Development and Performance Evaluation of a Ceramic Filter for Point-of-Use Water Purification

Abstract

In this work, a ceramic filter for point-of-use water purification was designed, fabricated and tested to evaluate its performance in filtering water to the World Health Organisation (WHO) standards. The results of pH of water samples obtained after filtration ranged from 7.68 to 8.11. The range of values obtained after filtration for turbidity, hardness, conductivity, total dissolved solid (TDS) and total suspended solid (TSS) from water samples were 0.07 to 0.55 NTU, 6.0 to 34 mg/L, (1.5 to 3.3) x 10-3S/m, 4 to 25 mg/L and 0.04 to 0.11 mg/L, respectively, while the filter average removal efficiencies of these parameters were 93.1, 85.1, 91.6, 92.3 and 91.4%, respectively. Comparison of the results with the WHO standards for drinking water showed that the ceramic water filter can provide potable drinking water of required standards.
