WASTEWATER CASE STUDIES AND WHITEPAPERS

  • The Benefits Of A Venturi Meter

    With the introduction of new measurement technologies and the myriad of performance claims from sale literature, it’s easy to lose sight of the important elements that an effective flow meter offers no matter what technology is used. Long known for their longevity, reliability, and long term performance, Venturi meters provide the widest variety of measurement options in piped systems for liquids, gas, steam, and mixed media of any metering technology – all while offering the highest degree of traceable accuracy.

  • EPA Tool Simplifies Stormwater Decision-Making

    Communities are facing decisions on how best to upgrade aging stormwater infrastructure and build new  infrastructure to lessen the impacts of stormwater runoff. As communities make these decisions, they need tools to assess their options in order to determine the most cost-effective approach.

  • The Proper Application Of Rotary Lobe And Rotary Screw Blower Technology

    Written by Kaeser’s system experts, this white paper compares rotary lobe and screw blowers, isochoric and isentropic compression, and how to properly apply these technologies for designing an energy efficient system.

  • Aire-O2's Cold Weather Legacy

    Bose Cascade’s Ft. Frances, Ontario kraft mill operation faced a wastewater treatment problem due to dead spots in nearly half of its aerated stabilization basin. Newterra's Aire-O2 came to the rescue.

  • The "Design For Autonomous Net-Zero Water Buildings" Project Funded By NSF

    The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water.

  • Advanced On-Site Wastewater Treatment For Greenfield And Retrofit Applications

    Many owners and operators of traditional decentralized municipal wastewater treatment plants, also referred to as on-site or off-grid treatment, are acutely aware their systems are at risk of becoming obsolete.

  • How To Cannibalize Your Own Technology

    Business people love to talk about "disruption." They pride themselves on eating their competitors' lunch. Where their markets used to be about raving fans, now it's about inspiring craving fans, fueled by "hunger marketing" and the fear of missing out. There's a lot of dog-eat-dog philosophy...which is why it's important for companies to be willing to cannibalize their own technologies.

  • AOP Removal In Aquifer Remediation

    In this case study, read about a successful pilot test in Long Island, New York, removing 1,4 dioxane from water. The technology used offers improved efficiency, reduced maintenance, and ongoing monitoring for reliable water treatment.

  • Case Study: Chemical Company Achieves Compliance While Pretreating Water For Use On Public Golf Course A worker at Millennium Specialty Chemicals of Jacksonville, Fla. monitors a cooling water tank gauge.
  • Sewer Authority Ends Plant Bypasses And Introduces Nutrient Removal With New Treatment Process

    Find out how a treatment plant upgraded its secondary treatment aeration system to include nutrient removal through a nitrification/denitrification/phosphorus process and has successfully processed I&I induced surges that reached a 10-MGD peak.

WASTEWATER APPLICATION NOTES

WASTEWATER PRODUCTS

The Davco™ product line of Evoqua located in Thomasville, GA, offers retrofit, rehab, and replacement parts and services and the installation of water and wastewater filtration, separation, clarification, aeration, biological treatment, and screw pumps. Our retrofit and rehab services save municipal and industrial water and wastewater plants time and budget in addressing worn out, over-extended-in-capacity treatment facilities that are costly to maintain.

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

The OPTIFLUX 2300 is an electromagnetic flowmeter (EMF) for all demanding applications with water and wastewater. The high-end meter is particularly suitable for applications requiring high accuracy and extensive diagnostics.

The OPTIMASS 3400 is a cost-effective Coriolis mass flowmeter for accurate flow measurement of liquids and gases in a variety of demanding low flow and dosing applications (from 0.3 kg/h or 0.01 lb/min upwards). The OPTIMASS 3400 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 very difficult process conditions with 2-phase flow.

DEMON® is the continuous or SBR deammonification process utilizing granular anaerobic ammonium oxidizing bacteria (anammox) biomass for aiding in reduction of high strength ammonia from side stream solids dewatering facilities reject flows. World Water Works’ DEMON process can solve the problem of returning high concentrations of ammonia to the plant influent. The true key to the success of the technology is the patented advanced biological process controls and the physical separation used to facilitate the growth and retention of the anammox bacteria.

The EscaMax® is particularly well suited in situations where excellent separation efficiency is required in deep channels with high water levels. The sturdy EscaMax® screen is able to reliably cope with high amounts of gravel and grit. The two-dimensional screening elements prevent especially long fibres from passing through the screen and thus achieve the maximum separation efficiency.

LATEST INSIGHTS ON WASTEWATER

  • Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.

  • Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.

  • Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.

  • Learn key ozone formulas, unit conversions, and measurement standards to accurately calculate generator output, concentration, and dosage for effective system design, performance verification, and safe operation.

  • In an industrial landscape increasingly shaped by lifecycle accountability, material traceability, and rising disposal costs, chromium recovery is not merely a technical alternative — it is a strategic upgrade, where wastewater can become a resource stream.
  • 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.
