WASTEWATER CASE STUDIES AND WHITEPAPERS

  • A Natural Approach To Algae Treatment And Prevention

    Operators of lakes, rivers, reservoirs, and other waterbodies commonly introduce harmful chemicals and other compounds — such as antibacterials and bleach — in an attempt to rid the water of problems such as algae and toxins. However, with beneficial bacteria it is possible to achieve a balance in water or discharge by reducing phosphorus and other key parameters naturally, thereby eliminating or drastically reducing the food source for algae.

  • Fox Lake's Wastewater Treatment Plant Retrofit Improves Performance And Increases Capacity

    The existing aerated grit basin (AGB) grit removal system at Fox Lake, IL, was at the end of its useful life and needed to be replaced. There were two requirements for the replacement: they wanted to retrofit the new equipment in the existing area and to eliminate grit deposition in the grit basin which was very difficult to remove. Steve Vella, Fox Lake’s plant Supervisor, saw the HeadCell® at WEFTEC in Chicago. He liked the stacked tray concept, and thought it would be the ideal solution to their plant’s grit problem. He had seen similar operational principles in lamella systems. The stacked tray design would allow them to increase their surface area which would increase their grit system performance, while staying within the existing area used by the AGB.

  • PFAS Remediation: How To Construct A Temporary Solution For A Forever Chemical

    This article will discuss considerations for designing a temporary solution for removing per-and polyfluoroalkyl substances (PFAS) from water, including effective technologies and how to select a solutions provider.

  • AMERICAN's Versatility Shines In Rocky Terrain

    Murfreesboro, Tennessee, is the fastest growing city in Tennessee, and one of the fastest growing cities in the United States with its population more than doubling since 2000. To manage this growth, the city’s Water and Sewer Board recently embarked on an $8.2 million project to construct the Southwest Regional Force Main.

  • How Ultrasonic Sensor Technology Can Increase Processing Plant Efficiency

    In today’s competitive business environment, which focuses on increased throughput, economies of scale and a healthy bottom line, accurate and reliable measurement is a key component. Monitoring production processes by installing a wide range of sensors including flow, level, temperature, and pressure is common and crucial to be competitive. Although there are many reasons why plant managers decide to install monitoring devices in their process, environmental and regulatory reasons dominate one side of the spectrum, whereas quality, process control and monitoring govern the other.

  • Denitrification Technology Significantly Improves Polluted Chesapeake Bay Watershed

    The 64,000 sq ft Chesapeake Bay Watershed includes parts of MD, VA, WV, PA, and NY. Of the 1,000s of WWTPs supporting nearly 18 million people in the watershed, 470 are designated by EPA as significant sources of nutrients and TSS. Algal blooms reduce DO levels in the water, killing plant and animal life — from marsh grasses to blue crabs to rockfish. Learn how De Nora TETRA Denite technology is treating 450+ MGD in the Bay.

  • Using Supersaturated Oxygen Solutions To Suppress Sulfides And Control Odor

    This is the third article in a series of articles and case studies examining the adoption of innovative solutions in water treatment and the market drivers of change influencing how companies in various industries manage their wastewater.

  • Preventing Algal Blooms With A “Pinch Of Sugar”

    Have you ever walked or driven by a lake covered with a thick scum that looks like pea soup? This could be caused by blue-green algae, a cyanobacteria (“cyan” means “blue-green”) that is frequently found in freshwater ponds and lakes. Cyanobacteria are often confused with green algae because both can produce dense mats that may smell bad and hamper activities like swimming and fishing. However, unlike most green algae, blue-green algae can produce cyanobacterial harmful algal blooms (cyanoHABs). The highly potent toxins they make, called cyanotoxins, can harm people, animals, aquatic ecosystems, the economy, drinking water supplies, property values, and recreational activities.

  • Growing Need For Sustainable Water Management Drives Increased Demand For Water Analyzers

    ABB in the UK saw a 50 percent increase in the sales of its Aztec 600 water quality analyzers in 2023 compared to the previous year as British water utilities worked to ensure more sustainable management of potable and wastewater supplies, as well as compliance with water quality and environmental regulations.

  • Anaerobic Digestion Optimization System Provides Exceptional Improvements

    Faced with soaring ammonia loads—especially during race weekends when 250,000+ fans descend on the town—the Speedway, Indiana Wastewater Treatment Plant was in urgent need of a solution.

WASTEWATER APPLICATION NOTES

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.
