Automação de biorreatores de membrana utilizando a plataforma arduino

Abstract

With the growth of sewage collection networks, sludge production in Sewage Treatment Plants (ETEs) has been growing steadily as these networks are expanded and new treatment plants are deployed. The sludge generated in the ETEs presents a composition of constituents that can pose risks to the health of the population and the environment, and it is necessary to make adequate final disposal of this residue or to reuse the nutrients that can be obtained in membrane filtration processes. Recent studies have shown that nutrient recovery from sewage sludge can be performed in Anaerobic Membrane - AnMBR systems, which include a feed reservoir, an anaerobic digester, a membrane filtration module and a permeate storage reservoir. Some factors contribute to the performance of the bioreactor process, making constant monitoring of some parameters necessary. The constant monitoring was performed through the automation of the system, using the micro controller Arduino board, connected to pressure and temperature sensors, where values are displayed through reports generated by the software. The software shows information in real time, but also provides a tool where you can query data from the bioreactor according to the desired date. At the end of the research it was possible to verify that the software facilitates the storage and processing of data, offering a better management of information of extreme importance in the aid of decision making in the management of membrane bioreactors.
