Abstract

The biological treatment through activated silt is nowadays the most common employed to chasten the sanitary and industrial waste water characterized by contamination with organic charge and nitrogen products. This waste water treatment is widely employed because it is a low coast system and high efficiency rate on BOD and COD remove. The system is composed of a lung tank, to homogenize the charges, aeration tank, responsible for activate microorganisms formation, responsible for biological degradation through oxygen supply, a decanter, employed to decant solids suspended from the waste water treated and a contact tank used to waste water treated disinfection with the aim to remove the pathogenic bacteria. In this work it is presented a study case of a silt treatment station projected to attend 400 people thought activated silt system with conventional aeration and using continuous flow. It was proved through analytical monitoring that the activated silt afford treatments efficiency between 95 and 98%, reducing the pollute charge, which, in most cases, provide conditions to water reuse.
