As part of a comprehensive evaluation of posttreatment techniques for algal removal from lagoon effluents, intermittent sand filtration was evaluated. The main objective of the study was to delineate the filtration process most feasible for upgrading lagoons and to identify optimum design and operating parameters. Experimental procedures were conducted at the site of Starkville, Mississippi's 6.1-hectare (15 acre) lagoon. Studies utilized a full-scale sonic microstrainer supplied by FMC Corporation and pilot-sized rapid and intermittent sand filters |
