Advantages of Declining‐Rate Demonstrated
In response to an article in the December 1984 issue of the Journal American Water Works Association, the author of this letter to the editor offers arguments to demonstrate the advantage of the declining‐rate method of filtration. In the declining‐rate system, all filter beds have the same head. The worst filter is not forced to contribute an equal share of the total flow. The contaminated filter does not contribute its share of total flow; hence the head loss is considerably less.
