SUMMARY:

Over the last decade, several scientific studies have focused on microalgae and its potential. The interest in the massive cultivation of microalgae directly influenced the optimization of photobioreactors treating wastewater rich in nutrients, in addition to the generation of algal by-products. Industrial effluents come from the intense use of water in industries, among the sectors that produce the most wastewater is the starch agro-industrial sector, in Pará the flour mills stand out where the cassava derivatives generated are to supply the industrial sectors of: food, medicine, mining, cosmetics, alcoholic beverages, and others. The effluent that comes from this sector is called manipueira, for the implementation of technologies in this agro-industrial sector, still rustic, a lively interaction between the elements of the social strata is necessary, which are: government, private institutions and universities. In order to reduce the environmental impacts caused by industrial effluent from flour mills (manipueira) and to analyze the feasibility of generating by-products from microalgal biomass, the objective of the present work was to promote the bioremediation of these industrial wastewaters by optimizing the photobioreactor called Immobilized Microalgae Reactor (RMI) operating in hydraulic detention time on a laboratory scale, analyzing its performance regarding the physical-chemical parameters of input and output of the system concomitant with the cultivation of microalgae to verify its potential in the production of biofuels. The RMI operated with a useful volume of 1200mL and as a light source, two LED lamps were used for a period of 24 hours to keep the photosynthetic process of the reactor active, and two dosing pumps were used for feeding flow and system recirculation (RMI) , respectively. Partial results of physicochemical data were obtained in which relevant results for removal of nitrogen (NH4+) and phosphorus (PO43-) and COD were achieved. Since the effluent was obtained within the standards for release into receiving bodies of current Brazilian regulations, there was soon effective bioremediation of the wastewater being treated. It was also possible to identify the genera of microalgae through optical microscopy and use of taxonomic keys, microalgae are from the Chlorophyta division and have relevant quality to be used in the production of biofuels.
