Improving Water Management in Fuel Cell Flow Channels via Oscillation of Water Droplets
To achieve maximum efficiency and reliability in a PEM fuel cell, a balance between keeping the membrane from becoming too dry or too wet must be monitored carefully. At present, product water is moved through [...]
Off-Grid Fuel Cell System for High Power Quality Applications
Lima R.J.S., de Almeida A.T., Mendes A.M.S., Mendes A.M.S., Cardoso A.J.M., University of Coimbra, PT
There is a variety of critical loads, such as information technology, telecommunication, medical equipment and industrial process controls, which require high power quality. Conventional approaches to provide high power quality levels include battery based uninterruptible [...]
Drinking water treatment with Caspian region natural sorbents
The present work is focused on developing effective and efficient mass consumer household filters to treat drinking water with natural sorbents which is especially important for developing regions communities. The aim of the research was [...]
Unrestricted Water Reuse & Low Energy Cluster Wastewater System Producing TN < 4 mg/l – Malibu Creek Plaza, Malibu, CA
The Malibu Creek Plaza is a shopping plaza consisting of both retail and commercial businesses, located in an environmentally sensitive area adjacent to the famous Surfrider Beach in Malibu, California. In 1999 the California Regional [...]
Water Purification Using Carbon Nanotubes
As we learn more about the hundreds of contaminants common in water, the decline of our water infrastructure, and the potentially harmful effects of chemical treatments, it is not surprising that consumers are turning to [...]
Direct hydrothermal synthesis of LiMn2O4 spinel and lithium ion selective adsorption
Spinel LiMn2O4, in which the [Mn2O4] framework provides a three-dimensional interstitial space for Li+ transportation, shows excellent Li+ insertion and extrusion property from the Mn-O lattice. The lithium ion-sieve effect strongly depends on the crystal [...]
Wastewater Effluent Total Nitrogen of 3 mg/l with Cost Effective, Low Maintenance Cluster Treatment System
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 [...]
Baltimore Charter on Sustainable Water Systems
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 [...]
Instantaneous Microbial Detection Demonstrated for Air & Water
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 [...]
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 [...]
Multi-Functional Carbon Nanotube Based Filtration Material
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 [...]
