Contactores biológicos rotativos para el tratamiento de aguas residuales.

Abstract

The rotating biological contactors (RBC), also known as biodiscs, is a reactor that operates under aerobic conditions, designed for the secondary treatment of domestic and industrial wastewater. This system carries out a process of biological treatment, by means of cultures of fixed microorganisms and adhered to the rotating discs of plastic assembled on a horizontal axis, which work as the support forming in them the biopelicula, being this one of greater importance for the development of the system, at the moment in which the biopelicula makes the transformation of organic matter due to the action of the microorganisms that form it, it can be done that as the tributary enters the reactor it can gradually change the microbiological classification . Taking into account other factors that influence the biopelicula that are associated to the chemical composition of the influent to treat as organic load, oxygen availability, temperature, pH and physicists as color, thickness, turbidity and density are considered important to predict the efficiency having consider the characteristics of the water to be treated.
