WERF Donates Money-Saving Biosolids
Patent to the Public
Alexandria, Va. --The Water
Environment Research Foundation (WERF) on Jan. 28 donated to the
public a patent they were issued for a cost-effective process that
will help utilities achieve the highest standards for biosolids. By
achieving these high standards, Class A for pathogens, jurisdictions
will have the greatest flexibility in distributing their biosolids
for use as a soil amendment.
By donating the patent to the public,
the technology is protected for use by the water quality community.
Through these efforts, WERF continues to support innovation and
application of technology to complex water quality problems and
encourage the next generation of engineers and scientists.
"As the lead investigator in
this joint research effort, EBMUD supports the decision to donate
the patent to the public domain," said David Williams, Director
of Wastewater at EBMUD. "It is our desire to see that research,
which produces technological innovations, be widely available and
distributed so that the greatest public good can be achieved. We are
hopeful and very pleased that through the release of this patent on
our thermophilic digestion process, we are helping to better protect
public health and environment."
The patent evolved from a
WERF-sponsored project, Pathogen Destruction Efficiency in High
Temperature Digestion, that developed a high-temperature anaerobic
digestion process that can provide a low-cost method for achieving
Class A pathogen standards in biosolids at both large and small
wastewater treatment plants (WWTPs). The WERF board and the
contractor for the project, East Bay Municipal Utility District
(EBMUD), have agreed to officially donate the patent to the public.
Class A pathogen standards apply to
biosolids that are sold or given away in containers or applied to
lawns or home gardens. In addition, many regional and local
jurisdictions are now requiring that all land applied biosolids to
meet federally regulated Class A pathogen standards.
The official dedication ceremony took
place Jan. 28, 2003 at the board meeting of EBMUD in Oakland, Calif.
WERF Board Chair Steven T. Hayashi, General Manager & District
Engineer of Union Sanitary District, Union City, Calif., was on hand
to present the plaque.
"An important aspect of WERF's
mission is to provide publicly accessible water resources
research," said Hayashi. "The dedication of the patent
process to the public good will ensure that public agencies and
others have free access to this process that allows biosolids to be
managed responsibly and cost-effectively."
The final phase of this project,
currently in progress, is aimed at demonstrating the effectiveness
of the process at full-scale at one EBMUD's plants. The key
objective will be to obtain a process to further reduce pathogens -
those processes that EPA designates as providing Class A biosolids
equivalency for full-scale thermophilic anaerobic digestion process.

Conference
& Exhibition
Water & Wastewater
Europe 2003
When: March 4-6,
2003
Where: Acropolis Congress Hall - Nice, France
A major new conference and
exhibition totally dedicated to European water issues. This inaugural
event will be the first of a high-level series that will be held
within Europe annually.
Water
& Wastewater Europe 2003 will bring together experts from major
players in the industry, including both the public and private
sectors, to discuss the region's most serious water challenges -
Impact of the Water Framework Directive, Water Production &
Quality, Cross Border Pollution, Privatization Issues, Wastewater
Treatment and Sludge Management.
Representatives from the
European Commission, financial institutions, national governments,
international organizations and leading water companies will share
their insights on strategic policy and technical issues during the
conference.
This series of regional
events starts at an important time. Many European nations face serious
financial and technical challenges in meeting the Water Framework
Directive deadline by 2015. How will this EU directive affect
industry? Water shortages in southern Europe are resulting in the
construction of more desalination and water reclamation plants to
produce alternative water supplies. Will this trend further reduce
water production costs for arid regions?
Water & Wastewater
Europe 2003 will cover these issues and more that are equally critical
to the region's environmental health and economic prosperity. We look
forward to welcoming you to the Acropolis Congress Hall in Nice,
France in March.

