SBIR Phase I: Evaluating the feasibility of the TotalTHM-NOW for drinking water treatment plants to improve water quality, reduce costs, and lower cancer risks

项目总结/摘要 研究表明，长期饮酒会增加患癌症的风险 含有卤化消毒副产物（DBPs）的水。三卤甲烷（THMs）是最常见的 在水氯化过程中形成的一类卤代消毒副产物。每年，成千上万的饮用水处理 电厂（WTP）与THMs合规性问题作斗争，通常会占用运营预算的很大一部分 采用电气和化学方法来减少THMs的形成。不幸的是，大多数WTP运营商调整 处理过程中没有现场的、实时的THMs浓度数据作为决策的基础， 导致过量的化学品和能量使用以及更高的操作成本。标准方法适用于 季度合规性监控THM，但通常过于昂贵，不适合连续实时监控 监测.虽然有用于现场实时监测THMs的商业设备，但它们并不便宜 大多数WTP我们建议开发我们的前原型TotalTHM-NOW分析仪的商业版本， 价格约为2.5万美元，可为大多数WTP提供实时响应能力，以最大限度地降低THMs浓度 在WTP和分配系统中产生。这降低了社区三卤甲烷的癌症风险 在美国各地，无论大小，农村和城市。TotalTHM-NOW分析仪是全自动的， 为具有与典型WTP人员一致的技能水平的操作员设计。最终，这样做的结果 SBIR提案将确定降低成本的技术可行性，并确定TotalTHM- NOW分析仪在与我们的分析仪进行并行比较研究时提供可靠的THMs浓度数据。 建立了THM-RR系统。

PROJECT SUMMARY/ABSTRACT Research has suggested that there is an increased risk of cancer associated with long-term exposure to drinking water containing halogenated disinfection by-products (DBPs). Trihalomethanes (THMs) are the most common class of halogenated DBPs formed during water chlorination. Every year, thousands of drinking water treatment plants (WTPs) struggle with THMs compliance issues often allocating significant portions of the operating budget towards electrical and chemical means to minimize THMs formation. Unfortunately, most WTP operators adjust treatment processes without having on-site, real-time THMs concentration data to base their decisions on, leading to excess chemical and energy usage and higher operating costs. Standard methods are suitable for quarterly compliance monitoring THMs, but are often too expensive and not well-suited for continuous real-time monitoring. While there are commercial devices for on-site, real-time THMs monitoring they are not affordable to most WTPs. We propose to develop a commercial version of our pre-prototype TotalTHM-NOW analyzer at a price point of ~$25K to provide most WTPs the ability to respond in real-time to minimize THMs concentrations produced at the WTP and in the distribution system. This lowers the risk of cancer from THMs for communities across the Unites States, large and small, rural and metro. The TotalTHM-NOW analyzer is fully automated and is designed for operators with skill levels consistent with typical WTP personnel. Ultimately, the result of this SBIR proposal will be to determine the technical feasibility of reducing costs and establish that the TotalTHM- NOW analyzer provides reliable THMs concentration data in side-by side comparison studies with our established THM-RR system.
