Title in Portuguese
Simulador de reatores anaeróbios com base no ADM1.
Keywords in Portuguese
ADM1
efluentes
modelos matemáticos
reatores anaeróbios (simulação)
tratamento biológico anaeróbio
Abstract in Portuguese
Primeiramente, esse trabalho pretende esclarecer a importância de pesquisas em modelagem, simulação e controle nos processos de tratamento de efluentes e apontar o atraso do Brasil nesta área de pesquisa comparado ao avanço das iniciativas internacionais. O trabalho apresenta o problema específico da modelagem dos processos anaeróbios e propõe uma nova ferramenta de simulação de regime permanente para esses sistemas, desde digestores de lodo a reatores UASB. O simulador se baseia no ADM1 (Anaerobic Digestion Model No 1), modelo proposto pela IWA em 2002, e está implementado em C++. A intenção é disponibilizar livremente um software de simulação com o diferencial de uma metodologia e interface gráfica amigável, capaz de trazer para o dia-a-dia do profissional da área toda a sofisticação de uma modelagem mais completa, tanto do ponto de vista microbiológico como físico-químico. A metodologia proposta se mostrou muito eficiente para a obtenção da condição de regime permanente, fazendo com que a caracterização do afluente se tornasse a etapa limitante do processo de simulação. O método desenvolvido é tão eficaz que permite que sejam realizadas simulações com afluentes e reatores hipotéticos, tornando possível estudos desvinculados da necessidade de análises laboratoriais complexas ou fora do comum.

Abstract in English
First, this work intends to show the importance of research in modeling, simulation and control of wastewater treatment processes, and to point the delay of our country (Brazil) in this subject, compared to the advance of the international initiatives. This work presents the specific problem of modeling the anaerobic digestion and proposes a new tool to simulate the steady state condition in anaerobic reactors. The simulator is based on the ADM1 (Anaerobic Digestion Model No 1), developed by IWA in 2002, and is implemented in C++. The intention is to give free access to a new simulation software with the advantages of better methodology and friendly graphical interface. This tool should be able to bring to the professionals all the sophistication of a more complete modelling in the microbiological and physical-chemical point of view. The developed methodology revealed itself to be very efficient for the attainment of the steady state condition. Consequently, it makes the characterization of the influent the critic stage of the simulation process. The developed method is so efficient that allows simulation studies to be carried out using hypothetical influents and reactors. Thus, it brings independence for simulation studies with no need of complex or unusual laboratorial analyses.
