Integrated Approach to WWTP Upgrade for Energetic and Efficiency Sustainability

摘要

Wastewater industry primary purpose is obviously to protect surface water quality, aquatic life, beneficial and recreational uses of waterways, and primarily comply with local water emission standards, it should nevertheless also strive to minimize air emissions (such as CO2, methane and nitrogen greenhouse gas), and mitigate other impacts resulting from energy and chemical use in treatment processes. This paper concerns a case study in Europe, where a critical analysis of an industrial WWTP's present shortcomings while evaluating its upgrade to improve regulatory compliance, led to a sustainable proposal of upgrading. According to the formulated proposal, process improvement, energy recovery for local uses, and overall savings and GHGs emission reduction could be simultaneously achieved.
