| Abstract |
The paper was prepared as a review of slow sand filtration design and operating practices at 13 filtration plants constructed between 1958 and 1988 in the Pacific Northwest. It represents an attempt to learn from the past in order to do a better job in the future. Among the topics presented are plant construction features, including media characteristics, filter design, and hydraulics; water quality; and operation and maintenance practices. Narrative descriptions of each plant are given, and some specific design and operating examples are presented. Data from the plants have been tabulated so that frequently observed or common characteristics of design and operation can be noted. Finally, some comments are made about recent design and operating practices, in order to assist those who will design or operate slow sand filters in coming years. |
