Overview

Demonstrates enhanced nutrient removal in wastewater via microalgal biomass production, suggesting eco-friendly applications.

Key Points

  • The study aims to evaluate meat-processing wastewater as a resource for microalgal biomass production and its effectiveness in wastewater treatment.
  • Conducted batch assays with microalgae in raw meat-processing wastewater
  • Assessed COD removal rates pre- and post-removal of suspended solids
  • Operated a raceway system in fed-batch mode with treated MPWW
  • Monitored microalgal biomass growth and diversity over time
  • COD removal rates improved from 828.5 to 1097.5 mg L−1 d−1 after pre-removal of suspended solids
  • Up to 806.3 mg L−1 d−1 COD removal achieved continuously in fed-batch mode
  • Total nitrogen decreased in most feeding cycles
  • Microalgal biomass increased from 0.4 to 17.9 µg mL−1
  • Diversity of the microalgae consortium increased, including eukaryotic taxa and protozoan grazers.
