Enhanced Filterability of Fiber Drainage using Wave Energy from Polyvinyldene Fluoride Film(PVDF)

Abstract

Abstract. The use of vibrational energy to enhance the filterability of drainage was investigated with a series of laboratory tests. Test conditions included frequencies, power and duration of sonic energy and curing time. Results indicated that the use of sonic waves in the filtering process significantly enhanced the efficiency of filters. A visible decrease in the flow fouling was also observed. The degree of enhancement varied with sonication energy, and treatment time.
