Solar
Panels Power Superfund Site Groundwater Cleanup
 Sacramento,
CA -- The U.S. Environmental Protection Agency’s Jared
Blumenfeld, U.S. Congressman Mike Thompson and Linda Adams,
Secretary of the California Environmental Protection Agency
today hosted a press conference and media tour to provide
details about recent exciting energy conservation and
cleanup accomplishments at the Frontier Fertilizer Superfund
site in Davis, California. An innovative electrical
resistance heating system partially funded by the American
Recovery and Reinvestment Act officially went online today
and will reduce the projected timeline to cleanup the site
from 150 years to 30 years.
“For the first time ever, solar
will provide all of the power for a Superfund groundwater
cleanup,” said Jared Blumenfeld, EPA’s Regional
Administrator for the Pacific Southwest. “Our goal should be
to clean the environment in the greenest way possible—and
this new treatment plant sets the benchmark for future
actions.”
More than $2.5 million dollars in
stimulus funding has gone to recent improvements at the
site. By installing the solar panels and starting the new
system, the site will lower overall energy costs by $15,000
a year and reduce CO2 emissions by more than 54 metric tons
a year. It will also speed the cleanup by an estimated 120
years.
“I am pleased with the impressive
progress that has been made in the cleanup of the Frontier
Fertilizer Superfund Site,” said Rep. Thompson. “Gains of
this magnitude would not have been possible without the
innovative use of solar panels to power the cleanup. These
are exactly the kinds of smart, targeted investments that
will help create jobs, strengthen our economy, and position
our community as a leader in the clean energy industry.”
“It’s very rewarding to be able
to use the latest green technologies to accelerate the
cleanup of toxic sites in communities” said Linda Adams,
Secretary of the California Environmental Protection Agency
(Cal-EPA). “It means that Cal EPA can work more efficiently
at converting contaminated properties into productive sites
for the local community. Frontier Fertilizer is a prime
example of using green technology to green up
neighborhoods.”
Electrical resistive heating is a
technology sometimes used to cleanup sites when conventional
methods will not work. The heating system includes 236
heating electrodes that will heat the soil and groundwater
to the boiling point of water. Extraction wells
strategically located in and around the heated areas will
collect gas and liquids generated by the heating system.
Extracted gas and liquids are treated with granular
activated carbon. Twenty-seven temperature-monitoring wells
will be used to monitor the below ground operation.
EPA first installed limited solar
panels at the Frontier site in 2007. The initial system
helped to partially offset the electrical power needs for
the groundwater treatment system but could not fully power
the site. In 2010, $350,000 in Recovery Act Funds were used
to expand the solar system, which now provides 100% of the
power for the groundwater treatment system.
The new solar panels cover half
an acre and have resulted in a ‘green’ method that generates
plenty of solar energy and will off-set non-renewable energy
use. The expanded solar panel system was installed by a
small, local business. To further green the site, the
project team is also evaluating options for the reuse of
treated groundwater for irrigation of City and Caltrans
properties.
The Frontier Fertilizer site was
first developed in the 1950s to store agricultural
equipment. Operations in the 1970s and 1980s consisted of
storing, mixing and delivering pesticides and herbicides.
For years since, toxic chemicals including pesticides and
herbicides have been leaking into soil and groundwater, the
primary source of drinking water in the area.

