Overview

Experimental evaluation demonstrates efficient nitrogen and phosphorus removal from digestate using Chlorella sorokiniana, highlighting potential for wastewater treatment in high-latitude regions.

Key Points

  • Green microalgae achieved high nutrient removal of 83% nitrogen and 85% phosphorus from agricultural digestate despite low springtime temperatures.
  • Outdoor cultivation of Chlorella sorokiniana was conducted in pretreated diluted liquid digestate within a covered open raceway pond at a biogas plant.
  • These findings demonstrate that microalgal nutrient removal can support effective wastewater treatment and anaerobic digestion across high-latitude areas.
