Ozone Disinfection : Municipal
Water Distribution Pipelines
 Benicia,
CA -- Water quality leaving treatment plants of North
American water utilities is exceptional. Unfortunately, on
the way to customers this safe and high quality potable
water may become contaminated in miles of distribution
system.
After two years of research by
Denver Water and Camp Dresser and McKee (CDM) a new process
to disinfect pipelines using ozone as the disinfectant is
being employed in real world daily operation. The
patent-pending Rapid Pipeline Disinfection system uses mass
transfer and degas technology from Mazzei Injector-GDT Corp.
and Floating Plate™ air-cooled ozone generating technology
from Pacific Ozone Technology.
The new trailer mounted Rapid
Pipeline Disinfection ozone system receives water from a
local fire hydrant using a fire hose. Ozone is produced from
pressurized oxygen cylinders by an air-cooled 180 g/h
Pacific Ozone Technology ozone generator and is added to the
hydrant water using a packaged pressurized GDT™ ozone mass
transfer system. More than 90% of the ozone gas is dissolved
in the GDT process with off-gas discharged through an ozone
destruct unit also from Pacific Ozone Technology.
The new ozone system can
disinfect a pipeline in one hour, compared to traditional
methods using chlorine that can take up to 24 hours.
The summary of benefits recognized using ozone disinfection
includes:
1. No dechlorination step -
chemical and labor cost reduction.
2. No hazardous chemical storage or transportation -
permitting ozone to be generated on site.
3. Effective and rapid disinfection - minutes not hours/day
before flush and sampling.
The Rapid Pipeline Disinfection
ozone trailer is typically operated for 30 minutes. The
residual ozone in the pipeline is allowed to naturally
convert to oxygen (less than 1 hour) as compared to
chlorination - dechlorination that can take up to 24 hours.
Denver Water has been tracking
operational results of both the ozone and
chlorination-dechlorination disinfection systems on 6 to 12
inch mains with runs up to 6,000 feet for almost two years.
They have found first pass success rates to be virtually
identical at 87%.

Pipe Disinfection ozone system, contact:

Drinking Water Week : Water
Professionals Focus on Security
 DENVER,
CO -- As National Drinking Water Week continued today, water
professionals acknowledged the important strides made since
9-11 to secure North American water supplies and urged
citizens to be aware of unusual activity near water
facilities or sources.
Water
professionals, security experts and emergency responders
gathered last month in Oklahoma City to assess the state of
water security at the third Water Security Congress, hosted
by the American Water Works Association (AWWA). Officials
examined the latest in contamination warning technologies
that are improving chemists’ ability to detect undesirable
substances in drinking water. More than 50 manufacturers of
security technologies were present to share the latest
innovations with attendees.
"Significant progress has been made in contamination
monitoring, physical and cyber security, information sharing
and emergency response planning," said Jack Hoffbuhr, AWWA
executive director. "But each citizen has a role to play by
being the first line of defense against those who would harm
our water supplies. If we see unusual activity near a water
supply, hydrant or facility, we should report it immediately
to the police."
AWWA
estimates water utilities throughout the United States have
spent approximately $2 billion since 2002 to upgrade
security with better fencing, cameras, locks and other
physical improvements. J. Alan Roberson, AWWA director of
security and regulatory affairs, said security has become
part of the fabric of everyday decisions at water utilities.
"Being
in Oklahoma City for the Water Security Congress 10 years
after the terrorist attack there was a poignant reminder for
water professionals that we have to remain vigilant,"
Roberson said. "If we once applied water security like a
protective shield, it now as to be in our bones."
AWWA
is the authoritative resource for knowledge, information,
and advocacy to improve the quality and supply of drinking
water in North America and beyond. AWWA is the largest
organization of water professionals in the world. AWWA
advances public health, safety and welfare by uniting the
efforts of the full spectrum of the drinking water
community. Through our collective strength we become better
stewards of water for the greatest good of the people and
the environment.

BV : To Study Impacts Of
Membrane Residuals
 Kansas
City, MO -- Black & Veatch, a leading global engineering,
consulting and construction company, announced today that it
has been awarded a contract to study the impacts of membrane
treatment residuals, such as concentrate and membrane
cleaning wastes, on wastewater and advanced wastewater
treatment plant operations and processes.
The
research project is sponsored by the Joint Water Reuse and
Desalination Task Force (JWR&DTF). In addition to the
WaterReuse Foundation, which is managing the project for the
JWR&DTF, funding partners include the U.S. Bureau of
Reclamation, California State Water Resources Control Board,
Awwa Research Foundation (AwwaRF), and Water Environment
Research Foundation (WERF).
Membrane processes continue to gain in popularity for
potable water treatment and water reclamation applications.
Microfiltration, ultrafiltration and nanofiltration
effectively remove disinfectant byproduct precursors,
pathogens such as Cryptosporidium, and other undesirable
constituents while reverse osmosis and electrodialysis are
increasingly employed to desalinate seawater and brackish
water. Also growing, however, is the quantity and percentage
of residual wastes from membrane filtration and cleaning
that are disposed to community wastewater systems. Concern
about how these concentrated contaminants affect wastewater
and advanced wastewater treatment plant operations and
processes is understandably rising as well.
“We
realized that multiple organizations within the water
industry needed to work together to identify and mitigate
the impacts of membrane process residuals on treatment
processes and effluent quality,” said WateReuse Foundation
Director of Research Programs Jeff Mosher. “Black & Veatch
assembled a team with the membrane, reuse and residuals
expertise necessary to provide both in-depth understanding
and big-picture solutions for this complex issue.”
Membrane systems generate backwash discharges that contain
raw water solids, pathogens, algae and possibly chemical
residues; solids and sludge created by concentrating the
solids removed from the raw water flow; and spent cleaning
solutions with high levels of chlorine and other cleaning
chemicals in addition to most of the raw water contaminants.
“An
increase in total dissolved solids concentration entering
wastewater systems can adversely affect settling, inhibit
biological treatment and increase aquatic toxicity—which in
turn can limit a utility’s disposal and reuse options,” said
Black & Veatch Principal Investigator Alan Rimer, Ph.D. “We
are excited about this opportunity to develop
recommendations that will enable utilities to improve
effluent quality and keep their options open.”
The
employee-owned company has more than 90 offices worldwide.
Black & Veatch is ranked on the Forbes “500 Largest Private
Companies in the United States” listing for 2003. The
company’s Web site address is

Mr. Ming wants to know more
about sand filters:
Does the continuous sand
filter become a dependable and excellent filter? I read the
article 'Central-Flo Upflow Continuous Backwash Filters
Perform' a few weeks ago and was interested in this filter.
I first heard about the
continuous sand filter about 3 years ago and thought the
backwash system and upflow design is great. There are a few
company that has built the filter recent years.
I want to know more about the
application. Any information will help.
