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）二期项目的更广泛的影响/商业潜力在于这里提出的卤化乙酸（HAAs）分析仪的能力，它改变了饮用水公用事业主管对饮用水处理厂的理解。HAAs分析仪将允许管理者通过对联邦监管的HAAs（致癌物）进行详细和高质量的测量，持续绘制、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的使用（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、合同操作、咨询/工程、仪器和测试的商业市场规模为193亿美元。整个美国水务行业的市场规模为864亿美元。该提案的主要目标是为美国90%的人口服务的28,643个传统社区供水系统。一些水系统难以满足一级消毒副产物（DBP）规定。这些规定的第二阶段更加严格。DBP法规解决了长期（数十年）暴露于HAAs的问题。管理者可以使用拟议的HAAs分析仪来了解处理厂每小时的短期变化，以提高长期的HAAs最小化。该项目将使首台最先进的仪器商业化，用于对被称为卤乙酸（HAAs）的饮用水消毒副产物进行全自动现场过程监测。本文提出的HAAs分析仪有可能通过减少水处理厂处理化学品的使用来显著降低水处理成本，同时改善和稳定水质，使其不受致癌物和联邦政府监管的HAAs影响。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，而所建议的HAAs分析仪提供的等效每小时数据的开销很大。第二阶段SBIR提案的研究目标是开发HAAs分析仪的组件，使其能够在最少的操作员干预下长期免维护运行。同时，HAAs分析仪的建造和运行成本将降低，以建立商业可行性。预期的结果将是一个HAAs分析仪，它将每小时一次现场自动提供水处理人员的个人和总HAAs浓度。

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.
