ABSTRACT During the last 35 years membranes have evolved from a laboratory tool to industrial products with a wide variety of applications including desalination of sea and brackish water and treatment of industrial effluents Today a large number of research works is done on ceramic membranes due to their inherent stability at hard operating conditions in comparison with polymeric membranes In this research work an asymmetric ceramic membrane was manufactured by slip casting method using reactive alumina The experiments were designed by Taguchi method and the quantitative effect of important parameters such as sintering temperature solid loading and binder content on porosity and mean pore size of the membrane were investigated In addition the optimum level of dispersant in each solid loading was GHWHUPLQHG DQG WKH HIIHFW RI GLIIHUHQW EDOO PLOOLQJ WLPHV RQ VLQWHUHG ERG V SURSHUWLHV ZDV probed The cut off diameter of alumina powder was 4 012 m and Tiron was added to the suspension as a dispersant Also PVA solution was used to prevent cracking during drying process According to the obtained results ball milling had important effect on the slip cast ERG V SURSHUWLHV DQG WKH EHVW PLOOLQJ WLPH ZDs found 3 hours Taguchi analysis showed that sintering temperature is the main effective parameter on membrane porosity and this decreased largely with temperature increasing The effects of sintering temperature and PVA content on membrane mean pore size were almost in the same order of magnitude and twice of this effect for solid loading Very small contribution of error on the defined response proved that experiments were carried out in controlled condition pdfMachine is a pdf writer that produces quality PDF files with ease Get yours now Thank you very much I can use Acrobat Distiller or the Acrobat PDFWriter but I consider your product a lot easier to use and much preferable to Adobe s A Sarras USA
