Effect of Grogs on in the Performance of Ceramic Water Filters

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...

Water Purification by Double Filtration Using Ceramic Filters

This paper presents the results of an experimental study on the effects of double filtration on the rate of water percolation and E. coli removal efficiency of ceramic water filters made from mixtures of different ratios of clay powder, fine sawdust and powder of grog. The results show that double filtration produces superior quality of filtered water compared to single filtration although the rate of water percolation is higher for...
