WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Biologically Active Filter Technology Applications For Wastewater Treatment Upgrade

    Wastewater treatment facilities are subject to many different drivers for completing upgrades. Among the most prevalent drivers is a need to keep current with ever-changing, and increasingly stringent, environmental regulations. These regulations frequently require upgrading to tertiary treatment and the removal of BOD, TSS and Total Nitrogen.

  • Providing Pumping & Control Equipment To Reduce Force Main Pressure

    HRSD, the regional wastewater treatment utility in southeast Virginia, had been experiencing high pressures in their Williamsburg area force main network during wet weather events.

  • Updating Consumer Perceptions On The Value Of Water

    Here are some links and guidelines designed to help utilities change their perspective on water as a low-cost resource of virtually unlimited supply. 

  • Long-Term Cost Of Pump Oversizing

    Pump oversizing drives hidden costs through energy waste, reduced reliability, and increased wear, making proper sizing and modern controls critical for long-term efficiency and performance.

  • Six-Effect Black Liquor Evaporation System

    The pulp mill at Veracel Celulose was commissioned in mid-2005. The HPD® black liquor evaporation system, designed by Veolia Water Technologies and installed by Confab Equipamentos S.A., was considered successful at start up.

  • Retrofitting: Is It Right For Your Sewage Lift Station?

    It’s just past 10:00 on a Friday night, and the phones start ringing in the pockets of the on-call collection systems operators. It’s an alarm for another pump clog at one of your sewage lift stations — the second one this week.

  • EZ VALVE Keeps Multi-Million-Pound Sellafield Project On Track

    The AVT EZ Valve provided an efficient solution at the Sellafield Nuclear Site in Europe, saving valuable time and keeping a multi-million-pound project moving on schedule.

  • Stay Grounded: Avoiding Mag Meter Mishaps

    Electromagnetic (mag) meters are a desirable metering choice for their incredible accuracy and low to no maintenance required over its lifespan. Operating with no moving parts, the appeal is high – however, the ability to troubleshoot in-field is challenging and time-consuming. Luckily, there’s a major contributing factor in installing an effective mag meter that can set you (and your operations) up for success: grounding.

WASTEWATER APPLICATION NOTES

  • Reduce SBR Maintenance Costs With Jet Aeration

    Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

  • Harmonics Reduction Methods

    There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

  • Mapping And Identifying The Source Of Water Quality Issues

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  • 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.

  • Bringing Efficiency And New Confidence To BOD₅ Analysis

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

  • 'TOTEX' Is Key When Purchasing Instrumentation

    There’s a lot to be considered in the price tag of an ultrasonic instrument. Derek Moore from Siemens explains how the historical way of thinking only of capital costs needs to change to the more holistic approach of total expenditures.

  • UV Technology Offers Solution For Emerging Water Crisis

    Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

  • Complete Flow Solutions

    Siemens’ extensive portfolio includes various flow measurement technologies, such as Coriolis, clamp-on ultrasonic, vortex, and differential pressure meters, catering to a wide range of industrial needs.

LATEST INSIGHTS ON WASTEWATER

  • A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.
  • Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
  • Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
  • Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.

  • 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.
