STTR Phase I: Ultraviolet Activated Chelation (UVAC) for the Recovery of Hg from Industrial Wastewater

这个小型企业技术转让第一阶段项目的重点是开发一种先进的氧化技术，以满足当前和即将出台的关于工业废水中汞浓度的规定。在目前的项目中，将使用一种专有的光催化剂来研究氧化和去除汞的能力。该项目的研究目标将是更好地了解去除过程，使用这种方法优化汞的去除，并确定未来发展所需的参数。通过拟议的方法，汞浓度预计将低于100ppt。与传统的水处理技术相比，该方法具有从各种不同的废水中去除汞的能力，并且需要更少的运行和维护成本。汞排放，无论是来自空气排放还是工业废水，都严重威胁生态系统和渔业。通常，环境技术被视为环境合规的必需品，而不是对其利润报表产生积极影响。拟议的方法可能会改变这种观点；这一过程可能会从该行业的大宗商品腐蚀性产品中去除汞。

This Small Business Technology Transfer Phase I project focuses on developing an advanced oxidation technology to meet current and pending regulations for concentrations of mercury that can be emitted in industrial wastewaters. In the current project, a proprietary photocatalyst will be used to investigate the ability to oxidize and remove the Hg. The research objectives of this project will be to better understand the removal process, to optimize the removal of mercury using this approach, and to define the parameters necessary for future development. Mercury concentrations below 100 ppt are anticipated via the proposed approach. The approach has the robustness to remove Hg from a variety of different waste streams and requires less O&M costs than traditional water treatment technologies. Mercury emissions, whether originating from air emissions or industrial effluents severely threaten the ecosystem and the fishing industry. Typically, environmental technologies are viewed as necessities for environmental compliance, and not as positively impacting their profit statements. The proposed approach can potentially alter this view; this process could possibly remove Hg from caustic, a commodity product for the industry.
