Abstract-Water borne infections are the number killer of children under five years in developing countries. The main reason is the consumption of untreated drinking water. Here we report on the use of ceramic water filters in reducing Escherichia coli, a surrogate for pathogens in drinking water and can be applied in a rural household. For microbiological analysis, the two ceramic water filters, one from Mukondeni and the other one from Sese in Zimbabwe reduced the high microbial load of the raw water. The result showed that the counts as colony form units, of coliform in the purified water was zero and in raw water was too many to count; these colonies were probably removed by the ceramic water filter. The microbial counts in the purified water were zero colony forming units per 100 ml and within the SANS 241 guidelines values. The ceramic water filters from Mukondeni and Sese were able to improve the microbial quality of the raw water. The Sese ceramic water filter was slow and thus further improvements are required in the composition of materials by increasing the saw dust component and reducing the clay component. Thus, ceramic water filters are suitable for use at household level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
