Life Cycle Assessment to Municipal Wastewater Treatment Plant

摘要

This analysis is a partial study of inventory over a Wastewater Treatment Plant (WTP),rnand establishing the main impacts in the Life Cycle of municipal wastewater treatmentrnsystems with the application of Life Cycle Assessment (LCA) according with ISOrn14040 and ISO 14044. The results showed, in the inventory assessment, an importantrndecreasing in the Biochemical Oxygen Demand and Total suspends solids (75 and 77rnpercent, respectively). On the other hand, it was observed a reduction in Ecotoxicityrncategory in the impacts assessment stage. Finally, consumption of additive and energyrnas well as the generation waste do not imply in a considerable increase of other impacts.
