the main goal of this work was to synthesize and evaluate the effect of dehydration temperature on the potential application of hydroxy sodalite zeolite membrane. hydroxy sodalite zeolite membranes were synthesized via direct hydrothermal method onto a tubular alumina support without seeding in a hot air oven. the synthesized membranes were characterized by x-ray diffraction (xrd) and scanning ...

because most contaminants in water create strong interactions with hydrophobic surfaces, there are usually problems such as flux decline and pore blocking in polyethylene (pe) membranes due to irreversible adsorption of foulants on their intrinsic hydrophobic surface. therefore, in this work, attempts were made to improve the properties of pe membranes in terms of water flux and membrane foulin...

Membrane distillation (MD) is a membrane-based thermal desalination process capable of treating hypersaline brines. Standard MD systems rely on preheating the feed to drive process. However, relying carry energy limited by decline driving force as water moves across membrane, and temperature polarization. In contrast, supplying heat directly into channel, either through membrane or other channe...

Cellulose nanofibers (CNFs) with high hydrophilicity and huge specific surface area have great prospect for upgrading the performance of thin-film composite (TFC) membranes, but optimal location their incorporation in membrane is still unclear. Herein, we studied compared effects nanomaterials locations: i) embedded active separation layer (Embedded-CNFs), ii) as an interlayer between support (...

Recently, many full-sized keyboards have been designed to fold in various ways in an attempt to make them more transportable. The flexible membrane keyboard, one type of full sized keyboard, is unique because it is made from silicon rubber, thus it is fully flexible and water resistant. Although a number of flexible keyboard characteristics are the same as standard keyboards (i.e. key size, sha...

background: considering the toxic effects of heavy metals and microbial pathogens in industrial wastewaters, it is necessary to treat metal and microbial contaminated wastewater prior to disposal in the environment. the purpose of this study is to assess the removal of heavy metals pollution and microbial contamination from a mixture of municipal and industrial wastewater using membrane bioreac...
