EV-87-19Publication details: Bangkok : Asian Institute of Technology, 1987Description: 64 pSubject(s): Online resources: Dissertation note: Thesis (M.Eng.) - Asian Institute of Technology, 1987 Summary: This research aims to innovate slow sand filter process in its purification capacity to treat surface waters for a drinking purpose . The experiment was performed by using locally available jute fabric to overlay sand bed . The filter was operated at filtration rates of 0. 2, 0. 4 an d 0. 6 m3/ m2- h . Jute-fiber h ad retained more than 86 percent of influent suspended solids (SS) that increased the filter run of the sand bed. However, jute fiber release d TOC a nd tot al solids (TS) t o the filtrate that it resulted in l ow efficiencies in TOC an d TS removal. Coliform bacteria were removed significantly but Further dis infection was needed for drinking purpose. Also, removal of iron and manganese were highly efficient.