University Scientists Behind Safer Drinking Water
 Belfast,
Ireland -- Pioneering technology by scientists at Queen’s
University Belfast, which is transforming the lives of
millions of people in Asia, is now being used to create
safer drinking water in the United States.
The award-winning system —
Subterranean Arsenic Removal — removes arsenic from
groundwater without using chemicals. It was developed by a
team of European and Indian engineers led by Dr Bhaskar Sen
Gupta in Queen’s University School of Planning, Architecture
and Civil Engineering.
The technology, based on the
principle of oxidation and filtration processes, is already
in use in six plants in West Bengal.
And the technology has now been
successfully tested in the United States, in a rural
community outside Bellingham, in Northwest Washington State,
where high levels of arsenic in the water had previously
caused challenges for local residents.
Jeremy Robinson, a member of the
Washington State installation team, said: “We first read
about the SAR technology on Wikipedia. Initially, it seemed
too good to be true. Arsenic is a significant problem for
many of the wells in our area. None of the conventional
approaches for arsenic treatment have worked well for us.
But, once we recognized the advantages and elegance of the
SAR approach, we started preparing to test it here.
"With the generous help offered
to us by Dr. Sen Gupta and Queen’s University, we are now
under way. Our early results have been very promising. We
started the trial in January, on an abandoned well with
alarmingly high arsenic levels. After three weeks, the
arsenic level had dropped substantially. And now, after
seven weeks, we are seeing arsenic levels at or below the US
Environmental Protection Agency limit."
Dr Sen Gupta, who visited
Washington State to oversee the installation, said: “I’m
delighted that the Washington State plant testing has gone
to plan. The key aspects of this life-changing technology
are its affordability and simplicity of installation and
operation. The cost of setting up a plant to produce up to
6,000 liters of water a day averages under £2,500 ($4,000) —
less in the developing world — and the operational cost is
£14 a month ($20.
“The estimated life of each plant
is about 20 years without any mechanical maintenance, and
the system is operated, quite simply, by the pressing of an
electrical switch.”
The technology has already
attracted interest from other parts of the United States,
and plans are now advanced for SAR plants to be set up in
Cambodia, Vietnam and Mexico in the next six months.
The work of Dr Sen Gupta’s team
has won accolades from around the world. In November Queen’s
University was awarded the prestigious Times Higher
Education Outstanding Engineering Research Team of the Year
title.
The judges said: “Engineering at
its core is about solving critical problems. The team from
Queen’s has exemplified this, finding an innovative solution
to overcome arsenic contamination of groundwater and thus
improve the quality of life in rural communities.”
Dr Sen Gupta was also awarded the
St Andrews Prize for the Environment and the World Bank
Innovation Fair Championship in Cape Town in 2010.

KMS Provides Puron MBR
Modules for Egyptian Resorts
 Aachen,
Germany -- Tam Environmental Services has chosen the
Koch Membrane Systems trading division of Koch Chemical
Technology Group Ltd. to provide Puron® membrane
bioreactor (MBR) modules for the wastewater treatment
plant at new tourist resorts in Sharm El Sheikh, Egypt.
The MBR will be used to treat municipal wastewater,
which will allow effluent to be reused for irrigation
and conserve the region’s scarce water resources.
Al Montazah Company for
Tourism and Investment is developing the infrastructure
for new holiday resorts in an arid area with limited
drinking water supplies located on the Sinai Peninsula’s
southern tip along the Red Sea coastal strip. TAM
Environmental Services from Cairo was assigned to build
an onsite wastewater treatment plant that has a small
footprint, is less visible, provides effluent water
suitable for reuse, and is modular to accommodate future
expansion. While other technologies were reviewed to
meet the requirements, MBR was the most feasible
solution.
The plant’s first phase is
designed for an annual average flow of 5,000 m3/d.
Start-up of the MBR with the Puron PSH 1500 modules is
scheduled for end of 2011.
“We have been using RO
membranes from Koch Membrane Systems for many projects
in the region”, says Said Mohamed el-Said, General
Manager of TAM Environmental Service. “Besides the high
quality of the products, we are always extremely happy
with the first-class service and engineering support
that they provide. When we learned about the robust
Puron membrane system with its unique features, it
became clear that it would be the first choice for this
type of application.”
The demand for Puron MBR
technology in the Middle East and North Africa region
continues to increase steadily. A 2,000 m3/d
installation had just been commissioned at end of 2010,
treating the municipal wastewaters of a Saudi Arabia
refinery.

Mr. Boyles needs help with
ammonia results:
We are analyzing nitrogen
species throughout our plant to generate a nitrogen budget
for the process. We sometimes get higher ammonia results
than TKN results for the same sample, whether it is
influent, effluent, or other streams.
We distill and titrate for
ammonia, and do TKN with H2SO4/Hg digestion and run the
salicylate method on an autoanalyzer (Lachat). The nitrates
are low (generally below a couple ppm) and TKNs are in the
20-30 ppm range. Samples with high TDS such as influent or
filter press runoff are particularly off.
Running TKN at a dilution or
titrating TKN digests instead of the Lachat analysis give
the same results. Anyone else out ther have this kind of
experience?
Appreciate any help you can
give us!
Thanks,
Matt Boyles
