Development of an advanced Control Strategy for chemical dosing in sewers
The process of chemical dosing in sewers for mitigating the effects of odor nuisance and corrosion needs a lot of improvement in terms of on-line control of the variable amount of buffered iron salt that needs to be applied for different operating conditions and different sewage flowrates. In order to achieve this goal, this project aims at developing a lab-scale sewer simulator which operates in a similar manner to sewage water networks. This system will also be modelled and analyzed in terms of the chemical and biological aspects of the process of chemical dosing as well as the typical sewage flow patterns encountered. A control algorithm will be developed and tested that enables this dosing process to happen efficiently so that costly chemicals will not be wasted and hydrogen sulfide effects in sewers will be mitigated.
