Pathogen reduction for the purpose of human health protection is a critical function provided by water reuse systems. Pathogen reduction performance potential is dependent on a wide range of design and operational parameters. Poor understanding of pathogen reduction performance has important consequences-under treatment can jeopardize human health, while over treatment can lead to unnecessary costs and environmental impacts. Documented pathogen reduction potential of the unit processes that make up water reuse treatment trains is based on a highly dispersed and unstructured literature, creating an impediment to practitioners looking to design, model or simply better understand these systems. This review presents a database of compiled log reduction values (LRVs) and log reduction credits (LRCs) for unit processes capable of providing some level of pathogen reduction, with a focus on processes suitable for onsite non-potable water reuse systems. Where reported, we have also compiled all relevant design and operational factors associated with the LRVs and LRCs. Overall, we compiled over 1100 individual LRV data entries for 31 unit processes, and LRCs for 8 unit processes. Results show very inconsistent reporting of influencing parameters, representing a limitation to the use of some of the data. As a standalone resource, the database (included as Supplemental Information) provides water reuse practitioners with easy access to LRV and LRC data. The database is also part of a longer-term effort to optimize the balance between human health protection, potential environmental impacts and cost of water reuse treatment trains.
为保护人类健康而进行的病原体去除是水回用系统的一项关键功能。病原体去除性能潜力取决于广泛的设计和运行参数。对病原体去除性能的理解不足会产生重要后果——处理不足会危及人类健康，而过度处理则会导致不必要的成本和环境影响。构成水回用处理流程的各单元工艺已记录在案的病原体去除潜力是基于高度分散且无结构的文献，这给希望设计、建模或只是更好理解这些系统的从业者造成了障碍。本综述展示了一个数据库，其中包含能够实现一定程度病原体去除的单元工艺的累积对数去除值（LRV）和对数去除信用值（LRC），重点关注适用于现场非饮用水回用系统的工艺。在有报告的情况下，我们还汇总了与LRV和LRC相关的所有设计和运行因素。总体而言，我们为31个单元工艺汇总了1100多个单独的LRV数据条目，以及8个单元工艺的LRC。结果表明，影响参数的报告非常不一致，这限制了部分数据的使用。作为一个独立资源，该数据库（作为补充信息包含在内）为水回用从业者提供了便捷的LRV和LRC数据访问途径。该数据库也是一项长期工作的一部分，旨在优化水回用处理流程在保护人类健康、潜在环境影响和成本之间的平衡。
