Sydney Water's Innovative Approach for Optimising Chemical Dosing Into
ISBN number for Chemeca2019 is 978-1-925627-33-6 Paper no. 23 Chemeca 2019 29 September – 2 October 2019, Sydney, Australia Sydney Water’s innovative approach for optimising chemical dosing into sewer networks Michael Kacprzak 1, Lalitha Parthasarathy1, Rebecca Lockett 1, Luke Walsh 1, Tiffany Chen 1, Gino Iori 1 1. Sydney Water – 20 William Holmes St, Potts Hill 2143 NSW, Australia [email protected] [email protected] [email protected] [email protected] [email protected] [email protected] ABSTRACT For over 130 years, Sydney Water has provided reliable water and wastewater services that are central to liveability. In keeping with Sydney Water’s Lifestream strategy to remain a leading utility, it is essential to pioneer processes to optimise asset performance and improve operational efficiency. A culture of innovation enables Sydney Water to continue to change, adapt and embrace new technologies to stay at the forefront and deliver the best possible outcomes. Hydrogen sulphide (H2S) gas generated in wastewater networks presents a complex management issue worldwide. Corrosion of concrete and metallic sewer assets result in expensive rehabilitation cost, while customer odour complaints and worker health and safety are also major issues. Our aim is to reduce concrete corrosion by minimising the generation and release of H2S with smarter network operation and design. Liquid phase chemical dosing in the wastewater network is integral in achieving this. Sydney Water currently operates more than 65 chemical dosing units (CDU) that dose either ferrous chloride, magnesium hydroxide or calcium nitrate. -

Toxicological Profile for Hydrogen Sulfide and Carbonyl Sulfide
HYDROGEN SULFIDE AND CARBONYL SULFIDE 149 6. POTENTIAL FOR HUMAN EXPOSURE 6.1 OVERVIEW Hydrogen sulfide has been found in at least 34 of the 1,832 waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) and carbonyl sulfide was detected in at least 4 of the 1,832 waste sites (ATSDR 2015). However, the number of sites evaluated for these substances is not known and hydrogen sulfide and carbonyl sulfide are ubiquitous in the atmosphere. The frequency of these sites can be seen in Figures 6-1 and 6-2. Carbonyl sulfide and hydrogen sulfide are principal components in the natural sulfur cycle. Bacteria, fungi, and actinomycetes (a fungus-like bacteria) release hydrogen sulfide during the decomposition of 2- sulfur containing proteins and by the direct reduction of sulfate (SO4 ). Hydrogen sulfide is also emitted from volcanoes, stagnant or polluted waters, and manure or coal pits with low oxygen content (Aneja 1990; Khalil and Ramussen 1984). The majority of carbonyl sulfide that enters the environment is released to air and it is very abundant in the troposphere (Conrad and Meuser 2000; EPA 1994c, 1994d; Meinrat et al. 1992; Simmons et al. 2012; Stimler et al. 2010). It enters the atmosphere from both natural and anthropogenic sources (EPA 1994c, 1994d; Meinrat et al. 1992; Stimler et al. 2010). Carbonyl sulfide is released from wetlands, salt marshes, soil, oceans, deciduous and coniferous trees, and volcanic gases (Blake et al. 2004; EPA 1994c, 1994d; Meinrat et al. 1992; Rasmussen et al. 1982a, 1982b; Stimler et al. -
Sewer Backups
FAQ: Sewer Backups Sewer backups are common but unfortunate problems that occur across the country, including Homewood. Although the Village of Homewood, Department of Public Works, makes every effort to prevent such incidents, backups can still occur. In the event you experience a sewer backup that you believe is coming from the Village’s main sewer line, please call 708-206-3470 or 911 immediately for assistance. The following information is provided to help answer possible questions and provide you with the steps to take if such a problem occurs on your property. Question: What causes a sewer backup? Answer: Clogs or blockages in a sewer line can be caused by materials settling in the pipe, and in turn partially or completely block the sewer pipe. Such blockages can occur either in the Village’s main sewer line or in the private sewer service line, which the property owner owns and maintains. The private line, also known as the lateral line, connects your home or building to the public sewer system. Wastewater from your sinks, showers, toilets, dishwashers, and washing machines flows through the lateral line to the public sewer system. Lateral lines can be blocked or obstructed by items flushed down the toilet or washed down the drain, as well as tree roots, grease and other obstructions. Other causes of sewer backups may include pipe breaks or cracks, tree roots, sewer system deterioration or construction mishaps. When it comes to tree roots, help us help you by making sure not to plant new trees or shrubs over or near your home’s sewer. -
