Dr. Todd wins Buckminster Fuller Challenge Award

WOODS HOLE, MA -- John Todd Ecological Design, Inc. (JTED) a leader in natural wastewater treatment systems, announced today that its founding principal Dr. John Todd was awarded the first-annual Buckminster Fuller Challenge Award with his submission entitled “Comprehensive Design for a Carbon Neutral World: The Challenge of Appalachia”.

The Buckminster Fuller Institute panel of internationally esteemed advisors/jurors issued a statement praising Dr. Todd’s strategy saying the work “best embodies the bold, visionary approach to large-scale societal transformation pioneered by Buckminster Fuller.”

Dr. Todd invented the Eco-Machine™ for the treatment of sanitary and industrial wastewater with a focus on water reuse and energy efficiency. JTED has designed and installed innovative ecological wastewater treatment systems throughout the world for the past 20 years. Recognized with three merit awards by the U.S. Environmental Protection Agency, Dr. Todd was named among the greatest inventors of the 20th Century by David Brown in his book Inventing Modern America.

Jonathan Todd, President of JTED and Dr. Todd’s son, said the Buckminster Fuller Award is “one of the most meaningful and significant” his father has received. He added, “In the fast-growing ecological systems design world, being chosen to receive this prestigious award gives us all a renewed sense of optimism.”

Innovative Water-Leakage Modeling Software

EXTON, PA -- Bentley Systems, Inc. today announced the latest version of its Darwin Calibrator module featuring water-leakage modeling capabilities. The new version of the module, which is included in WaterGEMS V8 XM and available for WaterCAD V8 XM, provides a cost-effective way to estimate the location and extent of hidden leakage in underground pipes.

The Ontario Sewer and Watermain Construction Association in Canada reported that approximately $1 billion worth of clean drinking water disappears into the ground every year from deteriorated and leaky municipal water pipes. The innovative methodology behind the new Darwin Calibrator was developed by Bentley and United Utilities Water (UUW) PLC.

Commenting on the key benefits of the new Darwin Calibrator technology, Dr. Zheng Yi Wu, Bentley director of applied research in engineering optimization, said, “Existing leak-detection techniques, such as step-testing or acoustic devices, require a lot of apparatus and personnel. As a result, they are very time-consuming and costly. The new leakage-detection feature of Bentley’s enhanced Darwin Calibrator identifies the locations and sizes of the leakage holes, emulated as emitters that allow water to spurt and seep out at different rates depending on prevailing pressure.”

The new version of the Darwin Calibrator was previewed earlier this year by more than 60 water professionals attending Bentley’s Water Loss Seminar and Workshop in Marbella, Spain. At the seminar, Mark Wheeler and Muhamed Hayuti, both of Atkins, the largest engineering consultancy in the United Kingdom, presented benchmark studies on leakage hotspot prediction and water network models conducted in coordination with Paul Sage, modeling development manager for UUW. The studies demonstrated a successful modeling approach for detecting unreported leakage hotspots using WaterGEMS’ leakage-detection capabilities and the newest version of the software’s Darwin Calibrator module.

Commenting on the studies, David Turtle, leakage and demand strategy manager for UUW, said. "We consider the leakage-detection optimization model developed in collaboration with Bentley to be a valuable and important tool in reducing leakage and achieving the annual targets that UUW agreed to with the U.K.’s water-industry regulator, OFWAT. A particular advantage of this technique is its ability to identify hard-to-find leaks.”

AECOM completes acquisition of Earth Tech

LOS ANGELES, CA -- AECOM Technology Corporation, a leading provider of professional technical and management support services for government and commercial clients around the world, announced today that it has completed its acquisition of Earth Tech, Inc., a business unit of Tyco International Ltd.

Earth Tech provides consulting, engineering and design, build and operate (DBO) services to waste/wastewater, environmental, transportation and facilities clients globally.

With the acquisition of Earth Tech, AECOM increases its global presence, particularly in the Americas, Europe, Australia and Asia. AECOM also significantly strengthens its water and wastewater business, while augmenting its leadership position in the environmental, facilities and transportation sectors.

