Proposta de um método racional para o dimensionamento de reatores de tratamento de esgotos por lodos ativados em bateladas para remo？？o de carga organica

this paper presents a methodology for the rational sizing of batch operating activated sludge sewage treatment biological reactors for bod removal. developed calculation method computes all the parameters simultaneously involved in the process, modeling the interaction (due to the alternate use of one single tank both as a biological reactor and as a final settling tank) among the factors that determine the treatment unit performance. this work includes a brief review of the literature concerning the subject of the present study, followed by the derivation of the proposed mathematical model, a suggested sizing procedure and an application of the worked out method.
