dc.description.abstract | This study investigated the growth-dependent role of algal organic matters (AOMs) to achieve high removal efficiency (R.E) of microalgae. The results showed that the microalgae cells produced 96 +/- 2% of total AOMs as loose bound AOMSS (LB-AOMs) and 4 +/- 1% as cell-bound (CB-AOMs) in exponential phase. In stationary phase, LB-AOMs and CB-AOMs were 46 +/- 0.7percentage and 54 +/- 0.2 percentage, respectively. The R.Es in exponential and stationary phase were 83 +/- 2.6% and 66 +/- 1.2%, respectively. It is found that the difference of biomass concentration (between exponential and stationary phase) had no significant impact on the R.E (P > 0.01). Further investigations revealed that LB-AOMs inhibit flocculation in exponential and CB-AOMs in stationary phase; however, CB-AOMs showed stronger inhibition than the LB-AOMs (P < 0.01). The provision of calcium (17 +/- 0.9 mg/L) to the culture reduced the AOMs inhibition and improved the R.E from 66 +/- 1.2% (in control) to 90 +/- 4.2%. An increase in R.E was attributed to the interaction of calcium with AOMs and subsequently acting as a flocculant. The findings of this study can be valuable to improve the performance of auto-flocculation technology, which is mainly limited by the presence of AOMs. | - |
