Replacing DP transmitters with 80 GHz radar eliminates density errors, reduces maintenance, and simplifies installation — delivering safer, more reliable level measurement for modern wastewater systems.

WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Grinders, Shredders And Comminutors – An Evolving Technology

    Comminution technology has been evolving quite rapidly in response to the increasing burden entrained solids have placed on treatment facilities. More advanced devices have been developed in rapid succession. The result has been an exciting and fluid race between the leading manufacturers to develop the best size reduction device. The latest grinder innovations to be introduced have coupled the power of twin shaft grinding with higher flow capabilities and screw screening systems. Here’s a rundown on the past and present state of the art in wastewater solids reduction.

  • Proper Care And Calibration Of pH Sensors

    Here are some guidelines for everyday care, regular maintenance, and periodic calibration or replacement to assure optimum performance of pH instrumentation.

  • What's Missing From Your Water-Monitoring Strategy?

    When it comes to water quality monitoring, professionals in municipal, industrial, and agricultural applications might have distinctly different concerns about what they measure, but they all share a common concern about the cost and ease of obtaining that data. Fortunately, a new alternative for achieving water quality data and analytics with a high degree of autonomy, accuracy, and affordability is now available to all of them.

  • Evansville, IN Deploys Real-Time Decision Support System To Cut CSOs By 100 Million Gallons And Reduce Capital Needed For Regulatory Compliance

    Evansville is located on the north bank of the Ohio River in southwest Indiana. The City’s sewer system, parts of which are more than 100 years old, serves a population of 163,000, with combined sewers making up almost 40 percent of the total sewer area.

  • Decentralized Wastewater Treatment In A Housing Development

    Young’s Cove is a masterfully planned exceptional waterfront community situated in pristine Prince Edward County, on the shores of Lake Ontario. It has panoramic views, a children’s waterpark, miles of pathways, green spaces. It covers 7,000 feet of shoreline and fronts protected wetlands and preserves hundreds of acres of forest with birds and wildlife everywhere.

  • 5 Common Wastewater Challenges And How To Mitigate Them

    From ragging and grit to odors and cost constraints, wastewater operators face persistent challenges. Proven headworks technologies and preventative maintenance help utilities improve performance, reduce downtime, and control costs.

  • Pipe Repair: Emergency Response In Compton

    When the Sanitation Districts of Los Angeles County (LACSD) were formed in the 1920s, the agency embarked on its first major project -- the construction of the backbone trunk sewer of the Joint Outfall System (JOS). Since then, the Sanitation Districts have completed many challenging projects, providing environmentally sound, cost-effective wastewater and solid waste management services to over five million people in Los Angeles County.

  • Avoiding Unplanned Outages In Water Treatment

    Maintenance professionals within Water and Wastewater Treatment facilities are as busy as ever. To keep up with growing demands on their time, they are always looking for ways to improve the reliability and maintenance requirements within their scope of responsibility.

  • The DELUMPER®: A Sweet Success At ADM

    ADM Cocoa Plant in Hazle Township, Pennsylvania needed help with their cocoa bean production. The plant processes two and a half million pounds of cocoa beans each day, turning them into cocoa powder, cocoa butter, and chocolate liquor. The company needed a machine to process sugar with over-sized lumps that could occur in transport or storage. Unless these agglomerated clumps were reduced to a granular form, the process could not work dependably. The machine also had to handle the large quantity of sugar processed daily and be sanitary.

  • Maintaining Greater Value In Bar Screen Performance

    Before wastewater can be treated to minimize biochemical oxygen demand (BOD), nutrients, and pathogens, it is important to eliminate as much debris as practical, as early on in the treatment plant as possible, to avoid clogging pumps or compromising downstream performance. Careful consideration of design and operating factors can minimize total lifecycle costs and maintenance effort while protecting screening efficiency.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

DELUMPER® LP crushers reduce hard or soft, heat sensitive, sticky or wet agglomerates and lumps at high volume. These straight-through units employ extended cutting teeth that rotate completely through a heavy bar cage. Oversized solids up to the unit’s full input opening size are reduced by this powerful processor. With each rotation, the teeth clean the slot openings making the unit automatically self-clearing. Optional hardfacing is available.

Drying of sewage sludge has to meet the conflicting demands between economic efficiency, energy supply, product requirements, disposal safety and utilization options. Drying of sewage sludge minimizes its mass, volume and disposal costs. The produced dry and disinfected biosolids are a valuable product that is well suited for its beneficial use. Different energy sources can be used to supply the heat required for drying. Huber uses a medium temperature design using temperatures up to 293 °F. This is because these temperatures are high enough to ensure quick drying and at the same time provide a cost-effective and eco-friendly utilization of waste heat. Internal recycling of dryer air via a condensator with integrated heat recovery reduces the heat demand of the dryer even more.

This application note from Aqua-Aerobic Systems highlights the effectiveness of the AquaStorm® Cloth Media Filter as a flexible, compact, and highly efficient solution for Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) events.

The JCS Industries Model 420-Cylinder Mounted Regulator is designed for years of safe and reliable service.

QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.

The PAX Mixer design is based on rigorous scientific analysis of fluid mechanical principles to achieve rapid disinfectant blend time. The mixers are designed for energy efficiency and engineered for ease of installation.

LATEST INSIGHTS ON WASTEWATER

  • With the rise of water scarcity, environmental regulations, and corporate sustainability mandates, produced water treatment has become a strategic imperative for industries far beyond oil and gas. It is one of the fastest-growing segments in the water treatment industry, which has emerged as an amalgamation of environmental stewardship, regulatory compliance, and technological innovation.
  • People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.
  • 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.
