This paper aims at exploring the feasibility of adsorption filtration technology using reclaimed iron sludge coated sand (RISCS) as filter media for municipal wastewater reuse. The iron sludge as surplus waste solution derived from ferric-carbon micro-electrolysis process. Scanning electron microscope (SEM), Infrared spectroscopy (IR) and X-ray diffraction (XRD) analysis were used to investigate the...
The pilot plant study comprised the sequencing batch reactor (SBR) operational mode of a contact oxidation filtration separation integrated bioreactor (CFBR) for treating municipal wastewater. The CFBR was made up of an upper biofilm reactor and a lower gravitational filtration bed. Polyacrylonitrile balls (50mm diameter, 237 m2/m3 specific surface, 90% porosity, and 50.2% packing rate) were filled...
The object of this study is to investigate the sintering processes of sewage sludge ceramic pellets (SSCP) as filter media. The effects of adding coal fly ash and farmland clay were tested, and the feasibility of using SSCPs in a biological aerated filter (BAF) was determined by comparing their performance with that of commercial ceramic pellets (CCP). Unlike the procedure to make lightweight sewage...
