| Grit Removal
: EVT To Publish Test Results From WWTP
 FORT
LAUDERDALE, FL -- Enviro Voraxial Technology, Inc. announced
today positive preliminary data from the Company's Voraxial
4000 Grit Separator, which is operating at the Northwest
Regional Water Reclamation Facility (NWRWRF) located in
Tampa, Florida. The Company has been operating the Voraxial
4000 Grit Separator at the wastewater facility for
approximately four months.
In the data, which has been
verified to date, the Voraxial 4000 Grit Separator at the
NWRWRF is achieving an overall separation efficiency between
85% and 89%. This means that 85% to 89% (by weight) of the
particles in the influent wastewater was removed by the
Voraxial 4000 Grit Separator.
"These results are far superior
to the overall removal efficiency that is typical for
current grit separation technology," said Dr. Dan Samela,
Manager of Engineering and responsible for the testing
protocol. "Additionally, the eighty-nine (89%) percent
efficiency exhibited by the Voraxial 4000 Grit Separator for
removal of particles down to thirty-six (36) micron size is
unmatched by any other system on the market today."
To validate the efficacy of
EVTN's revolutionary technology, the Voraxial Grit Separator
was incorporated at the head-works of a five million gallon
per day (5MGD) wastewater treatment plant. Test requirements
included processing raw wastewater including on-site plant
drain flow, a sludge side stream flow from an adjacent
sludge treatment plant, and spent filter backwash waters.
Test analyses were performed,
verified, and reported by an independent laboratory that is
under contract with the Hillsborough County Water Department
to act as an "arms-length" observer for this study.
Dan Samela, PhD, has prepared an
interim report containing verified data that the Company has
begun to circulate among interested professionals within the
industry. The Company intends to present the results of its
study at WEFTEC.04 (Water Environment Federation's Technical
Exhibition and Conference, 2004), which will be held in New
Orleans in October 2004.

NCPPP to Hold Workshop :
Planning For Texas
 Washington,
DC -- Total capital costs of water supply, water
infrastructure, wastewater treatment, and flood control in
Texas through 2050 are now estimated to be $109 billion.
Decision makers at all levels of government will face the
daunting task of determining the most cost-effective and
timely options to deliver safe drinking water to the tap, to
protect lives and property from flood waters, and to assure
wastewater treatment expands to accommodate Texas' growing
population.
The
infrastructure challenges of tomorrow demand that new and
innovative project delivery approaches be considered and
made available, so decision makers have more options from
which to choose.
Public-private partnerships (PPPs) may provide such options
and flexibilities. PPPs are a common delivery method in many
states. Advocates of PPP list among the benefits of these
partnerships:
· A
substantially accelerated delivery of new infrastructure
where growth has outpaced treatment plants and pipes;
· Lower capital, operation and maintenance costs that result
in affordable user fees for ratepayers;
· Reasonable performance and cost guarantees;
· Enhanced risk management that translates into lower
life-cycle costs for rate-conscious utilities; and
· Possible innovative financing options that minimize
investment burdens to cash-strapped communities.
Equally important, PPPs maintain the necessary public sector
control and oversight to ensure integrity of the process and
the reliable, safe delivery of public services.
Although proven successful throughout the U.S., there can be
hurdles to the implementation of PPPs where the "if it ain't
broke, don't fix it" approach has worked well and where
alternative delivery might be considered "new-fangled.” In
some states, these hurdles can be legal, regulatory or a
matter of public policy, but statutory obstacles can be
addressed to create an environment conducive to implementing
successful PPPs.
To
explore the use of PPPs in helping to meet the water needs
for Texas, a one-day workshop “Partnerships for Water
Infrastructure” will be held in Austin on Thursday, August
19 at the Renaissance Austin Hotel. The meeting is being
sponsored by The National Council for Public-Private
Partnerships (NCPPP), in conjunction with the Texas Water
Development Board and the Texas Municipal League.
The
workshop will cover the fundamentals of PPPs, and the
specifics of how they can be successfully implemented in
Texas. The program will feature Texas case studies which
demonstrate the viability and benefits of PPPs. Details of
proper risk allocation for PPPs and financing tools will be
included. The Texas legal environment for PPPs will be
examined and the benefits to Texans discussed. Experts from
both the public and the private sectors will be on hand to
share their expertise and experiences.
The
complete listing of speakers and topics, as well as
registration and hotel information is available on the Texas Water Development Board Web site,

