Flow-based DO control and advanced blowers help stabilize aeration, reduce energy consumption, and improve treatment performance, turning a major wastewater cost center into an efficiency opportunity.

WASTEWATER CASE STUDIES AND WHITEPAPERS

WASTEWATER APPLICATION NOTES

  • Flow Monitoring In The Partially Filled Discharge Of A Rainwater Retention Basin

    Read about managing water discharge into a mixed water drainage system, electromagnetic flow measurement of water loads, and automated discharge control by way of a structure with overflow. 

  • Scrubber Application

    This customer supplies district heating and electricity for the region of Sønderborg. For one of their waste applications a MAG meter failed within 6 months, and was successfully replaced with a Panametrics Aquatrans AT600.

  • Improving Compliance Through Real-Time Phosphorus Control

    Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

  • 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.

  • Nitrogen-Reduction Treatment Systems For Long-Term Operations

    The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

  • Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

  • Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing

    With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

  • Chlorine Measurement In Wastewater And Regulated Discharge Requirements

    Homes, industry, schools, and businesses all generate sanitary waste, or sewage. Sewage treatment is a multistage process that cleans up wastewater before discharge or reuse. In the final step of the treatment, disinfectants are added to kill disease-causing organisms. Common disinfectants are chlorine gas and sodium hypochlorite. Chlorine dosage levels are designed to leave almost no residual in the wastewater after treatment

  • 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).

  • Microbial Control In Cheese Making

    Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

De Nora offers reliable, robust and proven ozone solutions to ensure peace of mind, backed by extensive global experience.

Is your industrial facility close to the benchmarks?  Do you want an added measure of certainty to be in compliance with your industrial general stormwater permit?  Is your industrial facility unpaved or does it have broken pavement that is affecting your stormwater quality?  Does your permit require corrective actions?  Or is the facility large and you’d like to incorporate end-of-pipe stormwater treatment that doesn’t break the bank?  

OMNIPURE™ is the only marine sewage system that oxidizes sewage in an electrochemical cell as well as generates sodium hypochlorite for the disinfection of the sewage streams. It offers effective electrolytic treatment of both black and gray water through a patented and certified process. OMNIPURE systems range in treatment capacities from 781 to 15,842 gal/ day, while utilizing small installation floor space.

Grittec is a grit classifier that separates rock, sand, and grit from screened wastewater. A large surface tank allows screened material to settle to the bottom, where a shaftless screw conveys screened debris to a dumpster.

Simplify water analysis with a new class of spectrophotometers.

TurboCoag is an innovative Tesla pump with patented rotating electrodes. These electrodes are energized with an electrical potential that causes current to flow through the fluid to be treated, dissolving the anodes into reactive anions into the water which binds to the contaminants, forming a strong floc. 

LATEST INSIGHTS ON WASTEWATER

  • 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.
  • 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.
