Abstract:
We have attempted an experimental study on the effects of introducing grog in different proportions to the composition of ceramic water filters (CWF). The different compositions of clay, sawdust mixed with grogs were compacted to cylindrical discs at high pressures and then fired to 850 oC. The effectiveness of the filters was measured based on the rate of water percolation through the filters, turbidity of the filtrate and e-coli removal efficiency of filters. The introduction of grogs was found to improve the filtration rates of filters, although if so much proportion of it is added the quality of filtrate is lowered.
