本幻灯片演示概述了东湾市政公用事业区（EBMUD）的大型系统消毒替代方案，以实现长期合规性。演示大纲包括EBMUD水系统概述、权衡和挑战、当前系统性能、消毒目标以及EBMUD的长期战略。EBMUD面临的具体挑战包括: 病原体灭活（CT）；消毒副产物 （DBPs）（新法规，对 急性影响、新兴DBP等）； 开放盆地藻类生长、生物膜； 危险品管理； 向环境排放； 同时合规性（Mn、LCR）；和 残余维持/硝化作用。此外，还提供了EBMUD的消毒和水质目标。

This slide presentation outlines East Bay Municipal Utility District's (EBMUD) large system disinfection alternatives for long-term compliance. The presentation outline includes EBMUD Water System overview, trade-offs and challenges, current system performance, disinfection goals, and EBMUD's long-term strategy. Specific EBMUD challenges include: pathogen inactivation (CT); disinfection byproducts (DBPs) (new regulations, concerns over acute impacts, emerging DBPs, etc.); open basin algae growth, biofilm; hazardous material management; discharges to environment; simultaneous compliance (Mn,LCR); and, residual maintenance/nitrification. Also, EBMUD's disinfection and water quality goals are provided.
