Synthesis of Low Cost Ceramic Membranes for Reduction of Water TDS

Ceramic membranes are used in water treatment process have many advantages in comparison with usual polymeric membranes. Hence in this study synthesis of low-cost ceramic membranes with simple and accessible materials also properties of water passing through it were discussed. An apparatus was made for testing membranes. Then porous ceramic membranes were made through press and slip casting process. Row materials which are contain ceramic powder such as: Alumina with 84% wt, Kaolen with 12%wt and Feldspar with 4%wt and some additives, various tablet of ceramic membranes in several thickness was made in different conditions of pressure, temperature and materials amount. Generally, results show the power of ceramic membranes in water treatment process, usage a tablet with 20mm thickness could decrease TDS from 950 ppm to 400 ppm and in usage a series of tablets in 10, 10 and 20mm TDS decreased from 1200 ppm to 320 ppm.
