Electroflox® Pilot plant for primary wastewater treatment of leachate

Marriaga-Cabrales N., Machuca-Martinez F., Donneys-Victoria D., Alvarez-Pugliese C.E., UNIVERSIDAD DEL VALLE, CO

Landfill leachates are liquid effluents that contain a high pollutant load and represent a serious environmental challenge for the disposal sites; Even after the useful life of a landfill, leachates continue to be generated for [...]

Resilient water treatment technologies and challenges for the removal of emerging contaminants – Perfluorinated compounds

Singh R., Singh T.S., Singh R., Singh T.S., University of Virginia, US

Due to their global presence, persistence, and adverse health effects, perflurinated compounds (perfluoroalkyl and polyfluoroalkyl substances PFASs) have become major chemical of concern for drinking water supplies worldwide. Presence of these PFCs in various geographical [...]

Ionic Diodes in Water Desalination & Purification

Marken F., Madrid E., Aaronson B.D.B., McKeown N.B., University of Bath, UK

Ionic rectifiers (or ionic diodes) work like electronic diodes, but allow ion flow to be controlled. We have developed novel ionic diode devices based on ionomer and polymer materials coated onto microholes to typically 5 [...]

Development of alumina/iron oxide nanocomposites as adsorbents for arsenic and fluoride removal from aqueous solutions: Process Optimization

Prathna T.C., Kumar Sharma S., Kennedy M., UNESCO-IHE, NL

The study was designed to optimize the process for the synthesis of alumina/ iron oxide nanocomposites and to investigate their potential as a sorbent to remove fluoride and arsenic from contaminated water. The nanocomposites had [...]

Greenhouse Gas Emissions Reductions Research and Development Leading to Cost-Competitive Coal-to-Liquids (CTL) Based Jet Fuel Production

Archer D., U.S. DOE, US

Significant opportunities to reduce GHG emissions of CTL fuels fall under three categories: increasing efficiencies of conversion technologies; supplementing coal with feedstocks and energy inputs that have lower lifecycle GHG emissions; and carbon capture, utilization, [...]

Synthesis and properties of a series of bio-based surfactants with different hydrophobic chain length

Sato S., Habe H., National Institute of Advanced Industrial Science and Technology (AIST), JP

Glyceric acid (2,3-dihydroxypropanoic acid, GA) is a natural organic compound found in specific plants as a minor constituent, but can be mass-produced biotechnologically from glycerol, a by-product of biodiesel fuel production. We synthesized a series [...]

Steam Explosion and Fermentation of Sugar Beets from Southern Florida and Minnesota

Dorado C., Cameron R.G., Cooper K., United States Department of Agriculture, Agricultural Research Service, US

Sugar beets have been grown primarily in the Midwest for the production of table sugar and have recently gained interest for planting and harvesting in other areas of the U.S. for use as cattle feed, [...]

Are microalgae a possible energy source for a sustainable world?

Kava V., Vargas J.V.C., Mariano A.B., Ordonez J.C., Federal University of Parana, BR

In recent years, much scientific research has been directed to the search for viable alternatives to clean energy. Investments in research and development of renewable energy sources have been implemented, and the economic viability of [...]

Investigating the Effects of Media and Light Sources on the Growth of Botryococcus Braunii

Sengul A.B., Rahman M.M., Asmatulu E., Wichita State University, US

The reduction of world’s petroleum reserves and the environmental problems created by emissions have increased the interests in alternative energy. Biodiesel is an environmentally friendly and biodegradable alternative fuel that is obtained from renewable sources. [...]

Improving Hybrid Efficiency and Flexibility by Integrating Thermal Energy Storage into the Fuel Cell System

Tucker D., Harun N.F., Zaccaria V., Shadle L., National Energy Technology Laboratory, US

Power plants must be flexible in operation to meet changing load requirements throughout the day while ensuring economic feasibility. As renewable energy systems penetrate the market producing inconsistent power, the primary concern of power plants [...]
