Performance evaluation of a locally developed domestic drinking water filter

This paper describes the design, construction and testing of a domestic water filter. Its construction was accomplished using mainly locally available materials to make it relatively affordable for both the rural and urban dwellers. The developed raw water filter was tested by using it to filter raw water samples obtained from wells, borehole and rain. The water samples were collected from different sources in Akure, Nigeria and were subjected to a series of tests before and after filtration. Comparison of results obtained with the WHO standards for drinking water showed that the filter can provide portable drinking water of the required standard. The filter average removal efficiency of turbidity, hardness, conductivity, total dissolved solid (TDS) and total suspended solid (TSS) from water samples were 95.1, 70.3, 73.1, 69.4 and 98.7%, respectively. © 2010 Taylor & Francis.
