Microalgas aplicadas ao tratamento de efluentes oriundos de laticínios

Abstract

The recent growth of the industrial sectors in Brazil is associated with several factors, with the increase in competition among companies being one of the main aspects, generating greater investments, promoting technological innovation and increasing productivity. However, these sectors are directly associated with numerous environmental impacts, being one of this the generation of wastewater from the high amount of water for the manufacture of its products and the sanitation of the equipment present in the processes. These effluents are characterized by the high content of organic matter, composed of easily biodegradable compounds (carbon, nitrogen and phosphorus). In this sense, the use of microalgae for the treatment of effluents from the dairy industry has gained space in the scientific environment, due to algae's ability to remove contaminants mentioned above, and, from this, the possibility of generating valuable products such as proteins, fatty acids, pigments and carbohydrates. In this context, the current work on the conclusion of the course envisages the application of cyanobacteria such as Aphanothece microscopica Nägeli in the treatment of dairy effluents, generating biomass and synthesizing added value by-products.
