WASTEWATER FEATURES, INSIGHTS AND ANALYSIS

  • Location, Location — The Key To Aeration
    Location, Location — The Key To Aeration

    As with any industrial process, the right tool for the job depends on the nature of the task at hand. In aerobic wastewater treatment, that optimal choice often comes down to a balance between the biological and financial demands of the application. Either way, here are several performance comparisons of how multiple aeration methods and locations stack up in industrial wastewater treatment applications.

  • A Lid For Every Pot: Retrofitting To Meet New Aeration Challenges
    A Lid For Every Pot: Retrofitting To Meet New Aeration Challenges

    Aeration for industrial and municipal wastewater treatment involves more than simply moving volumes of air through a treatment basin. It really comes down to creating and sustaining an optimal oxygenated environment for microorganisms to convert oxygen consuming compounds into CO2 and water. Here are some key considerations for making better retrofit decisions about upgrading existing basin capacity and efficiency with jet aeration.

  • Are Your Pumps Running As Efficiently As Practical?
    Are Your Pumps Running As Efficiently As Practical?

    In water and wastewater operations, optimizing energy use plays a huge role in cost efficiency, but how can you know if pumping equipment and other motors are running as efficiently as possible? Analytics systems that interpret performance from a variety of data points — pump curves, run time, flow rates, vibration, temperature, energy consumption, etc. — can quantify pump operation to keep performance efficiency on an upward track.

  • Aeration Considerations: What To Know Before You Buy
    Aeration Considerations: What To Know Before You Buy

    Unlike most municipal wastewater treatment plant (WWTP) applications, industrial wastewater can vary widely from one application to another, even within the same plant, depending on the process being run. Industrial wastewater professionals — especially those facing specific challenges or planned volume increases — can benefit from comparing key points of differentiation in jet aeration system options before making any upgrade.

  • Coral Reefs Provide Flood Protection Worth $1.8 Billion Every Year — It’s Time To Protect Them
    Coral Reefs Provide Flood Protection Worth $1.8 Billion Every Year — It’s Time To Protect Them

    The biggest obstacle to investing in natural infrastructure, such as wetlands and reefs, often is that experts have not figured out how to value the protection that these habitats provide in economic terms. But a new report, published by the U.S. Geological Survey’s Coastal Hazards Program, solves that problem for one of our planet’s most biodiverse ecosystems: coral reefs.

  • Translating Aeration Efficiency Into Dollars
    Translating Aeration Efficiency Into Dollars

    The hardest aspects of comparing efficiencies among submerged aeration technologies are the many variables in capital expense (CAPEX), operating expense (OPEX), and complexity of wastewater makeup. Instead, consider comparing the physics of different aeration technologies and the relative costs associated with them. Here are five major categories for evaluating industrial wastewater aeration efficiency.

  • Avoiding The Low-Pressure Trap Of Air Release Valves
    Avoiding The Low-Pressure Trap Of Air Release Valves

    Air release valves play a critical role in maintaining pipeline integrity, but most don’t seal properly at lower pressures without changing to a softer seat, when the system is most at risk. The key to avoiding problems, while achieving optimal performance, is selecting air release valves that work in low- and high-pressure applications. The good news is that there are some advanced valve products on the market that seal over a much wider range.

  • How To Predict And Prevent CSOs And SSOs
    How To Predict And Prevent CSOs And SSOs

    Combined and sanitary sewer overflows are natural hazards for wastewater collection systems. Without a comprehensive solution to monitor troublesome conditions, overflows can be triggered with little warning and lead to expensive and embarrassing situations. Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.

  • Cooling Towers Are Not The Problem — Or At Least They Don’t Have To Be
    Cooling Towers Are Not The Problem — Or At Least They Don’t Have To Be

    Water quite literally flows through every facet of life, being the key element for everyone and everything on Earth. The world’s population is increasing at 1.1 percent (roughly 83 million) every year, an incredible and alarming rate straining the world’s fresh water supply. The increasing pressures between what humanity demands and what is currently available emphasizes the importance of conservation.

  • Growing And Flourishing In A Desert
    Growing And Flourishing In A Desert

    Water is essential to life. And it is a very precious commodity in Israel, home to 9 million people living in a rocky desert that receives about 10 inches of rain a year. By comparison, Denver, considered semi-arid, gets about 15 inches of rain a year, which is about a fourth of the precipitation a tropical city such as Miami receives.

    Wastewater Service Charges Continue To Rise

    Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying.  As you can imagine, much of the difference is to do with population size and geography.
