A total organic carbon (TOC) analyzer is requested to support a research program in drinking water treatment. The analyzer will replace a unit that is failing and can no longer be repaired.Organic matter is ubiquitous in natural waters, and has a major influence on most water treatment processes. For example, the advanced oxidation technologies being studied as part of the research program to be supported by the TOC analyzer are impaired by organic matter, which scavenges hydroxyl radicals that are otherwise used to destroy micropollutants. Organic matter also reacts with chlorine to form potentially toxic byproducts, which can possibly be controlled through some of the techniques being explored in the research. The use of membranes to treat water may be compromised by organic matter which causes the membranes to foul more quickly; or conversely, organic matter can combine with certain dissolved micropollutants such as pharmaceuticals to be removed more effectively by membranes. These are some of the issues being investigated by the applicants, and all require the ability to measure the total amount of organic material present in the water.The outcomes from this work will benefit many sectors of the Canadian drinking water industry, such as manufacturers of membrane or advanced oxidation technologies, municipal practitioners of the technology, and government regulators who must assess the effectiveness of existing treatment methods when introducing new regulations.

总有机碳（TOC）分析仪被要求支持饮用水处理的研究计划。该分析仪将替换出现故障且无法再修复的单元。有机物在自然沃茨中普遍存在，对大多数水处理过程有重大影响。例如，作为TOC分析仪支持的研究计划的一部分，正在研究的高级氧化技术受到有机物质的损害，有机物质清除羟基自由基，否则用于破坏微污染物。有机物也会与氯反应，形成潜在的有毒副产品，这可能通过研究中探索的一些技术来控制。使用膜处理水可能会受到有机物质的损害，这会导致膜更快地结垢;或者相反，有机物质可以与某些溶解的微污染物（例如药物）联合收割机结合，从而被膜更有效地去除。这些都是申请人正在研究的一些问题，并且都需要能够测量水中存在的有机物质的总量。这项工作的结果将使加拿大饮用水行业的许多部门受益，例如膜或高级氧化技术的制造商，该技术的市政从业者，以及政府监管机构，他们在引入新法规时必须评估现有治疗方法的有效性。
