Wastewater Case Studies and Whitepapers

81. Jefferson Parish Prevents Odor And Corrosion Issues With BlueInGreen's SDOX-CS Solution 2/1/2021

    Officials at the Jefferson Parish Sewerage Department approached the team at Digital Engineering to find a long-term solution for the odor and corrosion issues throughout the East Bank Wastewater Treatment Plant. 

82. Air Diffusion Systems Helps Francesville With New Aeration System 2/15/2019

    In 2012, the Town of Francesville in Indiana contacted Air Diffusion Systems to provide a solution for several suspended solids violations and energy efficient treatment. Air Diffusion Systems was able to provide an unique solution to correct biochemical oxygen demand (BOD) and total suspended solids (TSS) problems using Kaeser Compressors’ CB Com-paK blowers.

83. BIOSTYR® Improves Health Of The Long Island Sound 6/13/2018

    The New Rochelle Wastewater Treatment Plant is located in the Westchester County, New York, discharging to the Long Island Sound. It serves a population base of 65,000 people and is permitted to treat average flows of up to 20.6 MGD. Operating with primary clarification and pure oxygen-based activated sludge treatment since a 1979 upgrade, the plant only removed BOD and TSS from the wastewater.

84. Automated Solar Sludge Drying Frees Up Personnel 6/6/2017

    Solar dryers are fully automated to feed, move, and discharge biosolids cost-effectively. Even climate changes throughout the year are easily monitored and controlled to produce optimal output. Installation is very flexible with options to add components at a later date. Full automation means employees seldom need to enter the greenhouse and are free to use their time elsewhere.

85. Organic And Nutrient Monitoring For Industrial Process Optimization 3/24/2019

    Beyond community drinking water treatment and wastewater treatment plants dealing with effluent regulatory requirements, many industries also need to concern themselves with organics and/or nutrient monitoring in source water, process flows, or effluent. Here are several ideas for how choosing the right analyzer technology can help optimize both the performance and costs of industrial processes.

86. International Bar Screens Handle Over 6 Billion Gallons Per Day In Detroit 10/5/2015

    In 2004, Headworks Inc. was selected to supply 22 screens to the George W. Kuhn Retention Treatment Basin (“GWK RT Basin”) located in the Detroit Metropolitan Area of Michigan.

87. $0 CAPEX Model Aids Innovation In Changing Water Environments 10/6/2020

    Managers of industrial, municipal, and agricultural water quality or water use monitoring can attest to the challenges of balancing depth of detail against the costs of achieving it. Now, an Infrastructure-as-a-Service (IaaS) business model is rewriting the economic impacts of those challenges by repackaging water monitoring capabilities to meet evolving needs more efficiently.

88. Using Special Repair Fittings To Tame Tough Pipeline Problems 10/1/2019

    For most water utilities, maintaining existing infrastructure — whether planned or in response to emergencies — is a large part of physical plant costs. Being prepared to respond is half the battle. Here are several guidelines and options to consider for maintaining the most cost-efficient solutions to everyday pipeline problems. As with most good plans, they start with proper organization.

89. Hydra-Stop Solutions Isolate Damaged Valve During Water Main Replacement 6/3/2021

    The Village of Covington, Ohio had an ambitious 90-day project to replace the water main, taps, sewer main, laterals, and storm sewer through the center of town. Unfortunately, on day one, an unknown water service line was snagged and the top half of an 8” valve blew off, causing water to shoot 10”–12” out of the street.

90. External Or Internal Flow Meter Verification – An Independent Review 6/1/2020

    To increase the reliability of field devices, some manufacturers equip instruments with internal verification functions based on integrated hardware components. Procedures for the internal testing of devices are not new to the market, but rather a standard feature – at least for MID (European Measuring Instrument Directive) devices. This article looks at the advantages and disadvantages of advanced integrated verification functions for electromagnetic (MAG) flow meters with advanced integrated verification functions compared to external verification.
