Dye has been widely used in textile industry but the discharge of textile wastewater
to the river give serious impact towards environment. This study was conducted to
produce high performance yet low cost natural ceramic membrane for treating dye
effluent. The ceramic membranes were prepared from clay and different proportions
of sawdust by slip casting method before sintering at 1000 o C for 2 hours. The
performances were characterized in terms of porosity, density, mechanical strength
and permeability. Results showed that the increase in sawdust proportion increased
the porosity and permeability and also decreased the density and mechanical strength.
Combination of clay with 20% sawdust showed the best performance. However, these
low cost ceramic membranes have relatively large pore size and therefore are
considered less effective for dye treatment application.
