Biomass Power Generation Using Liquid Tin Anode SOFC

Bentley J., Tao T., CellTech Power LLC, US

Currently biomass contributes only 1% of U.S. electric power despite available resources to provide over 20%. Barriers to increased use of biopower include low efficiency of current generators, high capital cost, low fuel energy, feedstock [...]

The Separation of Hydrocarbons from Sand Using Ionic Liquids

Painter P., Miller B., Lupinsky A., Williams P., Penn State University, US

The problem that this work addresses involves the separation of oil, bitumen or tar from sand or other types of mineral matter. The processes presently used to separate or extract hydrocarbons from sand are expensive, [...]

Efficiency of Point-of-Use Water Disinfection Using Deep UV Light Emitting Diode Technology

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

We present results of microbial disinfection of E.coli bacteria in water using Point-of-Use UV light-emitting diode (LED) chamber. A set of four UVCLEAN LED lamps was used to produce UV radiation at 272-273nm. More than [...]

Enhanced Sludge Reduction Using External Bioaugmentation at a Full-Scale Municipal

Shcici R., Newbold A., In-Pipe Technology Company, Inc., US

One the biggest burdens facing municipal wastewater treatment plants are the expenses of hauling and disposing of residual biosolids, or sludge. In 2007, United States municipal wastewater treatment plants produced about 7.7 million dry tons [...]

Comparative Analysis of the Glendale Advanced Wastewater Treatment Plant in Lakeland, FL Using Bioaugmentation

Schici R., In-Pipe Technology Company, Inc., US

The City of Lakeland, Florida selected bioaugmentation in 2001 to treat odor and corrosion in a partial section of the collection system. The technology was in place within the sewer system for approximately six months [...]

Removal of Selenium from Aqueous Solutions Using Magnetite Nanoparticles as Adsorbent

Wei X., Bhojappa S., Lin L.-S., Viadero R.C., SUNY Institute of Technology, US

Selenium (Se) is an emerging contaminant for many regions worldwide especially for areas impacted by past or current mining activities. The objective of this study was to evaluate the effectiveness of synthesized magnetite nanoparticles as [...]

Innovative Technology for Selective Contaminant Removal

Lean M.H., Chang N., Seo J., Kole A., Hsieh H.B., Melde K., PARC, US

This paper describes a two-stage water treatment technology for removal of dissolved contaminants that is relevant to many water matrices. Removal is achieved by adapting conventional adsorption, coagulation and flocculation, or lime softening and/or soda [...]

The Intersection Between Water Scarcity and Renewable Energy

Muys Jr. J.C., Karp J.M., Hildebrand Jr. V.P., Sullivan & Worcester LLP, US

The starting point for any discussion of the intersection between water scarcity and renewable energy is the now generally-accepted correlation between climate change and water resource impacts, which is creating further imperatives for both reduction [...]

The Effects of Bioaugmentation in Collection System

Newbold A., Dickerson R., Kelter M., In-Pipe Technology, US

The wastewater treatment plant in the Town of Orange Park, Florida was challenged to meet a new discharge permit issued by the Basin Management Action Plant (BMAP) for the lower St. John’s River that was [...]

Managing Your Environmental, Health & Safety Risk: A Guide for Nano Companies and their Insurers

Sarahan P.C., Bushong H., Fulbright & Jaworski L.L.P., US

Nanotechnology companies are facing increasing scrutiny as federal and state agencies adopt regulations and propose recommended workplace practices and exposure standards. In addition, more studies are being released that indicate that some nanomaterials present the [...]
