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) [...]

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 [...]

Recovery of Desalination Brine Concentrate Using Waste Heat and Membrane Evaporation

Johnson D., University of Texas at San Antonio, US

The desalination processes produces highly concentrated brine effluent which is costly to dispose of for inland desalination facilities. The current study uses a membrane evaporation process to reduce brine volumes and recover treated brines. Membrane [...]

Super-porous PVDF nanofibre membranes for efficient desalination of brackish water in membrane distillation applications

Mhlanga S.D., Nthunya L.N., Khumalo N.P., Verliefde A.R., University of South Africa, ZA

Water scarcity is becoming a serious problem in Southern Africa. Recent draughts have called for exploitation of alternative sources of drinking water such as brackish and seawater. Membrane distillation is an efficient desalination process that [...]

Bromate free disinfection by high voltage pulse

Chang I-S, Hoseo University, KR

We designed and assembled high voltaged pulse generating system in our laboratory. The HVI system is consisted of power supply, high voltage generator, capacitors and impulse generator. The impulse with 10 to 20 kV/cm of [...]

Electromechanical Detection of Pathogens with Self-Assembled Nucleic Acid Biosensors

Urmann K., Bahnemann J., Chikneyan Z., Kasmaee L.M., Hoffmann M.R., California Institute of Technology, US

Infectious diseases, primarily caused by enteric pathogens, remain a major cause of death, especially in remote locations of the developing world. Routine monitoring of pathogen contaminations is therefore crucial. We seek to apply quartz crystal [...]

Integration of microfluidic chip with Loop-mediated Isothermal Amplification (LAMP) assay for rapid quantification of Enterococcus Faecalis

Han M., Kamalakshakurup G., Lee A.P., Jiang S., University of California Irvine, US

Rapid and sensitive monitoring of water quality can effectively prevent accidental human exposure to waterborne pathogens. In this project, a rapid quantification method was developed for Enterococcus faecalis, a fecal indicator bacteria (FIB), used as [...]

Development of photosensitiser functionalised electrospun nanofibre for photoremediation of of industrial waste water.

Chowdhury K.F., Millner P., Russell S., Sargeeva N., University of Leeds, UK

Increasing need of modern society and growing industrialization continuously drives the emergence of water scarcity. Water security is not only a problem for third world countries but one of the major problems within developed countries. [...]

Magna Imperio Systems: Innovating Solutions Through Technology

Page G., Magna Imperio Systems, US

Fresh, potable water is a sacred, yet scarce, resource that brings life to the world. The successful foundation of every community is reliant on the crucial interconnected relationship between water, food, and energy known as [...]

Modifications to permeable pavement structure to achieve improved heavy metal attenuation in stormwater runoff

Kuruppu U., Rahman A., Sathasivan A., Western Sydney University, AU

This paper reports a study conducted to investigate the influence of rainfall intensity and subbase materials on attenuation of heavy metals in stormwater runoff through permeable pavements. The porous structure of permeable pavements facilitates the [...]

Bio-inspired Solar Desalination with Zero Liquid Discharge

Finnerty C., Mi B., University of California-Berkeley, US

As traditional water resources become strained and demand continues to soar, desalination is being considered as a viable option to augment existing water supplies. Although advances in membrane technology have dramatically reduce the energy consumption [...]

Micro magnetic driven bidirectional turbine used in urban water mains for hydropower generation

Yang H., Du J., Shen Z., The Hong Kong Polytechnic University, HK

Data collection along water supply pipelines in an urban environment is of vital importance for urban water supply as it can provide timely detection and early warning of water leakage and other information. However, any [...]
