Development of a New Experimental Tool To Identify CO2 Absorption Parameters in Aqueous Amine Solutions

Wylock C., Dehaeck S., Boulay E., Colinet P., Haut B., Université Libre de Bruxelles, BE

The gas-liquid carbon dioxide (CO2) absorption by aqueous solutions of amine mixture is one of the up-to-date CO2 capture technology. This work is realized in collaboration with Cansolv Technologies Inc., which is a design office [...]

Heterogeneous Photo-Fenton Oxidation on Nanosized Pt/Perovskites as Clean and Efficient Process for Organic Pollutants Removal from Wastewater

Sannino D., Isupova L.A., Ciambelli P., University of Salerno, IT

Heterogeneous photo-Fenton oxidation of organic compounds is an advanced oxidation process in wastewater treatment allowing to overcome the main drawbacks of homogeneous photo-Fenton process. In this work we compare the performances of honeycomb monolith structured [...]

membrane technology in fishery industry: An state of art in nanotechnology

Sriniwas B.D., Sharma R., RTM University of Nagpur, IN

A large amount of raw nanomaterials is processed with the increasing demand of fishery products. Membrane technology and bioprocessing have been increasingly involved in fishery industry, particularly for the treatment of fishery wastes. Fishery nanowastes [...]

Agriculture Industry Sees Green in Wireless Technologies

Ersavas B., Comucicnao, Inc, US

While green is certainly considered good, applying advanced wireless technologies across the agriculture industry’s food chain is great. Bringing mature machine-to-machine (M2M) wireless communications to this broad industry – which includes growers, greenhouses, transporters and [...]

Precipitation, Adsorption and Inhibitory Effects of Nano Copper in Wastewater Activated Sludge

Smeraldi J., Rajagopalan G., Cooper W.J., Hosseini T., Rosso D., University of California Irvine, US

Objective of this study is to compare the fate, removal and inhibitory effects of nanocopper (oxide) with ionic copper in activated sludge. Impacts of functionalization (complexation) of nanocopper as well as the mechanism of nanocopper [...]

Design of a POSS-modified Zeolite Structure and the Study of the Enhancement of Ammonia-nitrogen Removal from Drinking Water

Lin D., Wang D., Zhang Q., You H., Shetty K., Hu L., Harbin Institute of Technology, CN

This research explored the utilization of a waste resource, rice hull ash (RHA), for the synthesis of the polyhedral ologomeric silsesquioxane (POSS) modifier for mesoporous zeolite molecular sieve (ZMS) to enhance NH4+ ion-exchange capacity in [...]

Studies on the kinetic properties of photocatalytic degradation of phenol in water using ZnO nanopowder as a photocatalyst

Tao Y., Cheng Z.L., Ting K.E., Yin X.J., Singapore Polytechnic, SG

In recent years, advanced oxidation processes (AOPs) have been proved to be one of the most effective methods to remove organic pollutants from water and wastewater. These processes are based on the generation of the [...]

Using Zeta Potential to Optimize the Water Clarification Process in a Full-Scale Water Production Facility

Nobbmann U., Gertig K.R., Billica J.A., Morfesis A., Malvern Instruments, Inc., US

Zeta potential provides a measurable value to monitor optimal water clarification capabilities. The magnitude of the zeta potential value indicates the repulsive interaction between particles; a zero zeta potential means that the conditions for the [...]

Ion Rejection Properties of Nanofiltration Membranes With Inhomogeneous Charge Distribution

Szymczyk A., Zhu H., Balannec B., University of Rennes 1, FR

Ion rejection properties of NF membranes with inhomogeneous fixed charge distributions are investigated theoretically. It is shown that the occurrence of spatial inhomogeneities in the fixed charge concentration may lead to an enhancement of the [...]

Analysis of Membrane Filtration Efficiency in Removal of Metal Oxide Nanoparticles from Aqueous Nanoparticle Suspension in the Presence of Coagulation Pretreatment

Surawanvijit S., Kim M., Cohen Y., University of California, Los Angeles, US

The introduction of nanoparticles (NPs) into aqueous environment is expected to rise with increased manufacturing and use of nanoparticles. There is a need to identify efficient and methods for NP removal and such methods must [...]
