WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Choosing A Flow Measurement Technology

    Flow, pressure, and temperature are the most important units of measurement when monitoring or controlling fluids in pipes. They are early indicators for problems that can have major implications for the overall business.

  • Case Study: Optimizing Biological Phosphorus Removal From An AquaSBR® System

    Wastewater Treatment Plant located in Middlebury, Vermont treats domestic and industrial waste received from a local dairy and a brewery. Its original treatment system consisted of a flow-through activated sludge process with primary clarifiers, anaerobic digesters, and a four-train Rotating Biological Contactor system.

  • City Of Columbus: Facilities And Safety Training Management

    The City of Columbus entered into a Consent Order with the USEPA to reduce sewer overflows, and 360Water was hired to develop the facilities training and documentation. 

  • Fairbanks Nijhuis Protecting New Orleans

    Originally constructed from the 1920s to 1949, the Gulf Intracoastal Waterway (GIWW) is one of America’s most remarkable transportation arteries. The New Orleans District U.S. Army Corps of Engineers operates and maintains the GIWW in Louisiana, and maintains its six locks for both navigation and agricultural purposes.

  • Efficient And Effective Waste Removal

    Tight timelines, slim budgets and project complexities put a lot of pressure on teams to find the most cost-effective and efficient solutions, especially for high-volume industrial plants. When it comes to water treatment, there is no room for error and there certainly isn’t room in the budget or the schedule for downtime. Innovative and cost-saving solutions are welcome. 

  • Disneyworld Hong Kong Kept Clean By Headworks® MS Sereis Bar Screens

    Children around the world dream of playing with Mickey Mouse or visiting Sleeping Beauty in her castle. This dream became a reality for many children in Asia last year with the opening of Walt Disneyland Hong Kong.

  • Ultrasonic And Radar Level Technologies: Bringing Clarity To The Water And Wastewater Market

    If your head spins after reading how amazing one level measurement technology is in comparison to another, understanding the key attributes of these technologies and their applicability to specific processes may help to clear the waters.

  • Bridging The Gap: Equitable Investment In City Greenspace

    Every year, an estimated 10 trillion gallons of untreated stormwater runoff containing raw sewage, fertilizer, oil, pesticides, bacteria and other pollutants enter U.S. streams, rivers and oceans from city sewer systems, polluting the environment and drinking water supplies. In many urban and suburban areas, this runoff also causes significant flooding.

  • Basics Of Mixing By Submersible Mixers

    Understanding the basics of mixing not only helps wastewater treatment plants (WWTPs) to meet treatment goals but can also reduce operating costs.

  • Improving Total Nitrogen Removal

    To protect the sensitive waters of the Neuse River Basin, the State of North Carolina formally adopted a nutrient management strategy in 1997 which established Total Maximum Daily Loads for all point source contributors of Total Nitrogen (TN) to the Neuse River. By upgrading its oxidation ditches, this Eastern NC plant saw a reduction of 76% TN compared to its average discharge from the past 6 years.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

The OPTIMASS 1400 is a cost-effective twin straight tube Coriolis mass flowmeter for a wide range of standard applications with gases and liquids (up to 170,000 kg/h or 6,235 lb/min). The meter features Entrained Gas Management (EGMTM) for liquid applications, providing reliable readings even in the event of gas entrainment of up to 100%. In this way, the Coriolis meter enables continuous and uninterrupted measurement of volume flow and mass, density and temperature – even at difficult process conditions with 2-phase flow.

The DPI610E is a portable high-accuracy handheld pressure calibrator ideal for engine testing. With 0.025% FS accuracy and a total 1-year uncertainty, it provides stable pressure calibration from vacuum up to 1000 bar. The device is perfect for on-vehicle testing, ensuring accurate calibration and performance monitoring.

In this application note, explore considerations for achieving more reliable accuracy when quantifying dechlorination results for applications ranging from RO membrane protection to wastewater discharge compliance.

Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

U.S. Pipe’s TR-XTREME® pipe is engineered for seismic resilience, providing the first domestic ductile iron pipeline capable of expansion, contraction, and deflection within a single restrained bell joint.

In the battle with hard-to-treat contaminants, drinking water just got a powerful new ally. Leopold Oxelia™ oxidation-enhanced biologically active filtration system.

LATEST INSIGHTS ON WASTEWATER

  • As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.
  • The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.
  • Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.

  • While many scientific and technical reports show that floods are becoming larger and more common, reports underestimate how their frequency is changing. Flood sizes get the spotlight, but governments and experts need to also consider their frequency to address implications overlooked by traditional management methods.
  • In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.

  • Technology like advanced process control systems can streamline operations, create opportunities to lower costs and emissions, and ensure effluent quality meets the highest standards. Research also indicates that implementing an appropriate control strategy can help reduce N2O emissions.
