Membranes

This work deals with thin film composite membranes prepared from m-phenylenediamine and 1,3,5benzenetricarbonyl chloride by interfacial polymerization on the surface of a polysulfone substrate, and graphene oxide was embedded into the membrane during membrane formation to improve the membrane perform

Access to clean water resource continues to be the most urgent and pressing global issue where hiking economic and ecological needs have urged for more water-efficient technologies. Membrane-based separations for desalination are playing an increasingly important role to provide adequate water resour

Microbiological contamination of polymeric membranes in the process of their exploitation is an essential problem of membrane technology. It results in the increase of manufacturing costs, destruction of membranes, operating life reduction and secondary contamination of water by the metabolism produ

In the last two years, international AQUAPOT project has carried out the installation of three drinking water treatment plants based on ultrafiltration (UF), in rural areas of the Andean region of Ecuador without access to drinking water. In addition, the project has carried out an applied parallel

The Intermunicipal Water Company of the Veurne region (IWVA) reuses wastewater effluent for groundwater recharge of an unconfined dune aquifer since July 2002. The ‘Torreele’ reuse plant has a production capacity of 2,500,000 m3/y. Due to the sensitive environmental nature of the dune area, the qual

Since stainless steel must be rinsed with water after pickling operation with mixtures of nitric and hydrofluoric acids, the present investigation was undertaken to define a major step towards the close loop circulation of water in steel plant. This can be done by a new procedure for removing also n

Development of systems with reduced emission of pollutants is one of the major challenges of this century. Fuel cells promise to provide clean and renewable source of energy, which can operate on many fuels. They are promising candidates for transportation and portable power source applications. The

Sustainability has various meanings in the context of water reclamation and reuse. In one sense it acknowledges that to sustain our water supplies we must develop technologies that can efficiently reclaim wastewater to augment natural supplies. Membrane technology is playing a vital role in this app

Membranes are very effective in removing a wide variety of water contaminants. Therefore, the use of these processes in water purification to replace or to improve conventional treatment has increased. An inherent problem of membranes is fouling, the accumulation of materials (foulants) near, on, or

Ultrathin alumina hollow fibers were prepared by a phase inversion and a sintering method. A polysulfone solution containing well-dispersed alumina powders is spun, which is then sintered at elevated temperature. To increase the packing density of alumina powers in the hollow fiber, 1,4-dioxane was
