Abstract
In this case study of Waste Water Treatment Plants (WWTP) findings show that Activated Sludge technology performs better in categories of Greenhouse Effect, Eutrophication, and Photo-Oxidants Formations; while the Stabilization Ponds have better performance in Air Acidification, Aquatic Toxicity, Depletion of Stratospheric Ozone, Depletion of Abiotic Resources, and Human Toxicity. In Stabilization Ponds the main generator of environmental impacts are emissions produced in the anaerobic processes. The capture and use of these gases produced by the plant could provide alternative energy and reduce impacts. This study evaluates the environmental performance of two WWTPs, as well as in terms of their sustainability.
