Hi Ashish,
I suggest you;
(1). Test/analyze your turbid treated water to ascertain the contaminant responsible for the turbidity and then target that in your filter packing/recharge.
(2). Check if your sand is very smooth, then use fine grade on coarse grade after your under-drain gravel, at the bottom.
(3). The analysis of the "turbid treated water" will indicate if you need to include activated carbon, ion exchange resins, etc in your recharge.
(4). Control your backwash flow rate, it is not too good to be very high or very low.
(5). A good filter packing/recharge and on-time/proper backwashing will solve the clogging problems.
Regards.
