Avaliação da eficiência de microalgas na remoção de nitrogênio e fósforo em efluente de indústria cervejeira

Abstract

Chlorella vulgaris is a microalgae capable of growing rapidly in different environmental conditions, is effective in removing heavy metals and excessive nutrients from industrial effluents, to evaluate the use of the microalgae Chlorella vulgaris in the treatment of effluents from the brewing industry, this study analyzed its growth and quantified the biomass obtained, in addition to investigating the reduction of phosphorus and nitrogen. Microalgae was applied to remove heavy metals and nutrients, such as phosphorus and nitrogen, which are used for its growth. This process promoted the improvement of water quality and the generation of rich biomass, with potential for the production of biofuels, biofertilizers and other value-added products. During the experiment, after the initial growth of the microalgae, it was added to the effluent, carried out in duplicate, with samples called A1 and A2. Analyzes carried out at the beginning and end showed a reduction of 97,80% in the concentration of phosphorus and 8,50% of nitrogen, in addition to an increase in biomass. These results indicate the potential of Chlorella vulgaris in the sustainable treatment of industrial effluents, especially to reduce environmental impacts and generate sustainable resources.
