Membrane technology is important in industrial wastewater and water treatment. Recently, the polymeric membrane widely chosen these applications. However, they are lowtemperature ranges, low corrosion resistance, lifespan. Thus, researchers actively trying to develop a better such as natural clay ceramic due their excellent chemical, mechanical thermal high-pressure application long This detail...

2016 © American Water Works Association JOURNAL AWWA OCTOBER 2016 | 108:10 Microfiltration (MF) membranes are low-pressure membranes that generally have pore sizes in the range of 1 to 0.1 μm. They can effectively reject bacteria, protozoa, and colloidal particles by size exclusion. The physical rejection of viruses and the dissolved fraction of natural organic matter (NOM) by MF (0.1 μm nomina...

• Research, develop and demonstrate the Ion Transport Membrane (ITM) Syngas ceramic membrane reactor system for the low-cost conversion of natural gas to hydrogen and synthesis gas. • Scale-up the ITM Syngas reactor technology through three levels of pilot-scale testing and precommercial demonstration. • Obtain the technical, engineering, operating and economic data necessary for the final step...

14 The objective of this study was to develop a new measurement technique for the determination of pore size distributions (PSDs) of polymeric and ceramic membranes, including NF, UF, and MF membranes. The proposed method uses the fractional rejection (FR) concept of a solute in membrane pores. Experimental measurements were conducted using a high performance liquid chromatography (HPLC) equipp...

Abstract: Nano pore Mordenite membranes were prepared on the outer surface of ceramic tubular tubes via hydrothermal synthesis and evaluated for dehydration pervaporation of water unsymmetrical dimethylhydrazine UDMH mixtures. Highly water-selective mordenite membranes were prepared and the optimum reaction condition was found to be 24 h crystallization time and 170 °C crystallization temperatu...

In this investigation, two methods for characterizing membrane surface potential are investigated. Results from atomic force microscopy (AFM) analyses are compared with streaming potential measurements. In calculating surface potential from AFM force measurements, assumptions of constant charge and constant potential were both considered for modeling electrostatic interactions. For a ceramic mi...

A multilayer composite ceramic membrane was prepared by depositing a nano-scale layer of SiO2 on top of a modified porous alumina support by chemical vapor deposition (CVD) method. The modification of the support was carried out by adding a graded layer of Al2O3 (γ-alumina phase), using sol-gel method. An optimized temperature of 700 K for intermediate layer calcination was gained by XRD analys...
