Abstract

With the growth of the world population, in recent decades, the generation of domestic sewage has increased. In Brazil about 28 million cubic meters of sewage are generated daily and needs to be collected and treated. This task has been one of the biggest challenges for municipal administrators. Disposition of domestic sewage without treatment is a risk to public health and environment. This paper presents scenarios for treatment of domestic sewage with energy recovery and minimization of environmental impacts based on the biodigestion and incineration with the objective of demonstrating to the public administrators the economic and environmental energy potential. The results show that the electrical energy from the biodigestion of sewage sludge is equivalent to the consumption of 1.5 million households and electricity resulting from incineration corresponds to consumption of 1.3 million homes while the emissions are about 0.875 MtCO2 per year compared to 3.585 MtCO2/year released in the biological treatment. In addition, in both processes of treatments, it is possible to recover half of the volume of wastewater for reuse. In this way, adequate treatment of domestic sewage can protect the environment from the drastic charges of sewage while being a source of energy and water, which are indispensable assets for maintenance of life on the planet.
