Guía Bioindicadora Para Ingenieros

Abstract

This document presents a general review of the main microorganisms involved in the aerobic treatment of wastewater, basically focused on the activated sludge system, and its relationship with the operating parameters of the system, which influence or condition the presence of these microorganisms. microorganisms. Therefore, images or representations of the most common species will be presented with a brief description of their morphology and the main environmental conditions related to their habitat. The study of this microfauna allows obtaining an understanding of the operational state of the activated sludge system, which makes it a bioindication tool for the aerobic process of wastewater purification. To provide a context for the study of these microorganisms, we will present some generalities of biological systems, especially activated sludge systems; We will describe the most relevant operational parameters of these wastewater treatment systems and, later, we will focus on the presentation of the main species of microorganisms present in the activated sludge.
