WASTEWATER CASE STUDIES AND WHITEPAPERS

WASTEWATER APPLICATION NOTES

  • Optimizing Air Flows To Aeration Basins

    As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

  • Waterworks Joints 101

    There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

  • Pikeville, Kentucky Medical Center Leak Found Despite Ambient Noise

    Leaks found in 60 psi high density PE pipe by FELL in less than three hours. Acoustic and CCTV failed to find any leaks after more than a year of investigation. Read the full case study to learn more. 

  • Waste Technologies Transform Problems To Profit

    Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

  • Municipal Real-Time Water Quality Monitoring

    We arm municipalities with actionable data necessary to make informed decisions about water quality in their communities

  • Application Note: Small Team Saves Big Hassles With The Professional Plus Multiparameter Instrument In the past, Shinkle and her colleagues carried separate YSI meters for pH and DO, she notes. Now they use the YSI Professional Plus handheld multiparameter instrument, which allows them to measure pH, DO and temperature with one quick, reliable instrument. By YSI
  • Recording & Control: Aeration Control In Wastewater Plants – Accurate And Fast Control Of Aeration Process

    Waste water, or raw sewage, is water that drains from toilets, sinks, showers, baths, dishwashers, washing machines and liquid industrial wastes.

  • NEOSEP® Membrane Bioreactor System Simplifies 'Fundamental Necessities' Of MBR

    The NEOSEP® MBR system features Kruger’s uniquely designed K-120C and K-240C flat sheet membrane modules.  The modules offer several innovative design features that enhance ease of installation, operation and maintenance.  This includes an integrated central lifting eye, offering an incredibly well balanced module that makes installation and retrieval a simple and stress-free process.

  • Instruments For Environmental Applications

    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.

  • An Ideal Aeration System For Aquaculture Corporations

    Successful aquaculture corporations know that there are many variables that need to be accounted for in order for the bottom line to be “in the black”, let alone grow annually by 10-20%.

Gardner Denver’s factory-built IQ® PD blower package is a fully integrated package with many energy efficient options, such as Variable Frequency Drive (VFD) and high efficiency motors, which typically operate 3 to 5% more efficiently than standard motors.

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

Veolia’s patent-pending CoStrip degases raw water by introducing microbubbles of a stripping gas (air, nitrogen or fuel gas) counter-current to the liquid stream. First, the microbubbles are introduced into a series of chambers utilizing eductors. Next, they rise and capture dissolved gases due to the disequilibrium between the microbubble gases and the dissolved gases in the water.

There are many different joints that can be found on waterworks pipeline components. This paper focuses on the three most common joints.

Testing for dioxins and PCBs in environmental samples can be challenging due to matrix effects and the need to be able to detect these compounds at very low levels. 

The Dioxin and PCB analysis brochure covers a variety of topics:

  • Dioxin prep system for thorough cleanup with significant time-savings
  • ORBO™-1000 samplers for collecting dioxins/furans and PCBs from air
  • GC columns suitable for analysis of dioxins and PCBs
  • SupraSolv® high quality solvents for trace GC analysis
  • Certified reference materials and analytical standards for accurate analysis

As the final step before treated wastewater leaves the plant, effective disinfection is extremely important to protect human health, and the maintenance of the environment. This process eliminates pathogenic organisms that cannot be removed by previous treatment steps and reduces the spread of pathogens in the natural ecosystem.

USP’s current offerings include our unrivaled in-house CFD modeling expertise that can be used to optimize the injection, mixing and feed rates of PAA to meet the disinfection requirements of a facility. Also, launching later this year, is our OaSys iCT™ is a novel control approach that optimizes disinfection performance by calculating the optimal chemical dosage that accounts for sources of treatment variability in real time. Available for use with PAA or chlorine.

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.
