Abstract

This study focuses on the settling profile and chemical characteristics of latex aerobic granules cultivated from rubber industrial wastewater. Latex-based aerobic granular sludge (AGS) was cultivated using sequencing batch reactor (SBR) in supplemented with synthetic wastewater (SW) as nutrients feeding for biogranulation process. The bioreactor was operated for 24 h with eight series of intermittent 3 h SBR cycles continuously. The SBR configuration comprises of five operation phases from SW feeding, aeration, settling, and effluent decanting to idle. Latex granules exhibit a loose and irregular structure dominated by coccal-shaped bacteria with an average size of 4.0–5.0 mm and a settling velocity of 0.35–0.53 m h^–1. The elemental analysis using X-ray fluorescence (XRF) showed that the latex granules contained various elements while X-Ray diffraction (XRD) analysis suggested the presence of zincowoodwardite, berlinite, rutile, and quartz. Fourier transform infrared spectroscopy (FTIR) analysis revealed the presence of aliphatic hydrocarbons, alkene, alkyne, and tertiary amine.
