Submerged Anaerobic Membrane Bioreactor Awarded
 London,
UK -- Gut bugs that can turn raw sewage into energy was
among the research projects recognized last week with Royal
Society Awards aimed at supporting and encouraging
innovation. The annual ceremony, organized by the Royal
Society to help researchers commercialize their scientific
ideas, saw Professor David Stuckey win the Brian Mercer
Award for Innovation.
Professor Stuckey received the
grant of £250,000 to develop a revolutionary new sewage
treatment process which will use bacteria that primarily
comes from the human lower intestine to breakdown effluent.
Professor David Stuckey said,
"Current sewerage treatment technology, which uses oxygen to
breakdown waste, is power intensive - using 5 per cent of
all energy used in the UK - and produces thousands of tonnes
of sludge which is difficult to dispose of."
Professor Stuckey believes he has
developed an environmentally sound system which actually
creates energy and clean water, and reduces sludge by 90 per
cent.
The new funding will help
Professor Stuckey to build and pilot a new plant, known as a
Submerged Anaerobic Membrane Bioreactor (SAMBR), which will
be located alongside the Cambridge Treatment Plant. His
technology employs a revolutionary new technique which uses
membranes to filter wastewater out for potential reuse, and
bacteria that doesn’t require oxygen to breakdown waste.
Professor Stuckey says his
bioreactor could be of particular benefit in countries where
water is scarce. He also believes it could be used on a
miniaturized scale, for example to treat waste in blocks of
flats or small urban communities.
“Imagine a day when mini
bioreactors, located under apartment buildings, are able to
convert raw sewerage from flats into valuable methane gas
for use in household heating, and treated water recycled
back to flush toilets. Funds from my award will develop the
world’s first low waste bioreactor which has the potential
to revolutionize the way we deal with effluent,” said
Professor Stuckey.
The Royal Society is an
independent academy promoting the natural and applied
sciences. Founded in 1660, the Society has three roles, as
the UK academy of science, as a learned Society, and as a
funding agency. Up to 150 guests attended the event, which
was held in the Welcome Trust Lecture Hall and chaired by
Sir Peter William, treasurer of the Royal Society.

Eco-Tec Launches Biogas
Purification Technology
 Pickering,
ON -- Eco-Tec proudly welcomed the Honorable Harinder Takhar
Minister of Small Business and Entrepreneurship, to its
event marking the shipment of its first two Biogas
Purification systems. The event consisted of a brief
presentation by Eco-Tec President, Mike Dejak, followed by
an introduction of Minister Takhar who presented Eco-Tec
with a Certificate of Congratulations.
"The growth of Ontario's economy
depends on innovation by our small and medium enterprises so
that Ontario remains competitive on the global stage," said
Minister Takhar. "As a pioneer in the industrial
manufacturing sector that is going global, Eco-Tec is
setting a great example for business of all sizes across the
province."
The biogas purification
technology is used to economically remove hydrogen sulfide
from methane as it is produced. Two recent sales of the
Biogas Purification Systems, one for the treatment of
landfill gas purification, and the other for treating gas
generated through food processing waste by a leading
Canadian food manufacturer-have increased both awareness and
availability of environmental technology.
"We are pleased to be able to
showcase Eco- Tec's continued success in manufacturing
environmental equipment in Ontario, which brings benefits to
the local economy and the global environment," stated Mike
Dejak, President.

TU Delft Tests Windmill for
Seawater Desalination
 Delft,
The Netherlands -- A traditional windmill which drives a
pump: that is the simple concept behind the combination of
windmill/reverse osmosis developed by the Delft University
of Technology (TU Delft) in The Netherlands.
In
this case, it involves a high-pressure pump which pushes
water through a membrane using approximately 60 bar. This
reverse osmosis membrane produces fresh water from seawater
directly. The windmill is suited for use by, for instance,
small villages in isolated, dry coastal areas.
The
combination of windmills and desalination installations is
already commercially available. These windmills produce
electricity from wind power, the electricity is stored and
subsequently used to drive the high-pressure pump for the
reverse osmosis installation. The storage of electricity in
particular is very expensive. Energy is also lost during
conversion.
In the
TU Delft installation, the high-pressure pump is driven
directly by wind power. Water storage can be used to
overcome calm periods. The storage of water is after all a
great deal cheaper than that of electricity.
Robust
The
chosen windmill is normally used for irrigation purposes.
These windmills turn relatively slowly and are also very
robust. On the basis of the windmill’s capacity at varying
wind speeds, it is estimated that it will produce 5 to 10 m3
of fresh water per day: enough drinking water for a small
village of 500 inhabitants.
A
water reservoir will have to ensure that enough water is
available for a calm period lasting up to five days. Three
safeguards (in the event of the installation running dry, a
low number of revolutions or a high number of revolutions)
are also performed mechanically so that no electricity is
needed.
Prototype
The
first prototype has been built and is already working at a
location near the A13 motorway near Delft. This prototype is
to be dismantled and transported to Curacao the first week
of March. There the concept will be tested on seawater.
The
research is being sponsored by Mr Grootscholten,
Aqua-for-All, Hatenboer and SenterNovem.

