10. Removal of ammonium and phosphate in anaerobiccally treated swine wastewater using biofilm attached cultivation of Chlorella vulgaris

Thanh Phạm Duy, Phương Nguyễn Thị Kiều

Abstract

In this study, the anaerobically treated swine wastewater containing nitrogen and phosphorus is used as culture medium for Chlorella vulgaris. The results of cultivation experiments indicated that Chlorella vulgaris grew well in wastewater containing biofilm and produced a biomass productivity of 1.33 g/m-2 d-1. Biofilm microalgal systems have high nutrient removal efficiency for swine wastewater treatment. The removal ratios of NH4+, PO4-3, and COD are 98.14, 93.70, and 72.16%, respectively. Therefore, it can be concluded that efficient biomass production and nutrients removal in swine wasterwater treatment could be achieved by biofilm attached cultivation of Chlorella vulgaris.
