Removal of iron, arsenic and coliform bacteria from water by novel constructed soil filter system

The present paper presents results of the study in removal of iron, arsenic and total coliform from drinking water using single-pass constructed soil filter (CSF). Results indicated that arsenic levels ranged from 0.5 to less than 10 μg l−1 levels; iron from 5 to less than 0.3 mg l−1 and coliform from 10−5 to less than 5 CFU/100 ml. The results revealed very high removal efficiency, i.e., over 99% and water quality as per WHO standard.
