| dc.description.abstract | About one-fifth of people on earth lack the access to safe drinking water a condition that resulted in the death of many people in developing countries. This research was aimed to prepare silver impregnated ceramic filter from clay and rice husk at different ratios (52C:48RH, 60C:40RH and 70C:30RH) where C denotes clay and RH denotes Rice Husk using three different firing temperatures (800 , 900 , 950 ) and evaluate the performance of turbidity and total hardness reduction efficiency and bacteria removal efficiency from contaminated water by determining levels of these contaminants in water before and after filtration through the filters. All filters showed capability of reducing pH and turbidity.Using 70C:30RH filters turbidity levels decreased from 23.01 NTU to less than 5NTU because of small porouristy is obtained using more clay soil and less rice husk ratios.More than 96% of the total coliform and 98% of the fecal coliform indicator bacteria are removed during filtration using filters before silver impregnation and 100% of the total coliform and 100% of the fecal coliform bacteria are removed after silver impregnation from contaminated water sources.The non-silver impregnated porous ceramic pot filters removed contaminants from environmental water samples 25.32% to 37.04% , 31.76% to 40% and silver impregnated porous ceramic pot filters 31.19% to 44.68% , 97.65% to 98.82% .Hence, the information compiled from prepared silver impregnated ceramic water filter is greatest importance for providing microbiologically improved household drinking water to prevent and control waterborne bacterial diseases and reduce heavy metal contaminant from contaminated water. | en_US |
