Recent development in direct filtration

American Water Works Association Journal 72(3): 165-169

Recent development in direct filtration

Color removal, ozonation as a pretreatment, and scanning electron microscopy are among the recent developments in direct filtration which extend the applicability of the process as an economical means of meeting turbidity standards.