Making the World’s Water
Supply Arsenic-Safe
 Reston,
VA -- Arsenic poisoning affects nearly 100 million
people living in Bangladesh and West Bengal, India due
to naturally occurring arsenic found in drinking water
drawn from underground sources. While the problem may
seem complex and difficult to address, the solution is
actually easy-to-operate and culturally compatible.
That solution, arsenic
removal units (ARUs), was recently named one of five
finalists for the 2008 Outstanding Civil Engineering
Achievement Award (OCEA) presented by the American
Society of Civil Engineers (ASCE). This year’s
award-winning project will be announced at ASCE’s annual
Outstanding Projects and Leaders (OPAL) Awards Gala on
Wednesday, April 30, 2008, at the Hyatt Regency Crystal
City in Arlington, Va.
“Access to safe drinking
water is something we often take for granted,” said ASCE
President David G. Mongan, P.E., F.ASCE. “This project
not only removes arsenic from the groundwater—making it
safe for human consumption—but it also provides a safe
method of containment for the removed arsenic, one that
does not have a long-term adverse ecological impact.
That kind of contribution to a community’s well-being is
what the OCEA Awards stands for.”
Arsenic is the most toxic
naturally occurring contaminant in groundwater. The ARU
lowers the arsenic concentration from as high as 500
parts per billion to less than 50 parts per billion,
which is the Indian standard of maximum contaminant
level of arsenic in drinking water. Arsenic removed from
groundwater is converted into a low-volume solid waste
and contained in coarse sand filters with minimum
arsenic leaching potential.
Currently, more than 150,000
villagers are using arsenic-safe potable water from ARUs
attached to ground well pumps, which do not require
chemical additions, pH adjustments or electricity. Water
is pumped into the unit—the same way water was
previously pumped from the well—and then it passes
through beads of activated alumina that remove the
arsenic.
A villagers’ committee takes
over ownership and day-to-day maintenance of the ARU
after installation. Each family drawing water from the
ARU pays a monthly tariff of 20 Indian rupees, or 50
U.S. cents, for 40 liters of arsenic-free potable water
everyday—one person can collect their water in less than
three minutes. The findings of the project can be
extended to mitigate similar arsenic crisis in other
countries including Cambodia, Mexico and Vietnam. The
project resulted from a long-standing collaboration
between Lehigh University in Pennsylvania and Bengal
Engineering and Science University in India and was
partly funded by Water For People.
Other 2008 OCEA finalists
include the Mission Valley East Light Rail Transit
project in San Diego; the Pasadena City Hall Seismic
Upgrade and Rehabilitation in Pasadena, Calif.; the new
Tacoma Narrows Bridge in Tacoma, Wash.; and the Woodrow
Wilson Bridge project in the Washington,
D.C-metropolitan area.
Established in 1960 by ASCE,
the OCEA program recognizes projects on the basis of
their contribution to the well-being of people and
communities, resourcefulness in planning and design
challenges, and innovations in materials and techniques.
Selected from a group of 26 entries, the 2008 finalists
are outstanding examples of how civil engineering can
contribute to a community’s economic success, improve
residents’ quality of life and protect public safety.
Previous winners have included the Golden Gate Bridge
Seismic Retrofit in San Francisco, the Saluda Dam
Remediation project in Columbia, S.C. and the
Rion-Antirion Bridge over Greece’s Gulf of Corinth.

Hot Messages from the Help Forum

Ms. Velasco needs help with
reverse osmosis:
In using the RO membrane
projection system, for example, ROSA, permeate: 34.72gpm,
TDS - 17225ppm, 50% recovery, BW30-400, 2 vessels x 4
elements, feed temp: 25degC, SDI < 3.
Projecting the above values
will not produce warning, means that the system is good. But
when I increased the number of vessels (3 vessels x 4
elements) warnings like maximum element recovery has been
exceeded comes out. Why?
Isn't it that distributing
the flow into 3 vessels will lessen the load on each
membrane thus extending the lifespan of membranes?
I would appreciate your help.