“We are delighted to welcome Earth Tech into the AECOM family,” said John M. Dionisio, AECOM president and chief executive officer. “This transaction, which expands our workforce to more than 40,000 professionals around the world, enhances our ability to take advantage of the growing business opportunities that exist in our global end markets. We expect this transaction to benefit our clients, employees, and shareholders.”

AECOM has also completed the divestiture of certain Earth Tech businesses that do not align with its strategic plans and core businesses. Concurrent with the close of the purchase of Earth Tech, AECOM divested Earth Tech’s Water & Power Technologies (WPT) and North American Contract Operations (NACO) businesses and its Mexican operations.

The value of the divested WPT, NACO and Mexico assets noted above, along with the value of certain assets that have been carved out of the sale transaction with Tyco, represent a total of $175 million of the original $510 million transaction value. There remains approximately $50 to $60 million of assets that will be held for sale by AECOM until sale documentation is finalized, all required consents are received and the transactions can be closed.

Algae Jet Fuel Makes Splash at Air Show

Mesa, AZ -- Researchers Qiang Hu and Milton Sommerfeld from ASU’s Department of Applied Biosciences recently flew to London to share their findings and research on the application of algae-based oils for creating biofuels at the Farnborough International Air Show.

The exhibit was part of a collaboration and ongoing relationship between the researchers and aviation giant Boeing.

While many exhibits showed off the latest improvements on turbines and designs for commercial aircraft and jet fighters, the researchers ended up stealing the show and attracting numerous visitors to their booth.

The star attraction of the Boeing exhibit was a 75-gallon tank of bright green algae.  The tank was, in fact, a bioreactor – a “feeding ground” container that promotes accelerated algae growth. The exhibit was the high note of a one-year relationship between the ASU researchers and Boeing.

The company has committed a $225,000 grant to support ongoing algae research at ASU, and to provide three scholarships for graduate students.

“The experience was very positive, because most shows are too technical for the public,” Hu says. “With the live algae, we can explain to children and families how algae grow, and how we extract the oil and convert it to jet fuel.”

Hu and Sommerfeld were a big hit with children – and they also attracted the attention of aviation business leaders and engineers. The two researchers earned an immediate nod from Boeing to keep a presence at the air show.

“Not many people knew about ASU,” Sommerfeld says. “However, they expressed great interest in the growing algae and the potential it has for production of oil that can be used for transportation fuel, especially since using algae eliminates the problem associated with converting crop foods to fuel.”

The use of algae for multiple applications has several appeals, including:

  • Algal oil is very similar to other vegetable oils, but its yield is projected at 100 times that of soybean per acre of land on an annual basis.
  • Unlike other plants, algae reproduce quickly without roots and stems, and they never go dormant.
  • Algae can remove carbon dioxide from power plant emissions and recover nutrients from wastewater.

According to Hu, the technology to help algae reproduce effectively is still five years away.  “The critical issue is the biomass feedstock, not oil conversion,” Hu says. “To bring the cost down we need much more breakthroughs and innovations. Bioreactors are expensive at this stage. We need a cost-efficient way to sustain high growth.”

Once algae reach a critical mass, traditional methods can be used to extract oil from the plants. In turn, these oils can be refined into gasoline, biopolymers and jet fuel.  So what’s next in the process of making jet fuel from algae?

“Our effort will be geared to developing a pilot-scale facility that will enable us to integrate various components of oil production and evaluate the economics of the process,” Sommerfeld says. “Since ASU is a leader in developing approaches to sustainability, it could, for example, incorporate the use of algae-produced biofuels on some of its vehicles over the next several years as our production increases.”

Hu and Sommerfeld are the co-directors of the Laboratory for Algae Research & Biotechnology (LARB) at the Polytechnic campus.  The duo has been able to take their combined 40-plus years of research with algae and apply it to use in air and water remediation, alternative fuels and animal feed. Considered a nuisance by many, algae have the potential to someday become an environmentally sound substitute for crude oil.

Nasir wants with piping and valves on aeration tank:

How usually are air blowers connected to an above ground, open to atmosphere, aeration tank?

At present, our main blower pipe is connected from the tank bottom outside through a valve. Due to high temperature and vibration, we suffer leakage from the valve side when the blowers are off.

I am thinking to drain out the tanks and connect the main air feed pipe from inside the tank using flexible pipe. Could you please advise me in this?   (Click here to post a reply)
