Removal of Grease from Secondary Effluent by Granular Medium Filtration.
Abstract
The presence of grease in the effluent of secondary wastewater treatment plants is a source of pollution. As such, its removal is desirable. The ability of sand filters, as used in tertiary treatment, to remove grease from secondary effluent is examined in this study. A mixture of secondary effluent and oleic acid, which was added to enhance the grease content of the effluent, was filtered through three high pressure sand filters. During the first stage of the experiment the flowrate through the filters was held constant and the size of the medium was varied. During the second stage the medium size was constant and the flowrate was varied. Samples of the filter influent and effluent were taken and analyzed using a Total Carbon analyzer. (Author)
