Field Study of Generation and Emission of Hydrogen Sulfide in a Sanitary Sewer Network Downstream of a Long Forcemain
Publisher: American Society of Civil Engineers
Abstract: Fieldwork was carried out in the western area of Edmonton, Alberta, Canada to assess the H2S contribution of a long force main and to investigate the source of H2S generation in a complex sewer network. The study sewer ...
Dissolved Oxygen Downstream of an Effluent Outfall in an Ice-Covered River: Natural and Artificial Aeration
Publisher: American Society of Civil Engineers
Abstract: In ice-covered rivers, dissolved oxygen (DO) might fall below critical levels for aquatic biota in the absence of surface aeration, combined with low winter flow conditions and reduced photosynthesis rates. Open-water ...
Sulfide Generation in Force Mains and Its Control Using Nitrate Dosing
Publisher: ASCE
Abstract: Sulfide generation rates in the force mains of four pump stations in Edmonton, Alberta, Canada, were evaluated in the field, and a continuous nitrate dosing was applied in the pump wet well of the Big Lake pump station to ...
