Wastewater Case Studies and Whitepapers

  1. How To Revolutionize The Water Industry In 5 Simple Steps

    Turning wastewater into drinking water. Fueling cars with tap water. Installing “waterless” toilets in airport restrooms. Each and every day, people around the globe are trying to transform the water industry in many ways. Here are five steps to help you revolutionize the water industry.

  2. Asset Inspections Are Optimal Tool For Maintenance And Capital Improvement

    Infrastructure asset inspection process is a tool that identifies deficiencies, creates backlog, establishes proactive maintenance, and monitors life cycles; as well as assists agencies in identifying projects for their Capital Improvement Program (CIP). These inspections can provide both a short-term benefit through work identification for repair and maintenance efforts and a long-term benefit of project identification of new capital improvements and enhancement.

  3. White Paper: Passive Filter - Sustainable BMP For Permanent Stormwater Treatment Of Heavy Metals, Nutrients, Hydrocarbons And Sediment
    Passive filtration provides a sustainable alternative to classical drainage concepts for source control of hydrocarbons, heavy metals, and nutrients that endanger our water bodies. In urban areas with high building density, traditional drainage concepts like wetlands are not available and the concept of decentralized treatment facilities that can be housed in catch basin structures are a viable option for treatment of pollutants.

  4. Case Study: Incorporating Innovative Stormwater Management Technologies Into A Sustainable Integrated Use System
    AquaShield, Inc. showcased a sustainable approach to water management using various stormwater treatment and water conservation technologies at their new corporate headquarters in Chattanooga, TN, with Congressman Zach Wamp as the keynote speaker for the event. Working with a blank canvas for a new building and site design, AquaShield decided to put into practice what many just talk about when it comes to implementing environmentally friendly practices.

  5. Roy Hill Iron Ore Optimizes Water Infrastructure Design And Operations For AUD 10 Billion Mining Facility

    In the Pilbara region of Western Australia, 1,200 kilometers northeast of Perth, Roy Hill Iron Ore (Roy Hill) is developing an open pit, bulk mining facility capable of processing 55 megatons of iron ore annually. Set to be the country’s largest iron ore mining operation, the AUD 10 billion project includes a water supply and dewatering network spanning 300 square kilometers that needs continuous adapting to meet the changing mining and ore processing requirements over the 20-year life of the mine (LOM).

  6. Wastewater Treatment Plant Takes A Bite Out Of Tough Solids

    The City of Hammonton’s original steel bar screen rusted while continually allowing debris to pass through to the oxidation ditch and final clarifier. Floatables found their way through the plant to the UV trough, clogging the RAS and internal recycle pumps along the way. Managers of the Hammonton Wastewater Treatment Plant took on the challenge of finding a more efficient screening system. By JWC Environmental

  7. Troubleshooting A Sudden Fecal Coliform Non-Compliance Event

    A municipal wastewater treatment plant investigated a sudden increase in fecal coliform exceedance events.

  8. Do More With Less: Integrating Nutrient Removal Control Improves Treatment Capacity And Efficiency

    Wastewater treatment plants (WWTP) are facing many challenges. Permits on nitrogen and phosphorus in the effluent water are progressively becoming stricter in order to protect surface waters from eutrophication. At the same time, plants are required to reduce both energy and chemical consumption and are often challenged with limited time and staff. In total, they are required to do more with less. In order to meet these challenges, a plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system – the OSCAR process performance optimizer with NURO controller.

  9. ACTIFLO And Hydrotech Discfilter: A Two Stage Process

    The state of Minnesota instituted a new water quality requirement that limits cities along the Minnesota River to a 1 mg/L Total Phosphorus limit by 2015 to prevent algae blooms and resulting pollution problems.

  10. Insta-Valve 250 Patriot Works Under Pressure

    Buchanan County had a project which required repairs to a pumping station that boosts the pressure high enough to get water to a tank at the top of a mountain. The line pressure needed to accomplish this is 250 psi. After considering options, Buchanan County selected the Hydra-Stop Insta-Valve 250 Patriot. Read the full project profile to learn more.
