| Sumario: | Main filamentous microorganisms have been identified in effluents of sewage from three food industries, which lay on Toluca–Lerma industry zone. This sewage is sent to an industrial company to be treated, its activated sludge process has been affected by filamentous microorganisms identified at the entrance and flow circulation during treatment. In effluents of sewage, the main filamentous microorganisms are: Type 1863, Type 021N, Type 0211, Nostocoida limicola II, Thiothrix I and II y Type 0411, while the main filamentous microorganisms found at the entrance of the sewage treatment company, in addition to those already mentioned, are: Type 0092, Type 0701, Type 0041 y Gallionella. Furthermore, during the flow circulation process not only have all the previous microorganisms been identified, but also the following:Microthrix parvicella (the main and more abundant), Type 1701 and Type 0914. These three last ones are more interesting to study because they only appear during the flow circulation process, giving models to perform a more efficient sewage treatment process. It is concluded that the development of M. parvicella, a filamentous microorganism, affects activated sludge process; the microorganism is created during the flow circulation process by seasonal variations and operational conditions during the treatment process. |
