Abstract | Manganese ore (pyrolusite) and iron ore (haematite), both raw and chemically treated with ferric hydroxide, alum, lime, or manganese dioxide, were subjected to batch sorption and downflow column tests to assess their capacity to remove Escherichia coli and clay turbidity from water. Lime or alum treated manganese ore appeared to be a promising medium for use in low-cost household water filters. In filtration of a polluted canal water heterotrophic bacteria concentrations were reduced from 400-1000 CFU/mL to 1-4 CFU/mL, E.coli from 100-400 CFU/mL to zero CFU/mL, and turbidity from 30-40 NTU to 2.5 NTU. |
