Bioremediation of Power Plant Wastewaters Using Microalgae

Abstract

Industrial wastewater discharge from power plants poses significant environmental risks due to high organic loads, suspended solids, and toxic heavy metals that are inadequately removed by conventional treatment methods. Microalgae-based bioremediation has emerged as a sustainable alternative due to its low energy demand, ability to assimilate nutrients and pollutants, and potential to generate valuable biomass. Chlorella vulgaris is particularly attractive for wastewater treatment owing to its tolerance to harsh conditions and high biosorption capacity.
