete panel clad structure
with a steel roof, whilst the building at the Kyle of Lochalsh
is of a steel frame, and all steel clad construction.
Reservoirs of 2,000m3 and 1,000 m3 were also built using
reinforced concrete, at the Kyle of Lochalsh and Onich sites
respectively.
These contracts, currently undergoing commissioning and test
were both completed within 49 weeks and are the first ones
awarded to the new Consortium. PCI-Water, has not collaborated
in this way with another company before, but it does so now
with the full approval of PCI-Water's parent company, Thames
Water. Working as the lead partner in the Consortium, PCI-Water
can widen the scope of its operations and is able to bid for,
and project manage, much larger contracts.

Causes of Seal Failures: Guest Article by Rich Hixon
------------------------------------------------------------
Just like a marathon runner, we would like our seals to
last till the end. But like many marathon runners, most
don’t finish or lack in quality of their performance.
Considering the large number of sealing materials available
today, no wonder that selection mistakes are made. Maintenance
engineers and purchasers should be aware of some general
guide lines that can make the selection easier.
First, dissimilar chemical structure is the key to fluid
compatibility. Seal compounds that are similar will tend to
dissolve each other, causing seal swelling and eventual
failure. Also fluid incompatibility is often blamed for the
degradation of a seal or o-ring when the real problem is
high temperature. This occurs in hydraulic systems where
the operating temperature of the fluid should be tin the 50C
or 120F range, but has increased substantially due to
increased pressure settings, modifications, restricted flow,
or a partially plugged heat exchanger.
The major reason for failure is improper installation.
Damage, misalignment, or no lubrication are just some of
the causes.
Some causes for seal failures:
-Misalignment of components
-Poor bearing lubrication
-Vibration of rotating components
-Contaminated fluids
-Twisting condition due to "soft foot" at mounting pads
-Poor component base plate mounting or grouting
-Rotor imbalance or shaft whip
-Inadequate flushing procedures during commissioning or
start-up after repairs
-Poor or careless seal or bearing installation
-Piping strains, due to misalignment or temperature variations
-Looseness of bolts and flanges
-Addition of incompatible fluids
-A dramatic change in temperature
-Unclean operating conditions (dirt ingestion)
-A change in filtration practices
When a seal fails, just don’t replace it. Determine the real
cause of failure.

Groundwater Replenishment Project Will Use 50% Less Energy
------------------------------------------------------------
FOUNTAIN VALLEY, Calif.--(BUSINESS WIRE)--Feb. 22, 2001--The
Groundwater Replenishment System, a water purification project
proposed by Orange County Water District (OCWD) and Orange
County Sanitation District (OCSD), could save 140 million
kilowatt hours (kWh) of electricity each year when compared
to importing water from Northern California.
If constructed, the energy savings for just Phase I of the
project -- which will produce 78,000 acre-feet of new water
-- is enough energy to supply 21,300 Orange County homes for
one year.
It takes twice as much energy to transport water to Orange
County from Northern California than it does to purify local
wastewater. Every gallon of water produced by the GWR System
is one less gallon of water that must be pumped here from
Northern California's Bay-Delta.
The GWR System is a water reclamation project that will
initially purify approximately 70 million gallons per day
of highly treated wastewater through membrane technology,
resulting in near-distilled quality water. Some of the
water will be injected underground to form a seawater
intrusion barrier along the coast.
The remaining water will be transported to Anaheim and
percolated into Orange County's large underground water basin
to help lower the mineral content of our groundwater. In
addition to providing a new, drought-proof supply of water,
the GWR System will also improve the overall quality of
Orange County's groundwater basin.
Highly treated wastewater looks like clear mountain stream
water, but contains viruses and bacteria and has a higher
than desirable mineral content. The GWR System's treatment
plant located at OCWD will remove all viruses, bacteria and
salts, creating near-distilled quality water.
Orange County Water District is a special agency that was
created by the California State Legislature in 1933 to
maintain and manage the groundwater basin under northern
and central Orange County. OCWD's groundwater basin supplies
75% of the water needs in Anaheim, Buena Park, Costa Mesa,
Cypress, Fountain Valley, Fullerton, Garden Grove,
Huntington Beach, Irvine, La Palma, Los Alamitos, Newport
Beach, Orange, Placentia, Santa Ana, Seal Beach, Stanton,
Tustin, Villa Park, Westminster, and Yorba Linda.
Orange County Sanitation District is the largest wastewater
treatment system west of the Mississippi River, serving
2.2 million residents in northern and central Orange
County.

Mr. Case is looking for help with chlorides removal: help needed
I am planning to install a wwt-pretreatment system in a ship
yard for treatment of bilge water (salt water). We have no
problem with oil, dissolved heavy metals and solids removal but
need to reduce chlorides from 2,400 ppm to <50 ppm.
We have tried nano-filtration and similar but can only get to
1,200 ppm. I have heard that ammonia may help.
Any suggestions, ideas?

------------------------------------------------------------
This week's photo is of a 24-inch-in-diameter Slurrycup grit
classifier with a one-cubic-yard Grit Snail dewatering unit,
located at the Florence, Oregon WWTP. Eutek® Systems, Inc.
meets the challenges of separating and classifying grit as
small as 50 micron (270 mesh), while providing secondary
washing to minimize organic content. The 'all hydraulic'
Slurrycup has no internal moving parts, increasing operating
reliability. Applications include grit washing, snail shell
removal, and primary sludge degritting.
