A new kind of environmental ceramics medium which was made of industrial solid wastes discharged by Shandong Alum Corporation has been used in the process of drinking water treatment. New techniques were introduced to ensure its remarkable advantages such as high porosity and strength. The results of practical application show that this sort of filter medium has shorter filtration run, shorter mature period and higher filter deposit capability compared with traditional sand filter medium. Moreover, up to 25%- 30% of the daily running costs are expected to be reduced by using this ceramics medium.
