Granule size informs the characteristics and performance of microalgal-bacterial granular sludge for wastewater treatment

In this study, four groups of microalgal-bacterial granules with averaged diameters of about 356, 760, 951 and 1,444 µm were used to investigate their characteristics and performance in treating wastewater. A strong correlation between extracellular polymeric substances of microalgal-bacterial granu...
