A methodology for simulating Hydrogen Sulphide generation in sewer network using EPA SWMM
Desalination and Water Treatment, 2014Co-Authors: Nyoman Marleni, Kyoohong Park, Dimuth Navaratna, Li Shu, Veeriah Jegatheesan, Taehoon Lee, Nam Pham, Antonio FelicianoAbstract:AbstractPredicting Hydrogen Sulphide concentration in sewer network through modelling tools will be beneficial for many stakeholders to design appropriate mitigation strategies. However, the Hydrogen Sulphide modelling in a sewer network is crucially dependent on the hydraulic modelling of the sewer. The establishment of precise Hydrogen Sulphide and hydraulic modelling however requires detailed and accurate information about the sewer network structure and the model parameters. This paper outlines a novel approach for the development of hydraulic and Hydrogen Sulphide modelling to predict the concentration of Hydrogen Sulphide in sewer network. The approach combines the calculation of wastewater generation and implementation of flow routing on the EPA SWMM 5.0 platform to allow hydrodynamic simulations. Dynamic wave routing is used for hydraulic simulations. It is considered to be the best approach to route existing/old sewer flow. The build-up of Hydrogen Sulphide model includes the empirical models of ...

Mitigation strategies of Hydrogen Sulphide emission in sewer networks - A review
International Biodeterioration and Biodegradation, 2014Co-Authors: Kyoohong Park, Hongsik Lee, Shaun Phelan, S. Liyanaarachchi, Nyoman Marleni, Dimuth Navaratna, Veeriah Jegatheesan, Li ShuAbstract:Hydrogen Sulphide (H2S) gas emission in sewer networks is associated with several problems including the release of dangerous odour to the atmosphere and sewer pipe corrosion. The release of odour can endanger public health and corrode sewer pipe walls. Sewer corrosion has the potential to cost water utilities millions of dollars to maintain and rehabilitate the affected sewer pipes. Some chemical mitigation strategies to control Hydrogen Sulphide emission have been introduced. These include but are not limited to the injection of oxygen, magnesium and sodium hydroxide, calcium nitrate and iron salts. The optimisation of the dosing rate and location of each chemical mitigation strategy is required to achieve maximum Hydrogen Sulphide gas removal efficiency along with cost effectiveness. In this review paper, the five most popular chemical mitigation strategies that were previously mentioned have been investigated and discussed. The article is broken down into three main discussions. Firstly the sewer transformation processes and factors affecting the Hydrogen Sulphide generation and emission are highlighted. Secondly, comparisons and differences between each selected chemical mitigation strategy as well as its application covered. Finally, the review of the chemical efficiency and cost is conducted by comparing two case studies in controlling the formation of dissolved Sulphide. It was found that the injection of oxygen is the cheapest mitigation strategy of Hydrogen Sulphide gas generation in sewers, but least effective.
