Overview

Randomized trial identifies effective microalgae strains for nutrient removal in brewery effluents, suggesting sustainable alternatives.

Key Points

  • The study aims to identify effective combinations of brewery effluents and microalgae strains for improved nutrient removal and biomass production.
  • Five brewery effluents were evaluated as microalgae media, including raw and treated wastewater stages.
  • Batch experiments were conducted with Scenedesmus sp. in pre-acidification effluent for biomass production and nutrient analysis.
  • Nutrient removal efficiencies for phosphate, total organic carbon, and total nitrogen were measured.
  • Scenedesmus sp. cultivated in pre-acidification effluent achieved biomass production of 0.93 g/L.
  • Removal efficiencies were 100% for phosphate, 81% for total organic carbon, and 68% for total nitrogen.
  • The microalgae-bacteria consortia demonstrated potential to replace conventional wastewater treatments, reducing COD below discharge limits.
