Elaboration of new ceramic membrane from spherical fly ash for microfiltration of rigid particle suspension and oil-in-water emulsion
TL;DR: In this article, the performance of spherical fly-ash-based membrane for microfiltration of rigid particle suspension and oil-in-water emulsion was evaluated. And the results revealed that after continuously running for 10h without backwashing, high permeate flux of 2270Lm −m −2 ǫh −ǫ 1 and 159lm −lǫm −µh −« 1 were obtained in the micro-filtration process at low transmembrane pressure of 0.10

Analysis of coal fly ash properties of importance to sulfur dioxide reactivity potential
TL;DR: In this paper, fly ashes selected to provide a representative cross-section of coal classification and combustion techniques were analysed for physical and chemical characteristics that might indicate a potential for reaction with SO/sub 2/ in a flue gas desulphurization process.

Preparation of composite ceramic membrane from titania powders
TL;DR: In this paper, a titania-based composite membrane is developed, which is prepared from titania powder and stainless steel mesh by an aqueous slurry technique. But the effects of dispersion technique and heat-treatment temperature on the nature imperfections and titania agglomerates were investigated.
