Exploring the Effects of Highly Conductive Carbon Fibers on Evaporation and Desalination Rates of Salt Water

Tanzim F.S., Rahman M.M., Asmatulu R., Wichita State University, US

Water scarcity is a growing problem for large regions of the world because of the insufficient sources of fresh water to meet the demands. It is estimated that 2.8 billion people around the world have [...]

Using the Membrane Biofilm Reactor to Recover Platinum Group Metals from Wastewater

Lusk B., Zhou C., Rittmann B., Tomaswick A., Precient Technologies, US

Conventional physical and chemical processes for recovery of platinum group metals (PGM) are costly and introduce contamination into the environment. Alternatively, microorganisms can biologically recover soluble PGMs as metallic nanoparticles: e.g., convert Pd(II) to Pd(0) [...]

Effect of polymer ratio on nZVI loading onto electrospun nanofiber mat for mitigating groundwater contaminants

Ren J., Tijing L.D., Shon H.K., University of Technology Sydney, AU

Nanoscale zero-valent iron (nZVI) has been widely used for the reduction of halogenated organics and heavy metals in the groundwater. However, individual nZVI particles are mobile and prone to aggregate, thereby reducing the reaction sites [...]

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 [...]
