Lodo de esgoto como precursor de adsorvente carbonoso a partir do processo de pirólise.

Abstract

The sewage sludge is an abundant biomass waste throughout the world resulting from sewage treatment, it is constituted by a wide variety of organic and inorganic components, making its treatment by complex sewage treatment plants. In a scenario where sludge production tends to increase in recent years due to the increasing number of treated wastewater and sludge limitations of existing disposal means it takes the need for alternative routes to the technological exploitation of this residue in this context, the pyrolysis process is a promising technology that allows production of four fractions with energetic potential: bio-oil, gas, water and solid. The solid fraction in turn addition it can be used as biofuel still has the potential to be applied as the carbonaceous adsorbent low cost. Thereby remedying two problems the sludge disposal and cost reduction of the adsorption process. This paper analyzes on the scientific and technological aspect the State of Implementation of the pyrolysis process the household waste sludge as an alternative technology for the production of carbon adsorbents low cost
