Removal of Emerging Contaminants in Drinking Water Treatment

在加拿大，对高水质的需求增加和严格的法规是寻求传统水处理工艺替代品的主要驱动力。此外，废水流出物以及饮用沃茨中内分泌干扰化合物（EDC）和药物活性化合物（PhAC）的检测已经引起了越来越多的关注，涉及用于去除它们的潜在处理方法。 这项研究将检查可能容易在水处理中实施的方法 设施粉末活性炭（PAC）已被用于味道和气味去除几十年，但它也被称为一种去除有机微污染物的方法。拟议的研究将检查PAC去除一系列EDCs，PhAC以及新兴DBP（亚硝胺，卤醌）的能力。此外，它还将提供其他研究人员可能使用的数据，以评估是否应考虑将该技术用于新兴化合物。 超滤，一种现在被采用作为传统过滤的替代方法的做法， 通过将其与PAC结合作为一种混合工艺，作为减少微污染物的一种手段进行了研究。正在开发的评估方法可能随后被水处理公司和顾问采用。

In Canada, an increased demand for high water quality and stringent regulations are the main drivers for seeking alternatives to conventional water treatment processes. In addition, the detection of endocrine disrupting compounds (EDCs) and pharmaceutically active compounds (PhACs) in wastewater effluents as well as drinking waters has brought increasing attention with respect to potential treatment methodologies for their removal. This research will examine methods that may potentially be easily implemented in water treatment facilities. Powdered activated carbon (PAC) has been used for decades for taste and odour removal, however it is also known as a means to remove organic micropollutants. The proposed research will examine the ability of PAC to remove a range of EDCs, PhACs as well precurors to emerging DBP (nitroamines, haloquinones). In addition, it will provide data that may be used by other researchers in assessing whether this technology should be considered for emerging compounds. Ultrafiltration, a practice that is now being adopted as an alternative to conventional filtration, will be examined as a means of micropollutant reduction by combining it as a hybid process with PAC. The methods of assessment being developed may subsequently be adopted by water treatment utilities and consultants.
