A laboratory-scale sequencing batch reactor combined with humus soil (HS-SBR) and a sequencing batch reactor (SBR) fed with domestic wastewater were operated to examine the effect of varying sludge retention time (SRT) on the nutrient removal. With 10 days SRT. During acclimatize phase, TP removal efficiency for HS-SBR enhanced and shortened period of time to reaching the steady-state condition. It...
The formation and performance of granular sludge seeded with flocculating sludge was studied in a 4L sequencing batch reactor (SBR) treating a synthetic wastewater with sodium acetate as carbon source. By gradually reducing the settle time from 30 to 10 min, granule sludge was formed on day 20. The granules had a specific gravity of 1.0439, diameters of 0.5-2 mm, and sludge volume index (SVI) of less...
