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 [...]

Achieving a Sustainable Metals Market for the Manufacturing Industry

Warren T., Rechargeable Battery Recycling Corporation, US

Metals are a key resource in today’s manufacturing processes. However, the environmental costs of procuring and processing new metals can potentially set companies back in their endeavors to be more environmentally friendly, while also increasing [...]

Method for Converting Waste Plastic to Hydrocarbon Fuel Materials

Sarker M., Natural State Research, Inc., US

The increased demand and high price for energy sources are driving efforts to convert organic compounds into useful hydrocarbon fuels. Although much of this work has focused on biomass, there are strong benefits to deriving [...]

Enhanced Biodegradation of 2,3,4,5,6-pentachlorocyclohexan-1-ol — a b-HCH Metabolite — in the Presence of a and g-HCH Isomers by Pseudomonas aeruginosa ITRC-5

Singh A., Kumar A., Misra K., Rice University, US

Chlorinated insecticide hexachlorocyclohexane (HCH), which is still used in many countries in agriculture and forestry, leads to environmental problems. HCH consists of a mixture of four isomers: a-, b-, g-, and d. Efforts have been [...]

Isolation and Characterization of Benzene Degrading Bacteria from Gasoline Contaminated Water

Singh A., Sar P., Bennett G., Rice University, US

The BTEX (benzene, toluene, ethylbenzene, and xylene)compounds are hydrocarbon pollutants that are considered as significant threat to the health and environment. Among BTEX, benzene is of major concern, because it is soluble, mobile, toxic, carcinogenic [...]

The Need and the Quest for Developing Water Treatment Systems for Masses Which are Low Cost, Low Tech and Use Locally or Easily Available Material

Shukla S.S., Anastas P., Bhanumati S., Mussadaq M., Lamar University, US

In todays world, a large set of environmental challenges exist. The extent of the environmental damage is alarming and the consequences could be dire. Existence of healthy life requires availability of safe food and clean [...]

12 Billion Dollars Annually Expended on Throw away Filters- There is a new technology alternative to this wasteful practice

Bromley D., Enprotec, CA

In a world that is focussed at finding methods to use less energy or alternatives to existing energy driven products, one obvious change that is essential is the reduced use of disposable products. Specifically this [...]

Effect of surfactant on TiO2/UV mediated heterogeneous photocatalytic degradation of DDT in contaminated water

Sinha S., Tapia-Orozco N.G., Acosta-Ramírez D.S., Rodríguez-Vázquez R., CINVESTAV, MX

The toxic effects from the use of pesticides are of great concern to the environment. The pesticides containers are not treated according to the Mexican normativity and hence increase the pollutant levels in the environment, [...]

A Sonoelectrochemical Synthesis of Nanosized CdS on TiO2 Nanotube-Array for Enhancing Photoelectrochemical Reactivity

Wang C-L, Sun L., Yun H., Li J., Lin C.J., Lai Y.K., Lin C.J., Xiamen University, CN

The nanoparticles of CdS were precipitated onto a self-organized TiO2 nanotube array photo-electrodes by using sonochemical synthesis combining with constant current electrochemical deposition. It is indicated that the CdS nanoparticles with average diameter of 28.1 [...]
