Overview

Experimental study demonstrates high nutrient removal from liquid digestate using sunlight-driven microalgae, suggesting an efficient pathway for outdoor wastewater remediation.

Key Points

  • Sunlight-driven treatment achieved 91% soluble chemical oxygen demand reduction and 86% nutrient removal in outdoor liquid digestate, demonstrating high remediation efficiency.
  • Photobioreactor cultivation produced 22 mg/L/d of algae-bacteria biomass while lowering effluent chemical oxygen demand to 735 mg O 2 /L under natural environmental conditions.
  • Microbial analysis demonstrated colonization by Tetradesmus obliquus and Firmicutes, indicating that solar irradiance effectively sustains consortia for wastewater treatment.
