Auricchio T., Rankhambe P., Sharma K., Nectar Partners, US

A Clean Tech Economy poster demonstrates the visual impact of economic development efforts to build and grow a clean tech economy in Central Upstate New York, also known as the Creative Core Region. Recently recognized [...]

The Clean Energy Landscape- Linking Cyberspace with Real World Impact

Wise A., National Renewable Energy Laboratory, US

NREL has launched a new open platform (http://openei.org/cee) that will help us to understand and engage the clean energy marketplace. We have designed an open source interface called the Clean Energy Economy Gateway that solicits [...]

FlexEnergy: Using Waste Fuels to Eliminate 25 Times the GHG Effect of CO2

Prabhu E., Fukumoto P., Luedde B., FlexEnergy, LLC., US

The Flex Powerstation is the cleanest power platform in the world. The Flex oxidizes gases especially weak and waste gases previously unusable to produce clean, green electricity. Today’s emissions problem becomes a green energy source. [...]

Agriculture Industry Sees Green in Wireless Technologies

Ersavas B., Comucicnao, Inc, US

While green is certainly considered good, applying advanced wireless technologies across the agriculture industry’s food chain is great. Bringing mature machine-to-machine (M2M) wireless communications to this broad industry – which includes growers, greenhouses, transporters and [...]

Precipitation, Adsorption and Inhibitory Effects of Nano Copper in Wastewater Activated Sludge

Smeraldi J., Rajagopalan G., Cooper W.J., Hosseini T., Rosso D., University of California Irvine, US

Objective of this study is to compare the fate, removal and inhibitory effects of nanocopper (oxide) with ionic copper in activated sludge. Impacts of functionalization (complexation) of nanocopper as well as the mechanism of nanocopper [...]

Using Zeta Potential to Optimize the Water Clarification Process in a Full-Scale Water Production Facility

Nobbmann U., Gertig K.R., Billica J.A., Morfesis A., Malvern Instruments, Inc., US

Zeta potential provides a measurable value to monitor optimal water clarification capabilities. The magnitude of the zeta potential value indicates the repulsive interaction between particles; a zero zeta potential means that the conditions for the [...]

Analysis of Membrane Filtration Efficiency in Removal of Metal Oxide Nanoparticles from Aqueous Nanoparticle Suspension in the Presence of Coagulation Pretreatment

Surawanvijit S., Kim M., Cohen Y., University of California, Los Angeles, US

The introduction of nanoparticles (NPs) into aqueous environment is expected to rise with increased manufacturing and use of nanoparticles. There is a need to identify efficient and methods for NP removal and such methods must [...]

New UV Technology for Point-of-Use Water Disinfection

Bilenko O., Bilenko Y., Shturm I., Bilenko O., Bilenko Y., Shatalov M., Gaska R., Sensor Electronic Technology, Inc., US

We will report on a record performance of an all-LED point-of-use water disinfection system that utilizes our deep UV LED lamps with peak emission wavelengths in the range from 270 nm to 280 nm. Results [...]

Innovative Cost-effective Pre-treatment for Desalination

Lean M.H., Seo J., Kole A., Volkel A.R., Chang N., Hsieh B., Melde K., Palo Alto Research Center, US

This paper describes an innovative technology to pre-treat feed water for desalination. An inline coagulation-flocculation-separation (CFS) system is detailed that does not require filtration or sedimentation. Advantages include: scalability, modularity, rapid processing, low energy, and [...]

Efficiency’s Last Frontier: Reflective Building Surfaces

Wiig H.C., State of Hawaii Energy Office, US

Lawrence Berkeley Laboratory scientists hold that if the world’s urban areas were highly reflective, global warming would be delayed by eleven years. However, America’s building energy codes do not cite reflective surfaces as key paths [...]
