Abstract
Currently, algae have been focused on research to apply in different fields. With the desire to contribute to the application of microbiological technology to reduce pollution in organically polluted wastewater per the situation of Vietnam, this study is conducted to apply Actinastrum sp. to treat nitrogen and phosphorus in swine wastewater after biogas digesters. Empirical results suggest that the algae are capable of treating livestock wastewater, meeting the standards of national regulation QCVN 62-MT:2016/BTNMT with maximum COD and TN removal of 84.62% and 81.88%, respectively, when supplemented with an algal density of 2.5x10^6 cells/mL.
