The goal of the present study is to assess different alternatives for a wastewater treatment plant module with capacity to remove nutrients biologically, taking into account present Argentine regulations for effluent discharge. A computational modeling tool (GPS-X) was employed to simulate the behavior of the different alternatives, and Life Cycle Assessment was applied to quantify the environmental impact. A 2000 m(3)/d municipal wastewater flow was used to carry out the simulations, the annual flow was utilized as functional units and the main topics analyzed were energy efficiency, land use, eutrophication reduction and biosolid reuse. Biogas and biosolid generation was evaluated as a good opportunity to generate a cleaner process. This study highlights the fact that nutrient removal processes significantly improve the quality of effluent and biosolids and reduces energy consumption.
本研究旨在评估具有生物去除营养能力的废水处理厂模块的不同替代方案，同时考虑到阿根廷现行的废水排放法规。采用计算建模工具（GPS-X）模拟不同替代方案的行为，并应用生命周期评估来量化环境影响。使用 2000 m(3)/d 市政废水流量进行模拟，以年流量作为功能单位，主要分析的主题是能源效率、土地利用、富营养化减少和生物固体再利用。沼气和生物固体的产生被评估为产生更清洁过程的良好机会。本研究强调了营养物质去除过程显著改善了废水和生物固体的质量，并降低了能源消耗的事实。
