UV Disinfection System Receives
Certification
 FORT
WASHINGTON, PA -- Severn Trent Services’ UltraDynamics®
8102-HO-200 ultraviolet (UV) disinfection system has
received validation test certification that conforms to the
protocols prescribed by the U.S. EPA’s Ultraviolet
Disinfection Guidance Manual (UVDGM). The UVDGM provides
technical guidance on the application of ultraviolet light
for the disinfection of drinking water by public water
systems.
The 8102-HO-200 UV system
provides an ultraviolet dose of 30,000 to 40,000 micro-watt
seconds per square centimeter at a wavelength of 254nm
ultraviolet energy for the deactivation of microorganisms.
After validation testing, the .8 million gallon per day
8102-HO-200 UV system was installed at the Leslie Water
Treatment Plant, Northeast, Maryland. It is expected to be
fully operational later this year.
UV light is proven to be an
effective method for inactivating waterborne pathogens and
viruses, including Giardia Lambia cysts and Cryptosporidium
Parvum oocysts. Moreover, UV does not pose the handling
safety concerns of traditional disinfectants such as
chlorine.
The test plan for the validation
was written by HydroQual, Inc. which also conducted all
testing and prepared the final validation report.

WHO Seeks Comments on
Desalination Guidance
 Denver,
CO -- Noting that desalination of seawater and brackish
water "adds several dimensions of complexity beyond what is
typically involved in the production of drinking water," the
World Health Organization has released draft guidance on the
health and environmental aspects of desalination.
WHO seeks comment by October 31
on the draft of "Desalination for Safe Water Supply" and
expects to publish a final version in English by year's end.
An Arabic translation will also be prepared using funding
provided by the Kuwait Foundation for the Advancement of
Science.
WHO noted that desalination
technologies are improving and growing rapidly worldwide and
have "significantly broadened the opportunities to access
major quantities of safe water in many parts of the world."
Since desalination was introduced about 50 years ago, more
than 12,000 desalination plants have gone into operation,
producing about 40 million cubic meters of water per day ?
despite the high cost of the technology, according to the
report.
"Costs are still significant but
there has been a reducing cost trend, and the option is much
more widely available," the report says.
While WHO Guidelines for
Drinking-Water Quality cover a broad spectrum of
contaminants, the 2000 Berlin Coordinating Committee meeting
requested additional guidance in the area of desalination
because it uses nontypical source waters technologies, which
might not be adequately addressed by existing WHO
guidelines.
Of particular concern are the
presence of microbes from coastal and marine sources and
chemicals in source water or that are not well removed by
the desalination process.
The monograph is divided into
five segments: technology, health, marine and sanitary
microbiology, monitoring and environmental impact
assessment. Each section was produced by an international
committee of experts and concludes with recommended
guidance. Some also identify research issues.

HYDAC Solves Municipal Well
Water Problem
 Bethlehem,
PA -- As wells go deeper in the ground to find sources of
potable water, more contamination is removed and placed into
production. Indian River County Municipal Water Services
located in Vero Beach, Florida knows this to well. Indian
River is a source of potable water production for the local
county. As they remove water from deeper wells, silt and
sand began plugging their micro pre-filters on a high
frequency basis.
Gerald
LeBeau, Superintendent of Water Production at Indian River
needed a solution to the plugging of the pre-filters,
resulting in increased costs and short filter life. The
opportunity for HYDAC was to find a way to remove the silt
and sand before the pre-filters, thus gaining longevity of
these pre-filters and adding life saving dollars.
HYDAC
looked at the opportunity and came up with a solution to
install their Automatic Backflush Filter directly filtering
the source of the well water. The well water is passed
through the HYDAC Automatic Self-Cleaning RF3-4 Backflush
Filter and the water is cleaned of any solids, sand or silt
that may come from the well.
Gerald
LeBeau, stated that the HYDAC Filtering System provides
Indian River with more lifetime on the pre-filters, thus
saving money on an annual basis. The HYDAC Backflush
Filtering System has doubled the change out time of the
pre-filters from every 45 days to approximately 90 days.
Also, being a self-cleaning system for Indian River’s
potable water, manpower can be redirected to more critical
plant areas at Indian River.

Energy
from Biomass and Waste Expo
 PITTSBURGH,
PA -- While many still regard waste as a liability, an
increasing number of proponents of clean, domestically available
fuels see it as an asset. Energy recovery from waste can help
reduce the dependence on oil imports and protect the
environment.
At America's first international
exhibition and conference on "Energy from Biomass and Waste",
(EBW), manufacturers of environmental technology and
stakeholders from waste management, municipalities,
energy-intensive industries, and the farm economy meet to
discuss the value of waste. The EBW Expo & Conference will be
held on September 25-27, 2007 at the David L. Lawrence
Convention Center, Exhibit Hall B, in Pittsburgh, Pennsylvania.
Waste-to-energy facilities and
landfill-gas-recovery sites are what first comes to mind, but
there are more options for waste as a resource: biofuels from
plastics waste; so-called refuse-derived fuels made from
residential waste and used to substitute coal in power plants;
bioenergy from wastewater; and biogas from cow manure and
chicken litter for heat and power generation. The "Waste to
Value" session of the EBW Conference focuses on available
technologies, best-practice reports, financing, market trends,
and legislative issues.
EBW's mission is to make attendance
of the expo and conference affordable for a wide range of
stakeholders. Thanks to the support of sponsors like Allied
Waste and the Pennsylvania Department of Environmental
Protection, entrance fees can be kept at only $50, with tickets
giving unlimited admission to the technology exhibition and all
conference sessions.
Further sponsors of the EBW Expo &
Conference include: Herbert, Rowland & Grubic, Inc.; The
Pennsylvania State University; Robert-James Sales, Inc.; TowPath
Renewables; and The West Penn Power Sustainable Energy Fund.

Mr. Hoffmaster wants to know about membrane systems:
I am in the process of
looking into a membrane expansion for one of our clients
here in Texas. I only have experience with conventional
systems and was looking for some information on best
technology in regards to O&M cost and longevity of
membranes.
This is a surface water plant
with mild turbidity so most likely would require
pre-filtering. Any info is welcome.

Discovery Channel Series seeks
experts:
I got an email today from a
TV production company in London seeking experts in the area
of filtration and desalination. If you think you can help or
make a recommendation, please feel free to contact Mr.
Chapman. Here is the email as I received it:
++++++++++++++++
Dear Joseph
Impossible Pictures are
producing a new environmental engineering series for the
Discovery Channel concentrating on technologies with the
potential to alleviate climate change.
One story I'm investigating
involves microfiltration of seawater, removing particles
down to 0.3 micron diameter. The system we're looking at has
a minimum flow rate of 160 gallons per minute.
I would be really grateful if
you could recommend anyone in industry or academia who we
should be speaking to about this as part of the series.
Thank you for your time and
if you have any questions or need more information please
feel free to drop me a line.
Kind regards,
Nick Chapman
