Project Dates: 2016 to 2019


Network-wide sewer corrosion and odour management is a highly challenging task due to the lack of suitable methodologies to support the control designs of chemical dosing units and sewage pumping stations. This project aims to develop and demonstrate, through real-life field studies, a model predictive control approach that achieves cost-effective network-wide mitigation of hydrogen sulfide. The innovative control methodology involves the simultaneous manipulation of chemical dosing unit(s) and selected sewage pumping station(s), based on real-time prediction of sewage flows and characteristics both at sources and across the network, to ensure optimal delivery of dosed chemicals to realize network-wide mitigation of hydrogen sulfide.
