| dc.description.abstract | The study of "Design and Testing of Sand and Gravel Filter for Artificial Groundwater Recharge" was carried out at the Instructional Farm of Department of Irrigation and Drainage Engineering, Dr Annasaheb Shmde College of Agricultural Engineering, M.P.K V, Rahun The filters made from various locally available filter materials were tested for the varying as well as constant suspended load concentration of 200 NTU (285 ppm) Different locally available filter materials viz, sand, angular gravel, pea gravel and coal were tested independently and in combination of two layer, three layer and four layer with varying layer thickness of 15 cm, 30 cm and 45 cm, respectively The effect of filter materials on filtration was studied by recording the observations on inlet head, outlet head, velocity of flow, time of filtration and filtration efficiency The data were analysed statistically. Under varying suspended load concentration in single layer filter maximum filtration efficiency (79.06 %) was found in treatment for sand grade I, with 45 cm thickness The corresponding average velocity of flow and average time of filtration recorded were 191 cm/s and 67 33 min, respectively. The two layer filter sand grade I, recorded maximum filtration efficiency (81 62 %), along with 15 cm layer of coal In case of three layer filter, the maximum filtration efficiency was observed (83 42 %) m angular | en_US |
