TextSeries: Asian Institute of Technology. Thesis ; no. 638Publication details: Bangkok : Asian Institute of Technology, 1974Description: 81 pSubject(s): Online resources: Dissertation note: Thesis (M.Eng.) - Asian Institute of Technology, 1974 Summary: This research attempted to analyze the wastewater treatment sludge handling system in Pepsi Cola Co. Ltd., Bangkok. An investigation of several unit processes for analyzing the sludge .were carried out. The secondary sludges from Pepsi Cola were subjected to gravity thickening, dissolved air flotation tests, aerobic and anaerobic digestion studies and sand bed drying studies. The results obtained for the treatment of this sludge indicated that flotation was more efficient than gravity thickening even the cost is higher than that of gravity thickening. Flotation followed by aerobic digestion and sand bed drying were found more efficient than flotation followed by anaerobic digestion and sand bed drying. The anaerobically and aerobically digested sludges have low fertilizer value.
