Experimental study on double sand filtration system for artificial groundwater recharge
A laboratory study was undertaken in a rectangular filtration chamber having length, width and height as 200 mm, 160 mm and 1200 mm, respectively. Each filter consists of 15 cm thick boulder layer of size 20–40 mm and 15 cm thick gravel layer of size 4.75–10 mm and 10 cm thick. The thicknesses lower course sand (CS) layer of size 0.600–1.18 mm and 10 cm thick upper CS layer each of size 0.425–0.600 mm, 0.300–0.425 mm and 0.150–0.300 mm is placed separately in filters T1, T2 and T3. The influent sediment load prepared by using 0.75–0.15 m soil in terms of concentration as 250, 500, 1000, 1500, 2000, 2500 and 3000 mg/l was used for checking the performance of the filtration system. Various important parameters such as recharge rate, clogging time and removal efficiency of double sand layer filtration system were estimated. The performance of the filter T3 used in present study has also shown better results as compared to filters used in the past for the purpose of artificial recharge of ground water. The proposed filter with treatment T3 is found to be cost effective due to smaller size of the filter as compared to the past studies as well.
