APPLICATION OF CERAMIC FILTER FOR IMPROVING SURFACE WATER QUALITY (Pages : 68 - 73)

Ceramic filter was used to remove pathogenic bacteria and other impurities from contaminated water. Three types of ceramic filters were prepared with locally available soil and rice husk and operated for 5 days. The combinations of rice husk and clay particles were used to prepare ceramic filter core, which was burnet in potter kiln and fixed in clay pot. A total of 30 water samples were collected from inlet and outlet of filter and their flow rate was measured. The collected water samples were analyzed for turbidity (Nephelometric Turbidity Unit; NTU), total coliform (TC) and fecal coliform (FC). The filtration rate of ceramic filter was increased with increasing rice husk percentage and highest filtration rate was 702.64 ml/h in ceramic filter made up of 20% rice husk, while for 10% rice husk the value was 191.2 ml/h. The highest turbidity removal efficiency, 56%, was found in 10% rice husk mix ceramic filter but its performance reduce when rice husk percentage increase in ceramic filter core. For 15% rice husk mix filter ceramic the value was 40% and for 20% the value was 24%. In case of ceramic filter made up of 10% rice husk, the TC removal was 80% but FC removal was 90%. We found that the performance of ceramic filter reduced with increasing rice husk percentage. It was concluded that ceramic filters were able to remove turbidity and pathogenic bacteria from contaminated water which meet the drinking water demand of low income group of hard to reach saline prone coastal zone of Bangladesh.Download
