This project plans to use a newly discovered, low-cost and environmental benign antimicrobial agent to develop an innovative technology to control the development of corrosion-inducing sewer biofilms. Concrete sewer corrosion is a long-standing and costly problem for the water industry. Microbial hydrogen sulfide oxidation on concrete surfaces plays a critical role. The technology will be designed to prevent corrosion of new concrete sewers by adding a precursor chemical into the cement, or to slow down the corrosion of existing sewers by infrequently (once every one to few years) spraying the precursor chemical directly onto the concrete surface. Potentially, the project will substantially reduce sewer corrosion.

该项目计划使用一种新发现的低成本、环境友好的抗菌剂来开发一种创新技术，以控制导致腐蚀的下水道生物膜的发展。混凝土下水道腐蚀是自来水行业长期存在且代价高昂的问题。微生物对混凝土表面的硫化氢氧化起着至关重要的作用。这项技术旨在通过在水泥中添加前体化学品来防止新混凝土污水管道的腐蚀，或者通过不频繁地(每隔一到几年)将前体化学品直接喷洒到混凝土表面来减缓现有污水管道的腐蚀。潜在地，该项目将大大减少下水道的腐蚀。
