ABSTRACT

The aim of this work is to design a portable tubular filter pipe for borehole water purification system. The materials used in the portable tubular filter pipe (sand layer depth of 0.15m of size 0.8 – 2mm and coarse gravel layer of 0.02m of size 5-8mm) were sourced locally. The coarse aggregate (gravel) layer served as support and distribution of water while the sand layer served as the filter medium. The diameter of the portable tubular filter pipe was assumed to take 4 inches PVC diameter pipe (0.1016m). The design reveals that the filter area is 0.0479m², the flowrate in the filter is 8 X 10^-5m³/s, the filter volume is 0.02m³ and the headloss in the filter is 0.5m. Tests were carried out on borehole water and system filtered water. The results show that the portable tubular filter pipe performed relatively well in purifying borehole water. The model constructed for the tests was a prototype.
