Degradation of Polluted Ground
Water Modeled
 Utrecht,
The Netherlands -- Dutch researcher Phil Ham has developed
mathematical models to calculate the natural degradation
capacity of polluted groundwater. As a result of this, it
can now be predicted whether a polluted area will become
larger or smaller. In the latter case, expensive remediation
methods can be avoided.
Groundwater under contaminated
sites, such as waste disposal sites and industrial areas, is
often polluted. Such a polluted groundwater plume can grow,
shrink or remain stable due to an interplay between
physical, chemical and biological processes.
Phil Ham has devised mathematical
expressions to determine the size of a plume and to assess
the natural degradation capacity of contaminated sites. His
analytical models calculate the reactive transport of
dissolved matter in water through porous soil and the
characteristics of the mixing processes. Such a
scientifically-supported method had not previously been
available.
Within the world of engineering
there is a high demand for mathematical models that allow
accurate predictions to be made. If it can be calculated
whether a plume will decrease in size or remain stable,
invasive and expensive remediation methods can possibly be
avoided.
The results of this study enable
predictions to be made about the effectiveness of natural
degradation as a responsible alternative to aquifer
remediation.

Hillsborough County Awards Sewer
Assessment Contract
 Wakefield,
MA -- Hillsborough County, FL has awarded InfraMetrix, LLC
an $8.7M contract to verify and update the County’s current
sanitary sewer system information and to compile a
comprehensive understanding of the physical characteristics
and condition of all of the sanitary sewer assets.
InfraMetrix’s assessment will cost-effectively and
comprehensively assess the structural condition of the
County’s manholes and gravity sewers to help the County
identify those with the greatest risk of hydraulic
deficiencies or structural failure to proactively avoid
future sewer back-ups or overflows.
Hillsborough County currently provides sanitary sewer
service to approximately 135,000 accounts in the
unincorporated area of Hillsborough County. All of the
information collected in the field using the CUES/IMX truck
mounted zoom camera, including the results of the condition
assessment of manholes and pipelines, will be entered into a
personal database for integration into the County’s GIS and
CAMS databases.
According to InfraMetrix president William DiTullio, the
firm’s unique technologies and software tools help utilities
minimize sewer overflows by economically collecting
real-time data about sewer system performance under actual
operating conditions. “We are confident that our stationary
truck mounted boom camera systems will provide the level of
detail and picture quality needed to perform a thorough
assessment of the condition of the County’s manholes and
pipelines. Additionally, our CUES/IMX camera sees farther
than hand-held pole cameras, an essential requirement for
improving system management and performance.”
Nationwide, sanitary sewer overflows (SSOs) release billions
of gallons of untreated wastewater into rivers, streams and
coastal waters, causing water quality impairments, beach
closures, drinking water supply contamination, and other
environmental and human health problems. Sewer overflows are
enforcement priorities for USEPA, which since 1998 has
concluded over 40 CSO and SSO enforcement cases representing
more than $14 million in civil penalties. It is projected
that over $50 billion will be spent on reducing CSO volume
over the next 20 years.

Altela Licenses New Desalination Technology
 TEMPE,
AZ -- Arizona Technology Enterprises, LLC (AzTE)
announced today that Altela, Inc., a leading
desalination product and service company, has acquired
the worldwide exclusive rights to unique low- cost water
purification technology developed at Arizona State
University (ASU).
Under the terms of the
transaction, Altela acquired the exclusive worldwide
license for the core intellectual property relating to
the "dewvaporation" water desalination technology
through AzTE, ASU's technology commercialization
company. Altela will continue to develop and
commercialize this newly patented desalination
technology and incorporate it into its AltelaRain(TM)
water desalination systems. The exclusive license is
based on technology initially developed by Dr. James
Beckman, a professor at ASU.
This unique water
purification technology removes 100 percent of the
dissolved salts and other contaminants from industrial
waste waters and undrinkable brackish waters found
throughout the world - representing the first new
low-cost water desalination technology in the last 50
years.
"We are delighted to continue
and expand upon our already-existing good relationship
with ASU, AzTE, and Prof. Beckman," said Altela's CEO
Ned Godshall, "and this exclusive license will now
accelerate our plans to commercialize this exciting and
elegant technology for all water desal applications."
According to Peter Slate, CEO
of AzTE, "This important technology has far-reaching
applications in both developed and developing markets
throughout the world. We feel that the Altela team has
the breadth of knowledge and creativity to take
advantage of all of these opportunities." Michael Crow,
President of Arizona State University, added that "this
ASU dewvaporation platform is one that we view as
disruptive to current water purification processes. It
will also provide a low-cost option to purify water in
regions where identifying sources of fresh water is
challenging."

Ms. Anderson needs help her Biotower and COD:
The Biotower based effluent
treatment plant that we use to reduce COD by around 80% has
served us well over the years. At least 80% of the COD which
is fed to the tower is in the form of ethanol.
Recently, performance has
been affected by an unavoidable elevation in ethanol
concentration. Efficiency has dropped to 60%, but this
is presumably a consequence of the higher than specified COD
loading.
We now have a drop in pH
across the tower - the product has been at a steady pH 3.9
for a number of days. Is this simply a reflection of
higher acid production from the increased ethanol oxidation
products? In any event, what can we do to de-stress
the situation?
A pH adjustment system is in
place, so can assume supply at pH 6.4 until verification
checks are completed.

Photographs
This week's
photo is of DAF flotation of waste. The IWWS method of
mixing chemistry, bubbles and wastewater produces large
buoyant particles (floc) that rise quickly to the top of the
separation tank The waste particles form a "float" on top of
the tank which is then skimmed off.
