WASTEWATER CASE STUDIES AND WHITEPAPERS

  • White Paper: Challenging Urban BMP Assumptions There are two broad classifications of structural Best Management Practices (BMPs). This paper is concerned with devices or techniques that are intended to capture and hold materials that can be separated by gravity, buoyancy, screening, and skimming. By John Moll, CEO, CrystalStream Technologies

  • Do More With Less: Integrating Nutrient Removal Control Improves Treatment Capacity And Efficiency

    Wastewater treatment plants (WWTP) are facing many challenges. Permits on nitrogen and phosphorus in the effluent water are progressively becoming stricter in order to protect surface waters from eutrophication. At the same time, plants are required to reduce both energy and chemical consumption and are often challenged with limited time and staff. In total, they are required to do more with less. In order to meet these challenges, a plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system – the OSCAR process performance optimizer with NURO controller.

  • Bench Test Instructions For Your Case Study

    Natura Solve provides a complex liquid medium that is produced via a proprietary fermentation process. It consists of a selected spectrum of naturally occurring microorganisms, sustained within a matrix of micro elements and macro elements that provide the critical building blocks for respiration and growth. Thus it simultaneously works as both a biocatalyst, stimulating endogenous bacteria metabolic and production rate and a specialized delivery medium for the highly effective bacteria. The formula is very aggressive due to the essential balance between the selected groups of microorganisms, which, when combined with the enzymes they produce, synergistically create catalyzing proteins that significantly speed up the biochemical reactions and natural decomposition processes of the organic material into humic matter.

  • UV Treatment Upgrades In Wales

    In order to improve the treatment performance (because of the continued cost to maintain compliance), and ensure that it would eventually have the treatment capacity to meet future population growth equivalent of up to 225,000, Swansea WwTW was in need of an equipment upgrade.

WASTEWATER APPLICATION NOTES

  • A Non-Intrusive Solution For Measuring Wastewater Flow In A WWTP's Iron Pipes

    A municipal association needed to understand if wastewater was being equally distributed across two cast iron pipes within its wastewater treatment plant. Learn how clamp-on ultrasonic measurement helped successfully measure the flow.  

  • Why Measuring Hydrogen Sulfide In Wastewater Matters

    Hydrogen sulfide (H2S) gas in wastewater environments is a familiar concern. But waiting until its odor is detected can be too late to exert as much control over it as desired. Fortunately, a new ability to monitor H2S concentrations — in the liquid wastewater stream, in real time — is advantageous for wastewater professionals in terms of safety, cost, and consumer complaints. Here are four ways to capitalize on that capability.

  • Sewage Lift Station Pumping System

    Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

  • Removal Of PFCs With Activated Carbon

    In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

LATEST INSIGHTS ON WASTEWATER

  • 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.
  • 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.
  • Emerging state water reuse regulations are driving adoption of ozone and advanced oxidation, requiring flexible, high-performance systems to meet pathogen, trace organic, and DBP control objectives.
