"TSC has screened and domesticated microalgae and bacteria to establish an algae-bacteria symbiosis (ABS) system. This ABS is highly efficient in photosynthesis to fix carbon dioxide, and its short period of growth and endurance to severe environments resulted in extensive survival in various types of water conditions.

It has demonstrated its effectiveness in treating wastewater with different COD (300-1,200 mg/L) and ammonia nitrogen concentrations (800-900 mg/L). The best degradation rates achieved were COD: 11.1% - 48% and ammonia nitrogen: 37% - 48%. The carbon fixation rate was 0.15g/L/d. This suggests that the system could acquire nutrient sources from wastewater, fix carbon, achieve wastewater purification, and enable resources to be reused. It is a promising technology for wastewater reuse and carbon fixation."
