✦ Synopsis

An attempt was made to study the physical and biological clogging during artificial recharge with an experimental model that simulates the artificial recharging practice by considering factors such as effective infiltration rate, media size and depth, and inundation period. Recharging was investigated experimentally in terms of suspended solids (S S) removal, 3-day biological oxygen demand (BOD 3) removal and chemical oxygen demand (COD) removal at different sand sizes and infiltration rates. To understand the physical phenomenon involved, the effect of suspended solids concentration and initial infiltration rate on cumulative discharge was studied and verified using a simple mathematical model. The simulated cumulative discharge profiles were comparable with the experimental profiles. This indicates that an empirical relationship can be successfully used to predict the biological clogging at different recharge rates. The effect on headloss was also discussed.

For longtime storage of water in the pores of sand, it is important to study physical clogging. An experimental investigation was conducted using a pilot-scale artificial recharge model to study the temporal and spatial variation of particle retention in the sand pores. The experimental results were
