Sustainable and Green Management of Wastewater Under Climate Change Conditions

Abstract

Climate change affects significantly the natural water cycle in many locations as projected for the future. Due to the increasing scarcity of water resources, reusing wastewater will become more crucial especially because of climate change acceleration. As well, climate change is one of the main challenges to wastewater treatment systems in the future. On the other hand, greenhouse gas (GHGs) emissions during wastewater treatment can be released into the atmosphere (such as carbon dioxide (CO2) that results from (oxidation processes), methane (CH4) that results from anaerobic processes, and nitrous oxide (N2O) associated with nitrification and denitrification processes). The water demand increased per capita due to the pressures associated with population growth. Thus, many researchers try to address sustainable and green water management approaches that can state the root causes of such challenges. This not only mitigates the climate change impacts on water resources but also facilities using treated wastewater safely in sustainable and greenways.
