Design of ceramic filters using Clay/Sawdust composites ...
When the filters are not soaked, it is observed that the out-flow of the filters without sawdust is lower; and that the passage of water through the filters reinforced by the sawdust is raised more, precisely for filter CM3-5 (900 °C) than for CM4-5 (1000 °C) during the first 30 min. However, the tendency reverses itself from the 40th minute.
