牙科诊所的汞（Hg）释放已成为牙科行业的一个严重问题，并导致监管机构努力要求使用最佳管理实践（BMP）以及安装汞合金分离器。一些人对汞合金分离器在减少废水处理厂汞负荷方面的效果表示关切。来自几个公共处理厂（POTW）的数据表明，这些设备可以大大减少污水处理厂的汞负担。这些数据包括下水道污泥（生物固体）中的汞含量，在某些情况下还包括污水处理厂流入物和流出物中的汞浓度。数据来自不同的地理位置，表明分离器可以在减少进入污水处理厂的汞量方面产生积极影响。
Mercury (Hg) release from dental offices has become an acute issue for the dental profession and has resulted in efforts by regulators to mandate both the use of Best Management Practices (BMPs) as well as the installation of amalgam separators. Concern has been expressed by some regarding the efficacy of amalgam separators in reducing the Hg loads to wastewater treatment plants (WWTPs). Data from several Publicly Owned Treatment Works (POTWs) serving areas with installed bases of separators suggest these devices can substantially reduce Hg burdens to WWTPs. The data consists of Hg levels in sewer sludge (biosolids) and in some cases includes Hg concentrations in WWTP influent and effluent. Data comes from various geographical locations, and suggest separators can have a positive effect in reducing the amount of Hg reaching WWTPs.
