Model-based optimization of water resource recovery facilities

废水行业正在发生一个重要的变化：范式正在发生转变，从处理废水的行业转变为带来更积极信息的行业：它生产清洁水，并回收“用过的”水中包含的肥料和能源。WRRF旨在提供有价值的产品，这些产品可以部分替代通过其他方式（通常在化学工业中）生产的产品，这一事实导致设施产出规格发生重大变化：不再是处理过的废水和生物固体，而是必须与市场上已有的产品竞争的产品。这些更严格的规范将对保证WRF产品质量所需的过程控制系统提出挑战。由于难以收集控制系统所依赖的高质量数据来对系统进行操作（最近使用部分自动化数据验证的实际研究报告数据丢失5至60%），因此必须部署重要的研究工作来创建始终保持这些严格的产品规格的过程监测和控制系统。

An important change is happening to the wastewater industry: a paradigm shift is occurring from an industry that treats wastewater to an industry that brings a more positive message: it produces clean water, and recovers fertilizers and energy contained in ‘used’ water. The fact that WRRFs aim at delivering valued products that can partially replace those produced by other means (typically in the chemical industry) leads to a big change in specifications of the outputs of the facility: no longer treated wastewater and biosolids, but products that have to compete with what is already on the market. These tighter specifications will impose a challenge on the process control systems that will be required to guarantee the quality of the products of the WRRFs. Given the difficulties in collecting high quality data on which the control systems rely to act upon the system (recent practical studies using partially automated data validation report data losses of 5 to 60%), important research efforts have to be deployed to create the process monitoring and control systems that maintain these tight product specifications at all time.
