Removal of Zn(II) from Aqueous Solution by Biosorption using two Green Algal Species Oscillatoria sp. & Spirogyra sp.

Singh D., National Institute of Technology, Kurukshetra, IN

Pollution due to heavy metals has become an environmental problem of worldwide concern due to their increased discharge, toxicity, non-biodegradable and persistence nature. Major anthropogenic sources of heavy metals include metal extraction, metal fabrication, metal [...]

Enhancing Combustion and Heat Exchange Through Electrical Augmentation

Goodson D., Rutkowski R., Osler G., ClearSign Combustion Corporation, US

We have observed that software-controlled propagation of insignificant amounts of electrical energy through a flame region enhances both combustion efficiency and the transfer of thermal energy in an electrically conductive burner and heat exchange system. [...]

Valorization of Waste in a Gasification Plant to Clean Power Production

Pérez-Fortes M., Bojarski A., Ferrer-Nadal S., Kopanos G., Nougués J.M., Velo E., Puigjaner L., Technical University of Catalonia (UPC), ES

This work presents a structured and validated conceptual model of an integrated gasification combined cycle (IGCC) power plant. A pressurized entrained flow (PRENFLO) gasifier, subsequent gas cleaning operations, a heat recovery steam generator (HRSG) and [...]

By-product Synergy Networks, Driving Innovation through Waste Reduction and Carbon Mitigation

Mangan A., Olivetti E., US Business Council on Sustainable Development, US

By-product synergy (BPS) is the matching of under-valued waste or by-product streams from one facility with potential users at another facility to create new revenues or savings with potential social and environmental benefits. This presentation [...]

Conversion of Glycerol-rich Product (GRP) into Biopolymers

Freitas F., Pais J., Alves V.D., Carvalheira M., Costa N., Oliveira R., Reis M.A.M., Universidade Nova de Lisboa, PT

Glycerol, a byproduct of many industrial processes, mainly in biodiesel production, is generated in quantities far beyond current consumption in traditional applications, thus making it a residue for which interesting applications are lacking. The objective [...]

Multi-Functional Carbon Nanotube Based Filtration Material

Cummings A., Seldon Technologies, Inc., US

The very small diameters of carbon nanotubes (CNTs) present relatively low resistance to fluid flow. This, combined with their high surface area, means that highly-efficient, bio-contaminant removals are possible with a thin filtration media possessing [...]

Computational Modeling of Ligands for Water Purification Nanocoatings

Vanka K., Houndonougbo Y., Lien N.R., Harris J.M., Farmen L.M., Johnson D.W., Laird B.B., Thompson W.H., University of Kansas, US

Electronic structure and molecular dynamics calculations are being used to investigate ligand-based nanocoatings for use in drinking water purification applications. The aim is to use computational chemistry to aid in the development of design principles [...]

Instantaneous Microbial Detection Demonstrated for Air & Water

Jiang J.P., McGill S., Morris S., BioVigilant Systems, Inc., US

Traditionally, growth based techniques have been the standard in environmental monitoring for evaluating the quality and quantity of microbial content. However, many studies have underscored the inadequacy of these techniques: (1) to provide environmental microbial [...]

Baltimore Charter on Sustainable Water Systems

Nelson V.I., Coalition for Alternative Wastewater Treatment, US

The Baltimore Charter on Sustainable Water Systems was drafted as a commitment to design new water systems that mimic and work with nature. These systems will both protect public health and safety and will restore [...]

Wastewater Effluent Total Nitrogen of 3 mg/l with Cost Effective, Low Maintenance Cluster Treatment System

Lombardo P., Lombardo Associates, Inc., US

Excessive nitrogen levels pose a threat to the ecological health of water resources in the United States due to excessive algal growth that causes ecological decline. The NitrexTM denitrification filter is a low cost, low [...]
