California :
Parsons Will Manage All American Canal Lining Project
 PASADENA,
CA -- Parsons received a four-year contract award from the
Imperial Irrigation District (IID) to manage the design and
construction of a new 23-mile canal parallel to the existing
All American Canal. The IID is the largest irrigation
district in the United States with nearly 500,000 acres of
irrigated lands.
The All American Canal in
Imperial County, California, is the largest irrigation
supply canal in the U.S., providing agricultural and
municipal water supplies to nine cities and nearly 500,000
acres of agricultural land throughout the Imperial Valley.
The existing canal delivers approximately 3.1 million
acre-feet of water annually to IID. However, it is currently
unlined, which results in substantial seepage of valuable
water resources.
Parsons, over a four-year project
design and construction cycle, is providing program and
construction management services for developing this new
23-mile-long canal. The capacity of the All American Canal
is about 10,000 cubic feet per second. Approximately 25
million cubic yards of sand will have to be excavated as the
canal runs through approximately 14 miles of sand dunes, and
then the new canal prism will be lined with concrete to
control seepage.
Upon completion, the new
concrete-lined canal will conserve approximately 68,000
acre-feet of water annually. One acre-foot of water is
325,900 gallons, or enough to sustain two families for a
year.
"Parsons is honored to be
involved in such a historic California water project and a
project which will conserve additional Colorado River
water," states David Backus, Parsons Group President.
Considered an engineering marvel,
the current All American Canal begins at the Imperial Dam on
the Colorado River about 20 miles northeast of Yuma,
Arizona. Dropping a total of 175 feet between the Imperial
Dam and the Westside Main Canal, the All American Canal
extends south, then west, following the Mexican/American
border most of the way.
Parsons has worked on many
landmark water projects including the Olivenhain Dam in San
Diego County; the Southern Nevada Water Authority's Lake
Mead water purification and distribution project providing
water to Las Vegas Valley, and the $2 billion Diamond Valley
Lake project which doubled the water surface storage
capacity for Southern California.
Parsons is a leader in diverse
markets, including water and wastewater systems,
infrastructure, transportation, facilities, industrial
processes, communications, advanced technology,
environmental, and planning. The company provides technical
and management solutions to federal government customers
worldwide as well as to state and local governments and
industrial customers. For more information on Parsons visit

Ionics : Launches Its Next
Generation of TOC Analyzers
 BOULDER,
CO -- Ionics Instrument Business Group (Ionics Instruments),
a Boulder-based manufacturer of scientific instrumentation
and a subsidiary of Ionics, Incorporated, today announced
its new Sievers(R) 900 Series Total Organic Carbon (TOC)
Analyzers. The new, three-model 900 Series includes the 900
Laboratory, 900 On-Line, and 900 Portable TOC Analyzers,
offering improved analytical performance, ease of use,
productivity, and reliability. Also introduced was the
optional 900 Autosampler.
The
Sievers 900 Series TOC Analyzers -- designed with customer
feedback -- represents the next generation of the Sievers
800 TOC Analyzer used by more than 3,000 customers
worldwide. Key enhancements to the 900 Series include
improved precision and accuracy across an extended 30 ppt to
50 ppm dynamic range; 4-minute analysis time; automated
calibration, verification, and reagent adjustment routines;
a smaller instrument casing; a touch screen display for
quick access to real-time or trend data, and a USB port for
data transfer.
For
laboratory use, the 900 Autosampler offers up to 156% more
sampling capacity than its Model 800 predecessor. In
addition, the 900 Autosampler offers user-defined random
sampling capability for added flexibility and convenience.
The Sievers DataPro 900(TM) software, which integrates the
Autosampler with a 900 Analyzer, offers new productivity
features and versatile TOC data control.
"The
primary driver behind the Model 800 redesign was customer
input," said Stephen J. Poirier, vice president of sales and
marketing for Ionics Instruments. "The 900 Series
incorporates many features from our customers' 'wish list,'
yet maintains the core strengths of the Model 800. The new
900 Series builds upon our patented membrane conductometric
TOC detection technology, improves the easy set-up and
operation for which Sievers TOC analyzers are known, and
offers better accuracy and analytical range for TOC
measurement. In addition, we've incorporated advanced
materials and a more modular design for maximum reliability
and minimal maintenance."
The
900 Series Analyzers are used for general TOC monitoring in
pharmaceutical, municipal, semiconductor, and power
applications. Each 900 Series model has new features
specifically designed for its intended application and
operating location.
Like
the Model 800 predecessor, the 900 Series TOC Analyzers are
easy to set up, operate, and maintain. With minimal
training, an operator can analyze samples in less than an
hour. Unlike many competitive analyzers that use
technologies such as non-dispersive infra-red, the 900
Series Analyzers require no external gasses or reagents,
offer 12-month calibration stability, and require
approximately two hours of maintenance annually.
For
more information on the Sievers 900 Series TOC Analyzers

800-255-6964.

