摘要


There is an urgent need to identify cheaper and efficient methods of removing contaminants as the demand for clean water rises. In this study, the household water filters were prepared from low-cost materials based on kaolin powder and combustible materials as palm fronds powder which acts as pore creating agent. The filter samples with different content (0, 10, 20, 30) wt% of palm fronds powder were fabricated using a dry pressing method and fired at 1250 °C. Thereafter, the porous ceramic filter samples were carbonized at 950 °C for 6 hrs. The ceramic filters were characterized by X-ray diffraction and SEM. Physical properties (linear shrinkage (L.Sh.), apparent porosity (A.P.), water absorption (W. A.), apparent solid density (A.S.D.), permeability and diametrical compression strength) before and after carbonization was also studied. The total dissolved solids (TDS), turbidity (Tur.), pH, conductivity (Ec), free Cl, and salt percentage (sal %) of water from both household water filters with and without activated carbon was also examined before and after filtration. The presence of heavy metals from the water was analyzed before and after filtration.
