SBIR Phase II: Evaluating the Feasibility of a fully-automated, on-line, real-time analyzer for simultaneous determination of individual THMs and HAAs

这个小型企业创新研究(SBIR)第二阶段项目的更广泛的影响/商业潜力在于，这里提出的卤代乙酸(HAAS)分析仪能够改变饮用水公用事业主管对其饮用水处理厂的了解方式。HAAS分析仪将允许监督人员对联邦监管的致癌物质HAAs进行详细和高质量的测量，不断绘制、监测并优化他们的饮用水处理实践。使用HAAS分析仪优化水处理实践将减少化学品使用量(节省资金)，同时通过最大限度地减少HAAS为客户提供最高质量的饮用水。美国饮用水化学品、合同运营、咨询/工程、仪器和测试的商业市场价值193亿美元。整个美国水务行业市场规模为864亿美元。该提案的主要目标是为美国90%的人口提供服务的28,643个传统社区供水系统。一些供水系统难以达到第一阶段消毒副产品(DBP)法规的要求。这些规定的第二阶段更加严格。DBP法规针对的是长期(几十年的时间尺度)的哈斯风险敞口。监督可以使用建议的HAAS分析仪了解其处理厂每小时的短期变化，以增强HAAs的长期最小化。该项目将把第一台最先进的仪器商业化，用于全自动、现场监测饮用水消毒副产品卤代乙酸(HAAs)。这里提出的HAAS分析仪有可能通过减少水处理厂的处理化学品使用量来显著降低水处理成本，同时改善和稳定关于致癌和联邦监管的HAAs的水质。目前，大多数饮用水处理厂使用合同实验室来确定分配系统中的HAAs浓度。这种方法可能需要2-3周的时间才能返回结果，与建议的HAAS分析器提供的等效每小时数据相比，成本很高。该第二阶段SBIR方案的研究目标是为HAAS分析仪开发组件，以实现长期、免维护操作，并最大限度地减少操作员干预。同时，HAAS分析仪的建造和运行成本都将降低，以确定商业可行性。预期的结果将是一台HAAS分析仪，它将每小时现场自动提供水处理人员个人和总HAAs浓度一次。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is in the ability of the haloacetic acids (HAAs) analyzer proposed here to change how superintendents of drinking water utilities go about understanding their drinking water treatment plants. The HAAs analyzer will allow superintendents to continuously map, monitor and then optimize their drinking water treatment practices using detailed and high quality measurements on the federally-regulated HAAs, which are carcinogens. Optimizing of the water treatment practices using the HAAs analyzer will reduce chemical usage (save money) while simultaneously providing the highest quality drinking water for their customers by minimizing HAAs. The commercial U.S. market for Drinking Water chemicals, contract operations, consulting/engineering, instrument and testing is $19.3 billion. The entire U.S. Water industry market is $86.4 billion. The major target of this proposal is the 28,643 traditional community water systems serving 90 % of the U.S. population. Some water systems struggled to meet Stage 1 Disinfection By-Product (DBP) regulations. Stage 2 of these regulations is stricter. The DBP regulations address long-term (decades' timescale) exposure to HAAs. Superintendents can use the proposed HAAs analyzer to understand hourly, short-term variations in their treatment plants to enhance long-term minimization of HAAs.This project will commercialize the first state-of-the-art instrument for fully automated, on-site process monitoring of the drinking water disinfection by-products known as haloacetic acids (HAAs). The HAAs analyzer proposed here has the potential to significantly reduce the cost of water treatment through reduction of treatment chemical usage at the water treatment plant while simultaneously improving and stabilizing water quality with respect to the carcinogenic and federally regulated HAAs. Currently, most drinking water treatment plants use contract laboratories to determine HAAs concentrations in the distribution system. This approaches can take 2 - 3 weeks to return the results at a significant expense for the equivalent hourly data provided by the proposed HAAs analyzer. The research objectives for this Phase II SBIR proposal are to develop components for the HAAs analyzer to enable long-term, maintenance free operation with minimal operator intervention. Simultaneously, costs will be reduced for both construction and operation of the HAAs analyzer to establish commercial feasibility. The anticipated results will be a HAAs analyzer that will provide water treatment personnel individual and Total HAAs concentrations once per hour, on-site and automatically.
