handling turbidity and sediments during monsoon periods

This is often a problem of handling turbidity and sediments during monsoon periods. Basically one should know the required volume of turbid water to be treated for use.  Several field trials are available and one should note the time required for removing turbidity with the use of conventional alum (aluminium sulphate), ferric coagulants with lime etc., however the use of those are limited in the recent times due to sludge handling and health implications. Of course coagulation method is not the only method, but relatively easier, efficient and cost effective. For household level, to be cheap,  one can adopt simple lime solution, then with bleaching & cloth filtration, eventually the settled residue to be removed . One can exercise simple options out of  their own repeated trials and be satisfied with the quality of clarified water.
