Detecting Leaks in Chicago
Watermain
Huntsville, AL -- ADS LLC
announced today that The Pitometer Group of ADS has recently
been successful in locating a leak for the City of Chicago
in a 36" PCCP watermain. As service providers to the City of
Chicago for over 40 years, ADS is now able to detect leaks
in pipes as large as 60" thanks to a new large diameter leak
detection technology.
This new technology pinpoints
leaks in large diameter mains without the set-up intensive,
and intrusive, techniques used by other technologies. ADS is
the only authorized service provider of this technology
which utilizes the Echologics LD Leakfinder for large
diameter leaks.
ADS was asked to locate a
potential leak on a 36" concrete main on September 11, 2007.
The leak was showing in a basement of a nearby building.
Echologics Hydrophone sensors were placed on the hydrants
off the 36" main at a distance of 829 feet. After
implementing the signal processing algorithms, the leak came
up instantly, and was located to within inches. The leak was
found to be located at a concrete to iron adaptor with a
torn gasket.
ADS has proven they can find
leaks in large pipes without inserting equipment into the
pipe. The accuracy of this technology in pinpointing the
leak is also superior to other technologies. ADS provides
leak detection services to the City of Chicago as part of a
Hydraulic Engineering Services contract that also includes,
loss of head tests, flow and pressure measurements, flow
profiling, hydraulic gradients, fire flow tests and valve
exercising.

Biogas Purification for RGMRM
Project
 Pickering,
Canada -- Eco-Tec is proud to announce that it has recently
been awarded the contract for a biogas purification system
by Régie de gestion des matières résiduelles de la Mauricie
(RGMRM) of Quebec. The integrated process includes the
capture, purification and use of biogas as an alternative
energy source for greenhouses.
"Hot
house tomatoes are not the only beneficiary of biogas
purification technology, and we are pleased to be a part of
RGMRM's long-term plans to reduce greenhouse gases." Stated
Carmine Fontana, Eco- Tec's VP Business Development.
RGMRM
is a municipal organization that operates most of the
municipal landfills in the Mauricie region in Quebec. The
landfills, such as the Saint-Étienne- des-Grès landfill and
the Trois-Rivières landfill have life spans of over 60
years. Each year one landfill will generate 18,000,000 m3 of
biogas, the energy equivalent of 9,000,000 m3 of natural
gas. RGMRM has developed and implemented plans to capture
the biogas and use it in sustainable development projects
that are designed to reduce greenhouse gas (GHG) emissions
by approximately 135,000 tons of CO2.
RGMRM's projects have three major advantages: they provide
plans to use an environmentally sustainable process to
manage the entire life cycle of buried waste; they allow a
renewable energy generated from biogas to replace a fossil
fuel; and the projects are becoming sources of revenue for
RGMRM and the municipalities that use and sell the biogas.
Biogas
is a mixture of methane (CH4) and carbon dioxide (CO2) and
is often contaminated with toxic quantities of hydrogen
sulfide (H2S). Eco-Tec's biogas purification system was
selected for its proven, highly efficient technology. The
system was designed to integrate into RGMRM's process, that
includes gas conditioning through the removal of water,
sulfur and H2S. Using a patented, high efficiency gas-liquid
contacting process, H2S is absorbed and the gas is purified
for use in power generation facilities, and other heating
applications such as heat for tomato greenhouses.

Europe : IFAT 2008 Grows and
Grows
 Munich,
Germany -- At IFAT, the 15th International Trade Fair
for Water – Sewage – Refuse – Recycling, which takes
place from 5 to 9 May 2008 in Munich, the visitors can
look forward to an impressive range of innovative
solutions and new technology for implementing practical,
cost-efficient solutions, plus a broad spectrum of
services for the sector.
The most important
environmental trade fair in the world will be even
bigger in 2008 than at the last event in 2005. In 2008,
the exhibition space is expanding to 192,000 square
metres, which is 22,000 square metres more than at IFAT
2005. This represents an increase of 13 percent. An even
bigger rise has been noted in the space booked by
international exhibitors. This has risen by 18 percent.
IFAT is the world’s most
important trade fair for the environment and waste
disposal. With the expansion of the theme of energy
generation from waste products, the subject of biogas
will move more into the spotlight. The fair is thus
responding to current trends in the market and
underlining its role as a leading international event
for the sector.
The attractions at IFAT 2008
are rounded off with a programme of trade conferences,
symposia and forums exploring new directions for the
future, and events focusing on flood protection and
disaster prevention and control. In the forums
exhibitors and associations will be putting on lectures
and panel discussions on current product developments,
trends and market analyses. These events are an
excellent opportunity for gathering new ideas, updating
knowledge and forging new business contacts.
About IFAT
IFAT is the world’s most
important trade fair for the environment and waste
disposal – for water, sewage, refuse and recycling. In
2005 the event attracted a new record number of
participants with 2,223 exhibitors from 36 countries and
109,000 trade visitors from 166 nations. IFAT 2008,
which takes place in Munich from 5 to 9 May 2008, offers
an attractive exhibition programme: innovative solutions
and state-of-the-art technology for practical,
economical operations, a broad range of professional
services in the area of water, sewage and refuse
management and numerous attractive information events.

Mr. Losey wants to find help for his DAF clarifier:
We operate an activated
sludge system that uses a DAF clarifier to remove solids
prior to discharging to the city. The DAF receives flow from
the aeration basin at a rate of 280 gpm with loadings of
around 5,000 ppm.
We operate two air chambers
on the DAF with a total of 230 gpm of recirculated flow
(this totals 510 gpm). The size of the DAF is approximately
20,000 gallons.
I am trying to determine
whether the size of this DAF is to large and whether that
can hurt its efficiency. Also, I am looking for some
information on the design an operation of DAF Clarifiers.
Does anyone here have any
recommendations for this information?

Mr. Edwards needs help
upgrading his RAS system:
Because I have chosen to
upgrade my POTW's RAS system from fixed to flow paced RAS, I
have to file a new ROWD with my Regional Board. (Doing
things more efficiently requires a new permit). I think most
of us know that flow pacing minimizes fluctuations in the
F/M ratio.
There isn't much I can do
about the drop off in CBOD overnight but slowing the return
rate will go a long way towards smoothing things out,
especially since my typical inf. flow is 300% of that in the
wee hours.
I need some documentation for
reference in my application 'cause I know those pesky folks
who issue that permit I frame on my wall will feel better if
I find somebody with PHD after their name to refer to when I
explain why to them why this improvement will enhance plant
performance.
Don't you just love
government?

The Inside Story on
Moisture-Cured Coatings
It’s common knowledge
that polyurethane coating technology is an excellent
choice for demanding exterior applications such as
bridges, stadiums and other large structures. But
when maintenance was required inside the Hammond
Water Filtration Plant in Hammond, Ind., a
moisture-cured polyurethane system proved to be the
only way to go to coat more than 35,000 square feet
of piping and valves...(more) |
