Description:
Water samples were taken from three different shallow wells in Abeokuta, Ogun state Nigeria (West Africa). These wells are represented by as raw water A, B and C and were filtered using sand as filter media, sand grains of different sizes was used. The raw water was filtered with fine sand (column 1), coarse sand (Column 2) and very coarse sand (column 3), these loadings are homogenous and the fourth column contains there three sand layers. The filtered water was subjected to laboratory analysis which includes the following: pH value, TDS (Total dissolved solids), EC (Electrical conductivity), TS (Total Suspended Solid), Calcium, Magnesium, Potassium, Hardness and Sodium. The obtained laboratory test results were compared with W.H.O standard for highest desirable and maximum permissible. One way ANOVA and bar Chart are the statistical tools employed in analyzing the data. The fine sand homogenous filter gives the best output, and then followed by the coarse sand, and then the mixture of the sand also gives preferable outputs. The homogenous fine sand media flow rate was slower but give the best output. In situation where sand particles is very small, bed depth is very high, minimal or no chemical treatment will be required after filtration.
