Abstract

Swine wastewater is rich in nitrogen and organic carbon which are essential macronutrients for microalgal growth. Three indigenous microalgal strains (Chlorella sorokiniana AK-1, Chlorella sorokiniana MS-C1, and Chlorella sorokiniana TJ5) were examined for their growth capability in untreated swine wastewater. C. sorokiniana AK-1 showed the best tolerance towards swine wastewater, and obtained the highest biomass concentration (5.45 g/L) and protein productivity (0.27 g/L/d) when grown in 50% strength swine wastewater. Cell immobilization using sponge as the solid carrier further enhanced maximal biomass concentration and protein productivity to 8.08 g/L and 0.272 g/L/d, respectively. Reuse of microalgae loaded sponge resulted in an average biomass production and protein productivity of 6.51 g/L and 0.15 g/L/d, respectively. The COD, TN and TP removal efficiency for the swine wastewater was 90.1, 97.0 and 92.8%, respectively. This innovative swine wastewater treatment method has demonstrated excellent performance on simultaneous swine wastewater treatment and protein-rich microalgal biomass production.