Sanitary
Design
GEA Filtration Improves the ROI in
Reverse Osmosis
Hudson, WI -- GEA Filtration
introduces sanitary reverse osmosis plants in an 8"
spiral-wound configuration. The new sanitary 8" design offers
the same modular, cost effective plant construction and operating
advantages as the smaller diameter spiral plants that GEA Filtration
has delivered over the past 20 years with the added advantages of
even more compact design, lower capital cost and reduced membrane
replacement cost with no adverse effects on plant cleanliness or
sanitation.
The
plants are constructed to the same exacting standards that have
become the trademark of GEA Filtration quality Membrane Filtration
plants, but the membrane area is delivered in the larger 8"
diameter sanitary, spiral wound format and is housed in 8"
sanitary vessels. The increased membrane packing density allows for
an added level of compact design, saving valuable floor space.
Additionally, the capital cost is
reduced by the scale economics of the sanitary 8" spiral. The
scale economics also contributes to a reduced membrane replacement
cost, which represents a large portion of the total operating cost
in a Reverse Osmosis plant. Operating costs are further reduced by
the improved compact design and reduced plant hold-up volume. This
results in reduced water consumption and the associated waste water
treatment costs as well as a reduction in the consumption of CIP
chemicals.
The plants are constructed to 3A
sanitary standards for compliance with USDA and local regulatory
health agency requirements. Exhaustive cleaning and sanitation
trials on several commercially delivered plants have verified that
plants operate with no compromise to cleanliness and sanitation.
With several plants now delivered and in operation and several more
in the pipeline, sufficient demand has been created to ensure that
membrane elements in the 8" sanitary configuration are widely
available from a number of manufacturers and can be supplied
directly from GEA Filtration stock.

Blending
WWTP into Local Landscape
Earth Tech Recognized by ICE
LONG BEACH, Calif. - January 21, 2003
- Earth Tech was recognized by the Institution of Civil Engineers
(ICE) with the association's Edmund Hambly Medal for the company's
work on the $40 million Scarborough Urban Waste Water Treatment
Directive (UWWTD) plant, in North Yorkshire, England.
The Edmund Hambly Medal is an award
for the creative design of an engineering project that makes a
substantial contribution to sustainable development. The award
emphasizes the important contribution that civil engineering makes
to the well being of mankind and the environment.
The new wastewater treatment plant
for Scarborough was a key element of the Yorkshire Water Company's
CoastCare program aimed at providing the highest levels of sewage
treatment along Yorkshire's coastline. The plant was initiated in
order to comply with the European Union's UWWTD. Earth Tech was
responsible for the feasibility design, obtaining planning
permission, project management and supervision of construction. The
site that eventually gained planning approval was located along the
Heritage Coast, near the North York Moors National Park.
In order to blend the wastewater
treatment works into the local landscape, the development was
designed to resemble a traditional farm, with all the treatment
processes either contained within the buildings or situated out of
sight within a central courtyard. A further environmental benefit of
the plant is the pioneering use of the NViro sludge treatment
process to produce a pasteurized end product, which has a beneficial
use as a lime rich agricultural fertilizer meeting U.S. standards
for sludge treatment, which are in excess of the European
requirements.
The Institution of Civil Engineers is
an independent engineering institution. It was established in 1818,
and today represents over 80,000 professionally qualified engineers
worldwide and the civil engineering industry. Its principal
membership is in the United Kingdom but the ICE also has an
expanding international membership; with interests in China,
including Hong Kong, Russia, India and 140 other countries.
Founded in 1970, Earth Tech ( www.earthtech.com
) is an international provider of global water management and
transportation, engineering and environmental services. Earth Tech
is headquartered in Long Beach, Calif., and employs more than 8,000
people in nearly 200 offices worldwide.

We cook and process fresh corn to
make corn tortillas and tortilla chips. Our process waste water
contains high levels of BOD COD and TSS.
Is there an "industry
standard" method of reducing these offenders? How are other
Tortillarias dealing with this problem?

I am searching for a treatment method
for Pan Bottom effluent generated from a soap industry. The
Pan Bottom effluent contains unreacted fatty acids, mud, brine and
soap from the pan. I a batch process 6 cubic meters of
effluent is discharged every week at 90 degrees C.
I have managed to remove soap by
cooling and remaining liquid has high COD value. TDS is also
high. Once coagulated using alum and Nalco 7751 it gives a
clear liquid.
