One of the major barriers to widespread full-scale implementation of anaerobic technologies in mainstream wastewater treatment is the need for modern design parameters to guide utilities’ decision making. Anaerobic technologies are underutilized in wastewater treatment, mistakenly perceived to exclusively treat high strength (e.g. industrial) wastewater or primary and secondary solids in municipal treatment. To contradict these misperceptions, a pilot-scale (720 L) anaerobic baffled reactor was operated by the Colorado School of Mines, continuously treating raw domestic wastewater for 7 years.This paper was presented at WEFTEC 2023 in Chicago, IL.SpeakerCoffey, CarolynPresentation time08:30:0009:00:00Session time08:30:0010:00:00SessionRe-direct Carbon for Better UseSession locationRoom S502 - Level 5TopicEnergy Production, Conservation, and Management, Facility Operations and Maintenance, Intermediate Level, Municipal Wastewater Treatment Design, Research and InnovationTopicEnergy Production, Conservation, and Management, Facility Operations and Maintenance, Intermediate Level, Municipal Wastewater Treatment Design, Research and InnovationAuthor(s)Coffey, CarolynAuthor(s)C.

This technical paper will review the following: National Pollutant Discharge Elimination System (NPDES) permit limits at the Stamford WPCF; Field sampling conducted to understand bacteriological reductions required of the plant’s disinfection process; Bench-scale collimated beam testing for two indicators to inform UV disinfection design dose requirements; Design considerations to ensure compliance with bacteriological limits for fecal coliform and Enterococcus and with a continuous minimum UV dose requirement; and An approach to construction that allowed the plant to maintain continuous operation of the UV disinfection process during replacement of the existing UV system.The Stamford WPCA evaluated alternatives for upgrading and expanding its UV disinfection system at the Stamford Water Pollution Control Facility (WPCF) in Stamford, CT. Primary drivers for this evaluation included planning for compliance with more stringent permit limits for Enterococcus, the need to add standby UV disinfection equipment at the plant's peak design flow, and measures needed to comply with the plant's NPDES permit requirement for the UV dose to always be a minimum 30 mJ/cm2.SpeakerHross, MattPresentation time08:30:0009:00:00Session time08:30:0010:00:00SessionUV Disinfection: Where are we?

The Rosedale Wastewater Treatment Plant in Auckland, New Zealand, consists of primary, secondary, and tertiary treatment and serves a population equivalent of 240,000. After creating a digital twin to support commissioning of a fourth reactor in 2020, it was identified that the digital twin could provide new insights into operational cost and greenhouse gas and support decisionsmaking, to help Watercare achieve their objective to reduce operational greenhouse gas by 50%. Live dashboards were developed to provide new insights into operational greenhouse gas emissions and cost which leveraged real-time biological modelling and emissions monitoring data.

This paper presents a novel design of a fish passage structure for low head dams where conventional type fishways are undesirable or impractical. The hydraulic physical modeling yielded a unique design of a notch in the dam crest combined with three labyrinth (W-shaped) weirs. The notch provides adequate water depth, and the weirs dissipate the flow energy to provide fish with low velocities for passage. For American shad (Alosa sapidissima), the water depth is adequate at minimum river flows, and water velocities are less than the fish burst speeds. The structure complies with the maximum allowable withdrawal at no flow condition over the dam. Weirs provide side openings and center attraction flow. This design is suitable for other low head dams with similar characteristics.This paper provides details on devising an innovative fish passage structure on the Little Falls dam (Potomac River). A unique notch structure in the dam crest provides adequate depth and low flow velocities for the passage of American shad and other migratory fish species.SpeakerOdeh, MufeedPresentation time13:50:0014:10:00Session time13:30:0015:00:00SessionFrom Fish Passage Design to Ocean Discharges: Going CoastalSession locationRoom S402a - Level 4TopicIntermediate Level, Watershed Management, Water Quality, and GroundwaterTopicIntermediate Level, Watershed Management, Water Quality, and GroundwaterAuthor(s)Odeh, MufeedAuthor(s)M.
