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 [...]

Behaviour of mesoporous silica (MCM-41) supported catalysts in degradation reactions

Guthrie C.P., Reardon E.J., University of Waterloo, CA

Research was carried out to investigate several aspects of Mobil’s composition of matter #41 (MCM-41) pertaining to its potential application in water treatment technologies. It was found that Pd-impregnated MCM-41 (Pd/MCM-41) has enhanced stability in [...]

Synthesis and Study of Novel Nanostructured Membranes Incorporating N-doped CNTs for Water Treatment

Mhlanga S.D., Phao N., Nxumalo E.N., Mamba B.B., University of Johannesburg, ZA

The presentation presents blend membranes of polyethersulfone containing Ag nanoparticles dispersed on N-doped carbon nanotubes (N-CNTs). The blend membranes were checked for any improved properties and tested for their efficacy in removing model pollutants from [...]

Industrial symbiosis and green chemistry: one’s waste is another’s resource!

Hunt A.J., Dodson J.R., Parker H.L., Budarin V.L., Matharu A.S., Clark J.H., Green Chemistry Centre of Excellence, UK

Industrial symbiosis, the sharing of industrial by-products to add value, reduce costs and improve the environment, will become increasingly important for the sustainable future of our planet. By employing this philosophy alongside green chemical technologies [...]

Increasing the Efficiency of Photocatalytic Water Treatment with Titanium Dioxide Nanoparticles by Control of Crystal Shape

Rickerby D., European Commission Joint Research Centre, IT

The most commonly employed photocatalytic material is titanium dioxide; anatase is the photocatalytically reactive phase. Highly dispersed anatase nanoparticles have a large specific surface area. However the reaction is inherently inefficient because only a very [...]

Microwave assisted synthesis of CaO nanoparticles and use in waste water treatment

Roy A., Bhattacharya J., Indian Institute of Technology, Kharagpur, IN

Clean water (i.e., water that is free of toxic chemicals and pathogens) is essential to human health. Advances in nanoscale science and engineering are providing unprecedented opportunities to develop more cost effective and environmentally acceptable [...]
