Photocatalytic membranes exhibit great potential for water treatment since they combine the filtration and photo degradation in a single unit. Although blending photocatalytic nanoparticles into polymeric thin film remains the simplest method to prepare the photocatalytic membrane, the entrapped photocatalyst showed less catalytic activity due to the agglomeration and shielding effects in the p...
Background & Aims: Water microbial quality in hemodyalsis centers is particularly important in medicine. The aim of this study was to investigate cultivable bacteria present in outlet of water treatment systems in hemodialysis centers affiliated to Tabriz University of Medical Sciences. Materials & Methods:This cross-sectional descriptive study was performed in three hemodialysis wards a...
eclaimed municipal wastewater is becoming a source of public water supplies in places where water is limited. In countries such as Japan, South Africa, and France, legislation encouraging innovative technologies that render wastewater fit for reuse has stimulated the development of alternative processes.1 The use of membranes in tertiary treatment and advanced purification evolved as a promisin...
Technical and scientific developments have facilitated an increase in human life expectancy quality, which is reflected a large growth of global population [...]
Zirconia ultrafiltration membranes are widely developed and used for past several years. But the conventional sol-gel methods of zirconia membrane preparation involve many steps. In the present study an attempt was made to develop defect free zirconia ultrafiltration (UF) membrane in single step coating of zirconia nanopowder suspension by slip casting method over multichannel ceramic support. ...
membrane technology is used to separate water or solvents from salts or pollutants. this technique could be used for water treatment. for using of polyether sulfone (pes) hollow fiber membranes in water treatment processes, the pes hollow fiber membranes were prepared by dry-wet spinning method and heated in an oven at: 120°c, 150°c and 180°c. the effect of heating on performance of membranes w...