Wastewater : Super Shredder Cuts
In-Line Solids
 Livingston,
NJ -- The Super Shredder® in-line disintegrator easily
reduces tough solids directly in sludge or raw sewage lines.
The unit combines unsurpassed grinding capabilities with
streamlined, easy to maintain features. Its innovative
design provides a high level of open area to fluid flow
making the Super Shredder ideal for applications requiring a
heavy duty size reduction processor that can handle high
flows with minimal headloss.
The
Super Shredder features a patented “spherical shredding”
mechanism that cuts and shears tough sewage solids into fine
bits. The hard faced stainless steel cutters offer
unsurpassed wear resistance. Because of the spherical rotor
design, the Super Shredder has far fewer moving parts and
requires much less maintenance than units with banks of
cutter disks. With two easily replaceable one piece cutters,
maintenance is convenient and down time is minimal.
Included with the Super Shredder is a S-250 Auto-Reversing
control system that senses jam conditions and automatically
reverses.

Slurry Pumps : HI
Enlists Participants To Review Draft Standard
 PARSIPPANY,
NJ -- The Hydraulic Institute (HI) is seeking
qualified individuals to participate in the
review process of a newly completed standard
for the definition, selection, application,
operation and maintenance of centrifugal
slurry pumps. Believed to be the first of its
kind, the scope of this new standard includes
slurry pump types, types of slurries, slurry
limitations, slurry solids effect on pumps,
pumping of froth, pump wear, and application.
The standard
provides requirements for wet-end and bearing
housing shaft seals, establishes allowable
nozzle loads, and provides a data sheet that
can be used by purchasers and vendors to
exchange information.
Individuals and
organizations directly and materially affected
by this standard are asked to contact HI.
These parties include pump users and
specifiers, producers, standards developers,
government agencies, and general interest
groups. HI is currently assembling a canvass
list of all interested parties who wish to
review the drafts and will submit the list to
ANSI in order to meet its open canvass
requirements.
"Establishing
standards for slurry pumps is more complex
than for other rotodynamic pumps. There are
more variables to consider, such as the size,
hardness, abrasiveness, and density of the
particles being transported," explained Gregg
Romanyshyn, technical director for HI.
"In turn, there are
many applications for slurry pumps that users'
specifications will vary significantly. For
example, the requirements for slurry pumps
used in the paper and pulp industry are
different than those used in the chemical or
mining industries. We encourage participation
in the ANSI canvass process to ensure that the
new standards we establish will address
different user requirements," he added.
To participate in
the ANSI/HI canvass, contact Karen Anderson,
Administrator, Technical Affairs,
kanderson@pumps.org or call(973) 267-9700 x23.
The 87-year old
Hydraulic Institute, the largest association
of pump producers in North America, serves
member companies and pump users by providing
product standards and forums for the exchange
of industry information.
To learn about
membership in the Hydraulic Institute,
prospective members are invited to call HI
Executive Director Bob Asdal at (973)
267-9700. Information on the Hydraulic
Institute, its services, standards,
publications and meetings, can be found at the
HI web site at
www.pumps.org and
www.pumplearning.org. Requests may
also be faxed to (973) 267-9055 or mailed to
Hydraulic Institute 9 Sylvan Way, Parsippany,
NJ 07054.

Mr. Howley wants info on pressure tank usage:
Is there any practical or effective CT
storage in a pressure tank?
A school is on a well system, with standby
chlorination. Regular bleach, e.g., Clorox, is added to the
well outlet before two hydropneumatic tanks (Well-X-Trol
WS-350 rated at 119 gallons volume) in parallel. There are
four storage tanks in series downstream of the pressure
tanks, each about 130 gallons.
The school's water system operator says
that the original designer included the pressure tanks in
the contact time calculation. I think that is wrong, and
only the four storage tanks provide practical contact time.
Opinions are requested.

Mr. Oakes wants
help with oily wastewater:
I am currently doing a project for my
HNC engineering qualification. The project is about
wastewater in my place of work. I need to research the
waste, types of treatment and then gain quotes and work
out a payback period. At the moment I'm having great
difficulty getting quotes for machines because no company
seems to want to help a student!
If there is anyone out there who would be
able to help me it would be greatly appreciated. The quotes
would only have to be fairly rough. The machines I'm
currently looking at are dissolved air flotation. But I'm
open to suggestions/quotes on other suitable machinery. The
waste water in question is containing oil, and metal solids.
and another waste contains sodium hydroxide.
