Over the years, wastewater treatment objectives have become more stringent. These objectives demand more energy and higher wastewater treatment operating costs. These increasing costs coupled with emerging sustainability requirements are propelling researchers, industry, and utilities to come up with more efficient ways of managing wastewater. Mainstream wastewater treatment has undergone a paradigm shift; parties now emphasize wastewater energy recovery and the concurrent reduction of energy consumption. This shift enables wastewater treatment plants to achieve energy neutrality while meeting treatment objectives. Despite extensive effort and rapid technological advances, demonstrating mainstream energy neutrality is still challenging due to the diluted nature and lower operating temperature characterizing mainstream wastewater. Other challenges include process complexity, knowledge gaps in process control and the lack of robust technologies.

多年来，废水处理目标变得越来越严格。这些目标需要更多的能源和更高的废水处理成本。这些增加的成本加上新兴的可持续性要求，推动了研究人员，行业和公用事业，以提出更有效的管理废水方法。主流的废水处理经历了范式转移。各方现在强调废水能源回收和同时减少能源消耗。这种转变使废水处理厂能够在达到治疗目标的同时达到能量中立。尽管大力努力和快速的技术进步，但由于稀释性质和较低的工作温度表征了主流废水，证明主流能量中立仍然具有挑战性。其他挑战包括过程复杂性，过程控制中的知识差距以及缺乏强大的技术。