OilTrap : New Generation of
Wastewater Treatment
 Portland,
OR -- OilTrap Environmental, a leading manufacturer of
electrocoagulation (EC) wastewater treatment systems, has
introduced a new generation of electrocoagulation wastewater
treatment systems designed for treating extra-complex waste
streams.
ElectroPulse will process up to 100 gallons per minute (GPM)
of wastewater and is typically of a quality that can be
recycled or discharged to a sanitary sewer. Average
treatment cost is only $0.003 per gallon or $3.00 per 1,000
gallons.
ElectroPulse system uses electrocoagulation, an
electricity-based technology for treating complex waste
streams economically and on-site. The EC treatment process
has proven successful in removing a variety of contaminants
that are impossible or too expensive to be removed by
filtration or chemical treatment systems. Among these
contaminants are emulsified oil, TPH (Total Petroleum
Hydrocarbon), suspended solids and heavy metals. Generally
heavy metals are reduced to a hydroxide, allowing sludge
that is separated through the ElectroPulse treatment
process, to pass a TCLP (Toxic Characteristic Leaching
Procedure) test.
Packaged with on-board automation, the ElectroPulse system
is fully automated, which dramatically reduces the cost and
time of maintenance often associated with on-site wastewater
treatment systems. Also, there are no filters to clean or
replace.
OilTrap Environmental, which has been manufacturing
electrocoagulation water treatment systems since 1993,
provides not only highly effective technology but a total
solution approach through system design to meet your
specific needs and requirements. OilTrap Environmental
offers a FREE waste stream feasibility study using a
representative sample of wastewater from your facility.

Weekly Update #39
: Iraq Reconstruction
 Washington,
DC -- Weekly Update #39 -- This fact sheet
highlights overall accomplishments and some
weekly activities from USAID’s reconstruction
efforts in Iraq.
For more
information on USAID’s programs in Iraq please
see:
www.usaid.gov/iraq
Program Overview
USAID assists
Iraqis in reconstructing their country by
working within the Coalition Provisional
Authority (CPA). USAID programs are
implemented in coordination with the United
Nations, World Bank, International Monetary
Fund (IMF), Coalition country partners,
nongovernmental organizations (NGOs), and
private sector partners. The USAID Mission in
Iraq carries out programs in education, health
care, food security, infrastructure
reconstruction, airport and seaport
management, economic growth, community
development, local governance, and transition
initiatives.
Water and
Sanitation, Accomplishments to Date:
• Rehabilitating
sewage and water treatment plants that
currently by-pass untreated sewage generated
by millions of people into the Tigris and
Euphrates Rivers.
o Repairing and
rehabilitating water systems throughout Iraq.
o Repaired hundreds of breaks in Iraq’s
critical and long neglected water network,
significantly increasing water flow.
Highlights this
Week:
• A new
collaborative effort between USAID and the
U.S. Military is implementing community
development and infrastructure projects in
some of Baghdad’s poorest and most volatile
areas in an effort to improve the quality of
life for the city’s residents.
Because evidence
directly links security to the provision of
essential services (particularly electricity,
water and sanitation), USAID and the
military’s joint efforts targeted immediate
assistance to unstable neighborhoods. The
positive results underline the success of a
new approach for civil-military collaboration
in post conflict countries.
These new projects
include both quick-impact labor intensive
community improvement projects as well as
long-term infrastructure development projects.

Mr. Hameed wants information on distilled water:
I am working on a project of MSF
distillate potabilization plant. Water to be used for
drinking purpose. One option is to inject CO2 in the
distillate water and then passing this water through
limestone filters to achieve the desired pH, alkalinity
and hardness. The other option is to inject CO2 and
then injecting milk of hydrated lime to the distillate
water.
Can anyone provide me the comparison of
these two systems, i.e., what are advantages and
disadvantages of each system & which one is the better
system for distillate potabilization.

Saint John Installs
TecStore Tank
Bringing its water system into
the 21st century and complying with provincial standards
were the main goals of the city of Saint John, New
Brunswick, when it decided to install a new potable water
tank. The city’s old riveted tank built in 1935 had
a capacity of 250,000 imperial gallons — not enough to
meet the needs of the 25,000 customers in the city’s
western section, especially in case of an emergency.
