Energy Generation from Carbonaceous and Nitrogenous Pollutants via Ammonium, Methane, and Carbon Dioxide Reformation

Lee P-H, Ni M., Xu L., Dong F., The Hong Kong Polytechnic University, HK

An unprecedented integrated electrodeionization–solid oxide fuel cell (EDI–SOFC) system is developed for energy capture from carbonaceous and nitrogenous pollutants from wastewater. The feature of this system is that both carbonaceous and nitrogenous pollutants can be [...]

Metals disinfection of E. coli in synthetic groundwater and effects of varying water chemistry

Edokpayi J.N., Singh R., Odiyo J.O., Smith J.A., University of Venda, ZA

The sustainable access to clean and safe drinking water remains as global challenge as large numbers of people still consume water that is not safe. Diarrhea; a preventable waterborne disease remains the major cause of [...]

Application of a Novel Cold Atmospheric Plasma for Water Decontamination

Kim H., Izadjoo M., Izadjoo S., Truong H., Izadjoo M., Izadjoo S., Trideum Biosciences and ChiScan LLC, US

In recent years, non-thermal atmospheric plasma has been considered as potential decontamination technology. The plasma can interact with ambient atmosphere and generate a variety of reactive species such as ozone, hydrogen peroxide, radical, atomic and [...]

Electrocapacitive Desalination of Brackish Water Using Biochars

Vander Wal R., Sengupta A., Rajagopalan R., Penn State University, US

The principle of capacitive deionization (CDI) has been known for some time, as a spin-off of electrochemical capacitance. Instead of storing energy, the purpose of CDI is to store (temporarily) salt, extracted from the water. [...]

Enhancement of Heat Transfer Coefficient Using Fe2O3 –Water Nanofluids

Zoulia N.I., Mohammed S.A.M., Al-Dahhan M.H., Missouri University of Science and Technology, US

Research efforts have been made to increase the heat transfer rate, energy, and efficiency. Some of these efforts include the application of fins, compact heat exchangers, microchannel, and many others. Recently, nanofluids have been introduced [...]

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, [...]
