报告内容简介:
The use of chlorine-based methods to disinfect drinking water was a major advancement for public health in the 20th century, as it significantly reduced the risk of waterborne diseases caused by microbes. However, concerns remain about the safety of chlorinated drinking water due to the presence of small amounts of regulated and unregulated disinfection byproducts (DBPs), as well as other known, unknown, and emerging contaminants (KUECs) that can have long-term effects and need to be eliminated. Traditional chemical-based water treatment processes are ineffective in removing DBPs and KUECs, necessitating alternative approaches to minimize these risks. In this presentation, we introduce the "Minus Approach," a novel water treatment method that addresses DBPs and KUECs without compromising microbiological safety. The Minus Approach aims to produce biologically stable water with lower concentrations of KUECs and DBPs while reducing the use of chemical treatments that can cause problems. It focuses on membrane-based physical separation techniques to effectively remove DBP precursors, KUECs, and pathogens from the water treatment process. Implementing the Minus Approach in water treatment improves sustainability by reducing reliance on chemical treatments and minimizing harmful contaminants in treated water.
