WASTEWATER FEATURES, INSIGHTS AND ANALYSIS

  • Water Resource Recovery Facility Replaces its Aging UV System - Murfreesboro, Tennessee (Case Study)
    Water Resource Recovery Facility Replaces its Aging UV System - Murfreesboro, Tennessee (Case Study)

    Significant innovation had occurred in the 17 years since the TrojanUV4000™ was installed at the Murfreesboro Water Resource Recovery Facility. Advancements associated with system efficacy, simplified maintenance, and energy efficiency had been introduced, all of which correlate to cost savings. Such advancements can all be found in the TrojanUVSigna™ – the UV system that was selected for the upgrade.

    Jet aeration systems are extremely efficient due to their high alpha factor and clean water oxygen transfer performance. Proper start-up, operation, and maintenance will ensure reliable service and a long life.

  • BIOSTYR® Improves Health Of The Long Island Sound
    BIOSTYR® Improves Health Of The Long Island Sound

    The New Rochelle Wastewater Treatment Plant is located in the Westchester County, New York, discharging to the Long Island Sound. It serves a population base of 65,000 people and is permitted to treat average flows of up to 20.6 MGD. Operating with primary clarification and pure oxygen-based activated sludge treatment since a 1979 upgrade, the plant only removed BOD and TSS from the wastewater.

  • Energy Savings With Jet Aeration: The Devil Is In The Details
    Energy Savings With Jet Aeration: The Devil Is In The Details

    Conserving energy and saving costs are always on the minds of wastewater professionals. Aeration accounts for more than 50 percent of electrical usage at most treatment plants. Improved aeration efficiency will always work toward the goals of saving energy and reducing operating costs.

  • How To Boost Industrial Plant Capacity By Retrofitting Aeration Tanks
    How To Boost Industrial Plant Capacity By Retrofitting Aeration Tanks

    As industries expand, they typically need to increase the capacity of their wastewater treatment facilities. Increasingly stringent regulatory requirements, such as lower nitrogen limits, may also signal the need to boost treatment capacity. Installing additional tanks and larger equipment not only adds capital costs but increases operating costs as well.

  • Bringing An END™ To RO Brine And Difficult Brackish Water Treatment
    Bringing An END™ To RO Brine And Difficult Brackish Water Treatment

    Access to clean, safe, fresh water is one of the greatest challenges facing humanity in the 21st century. By some estimates over 1.5 billion people face water scarcity issues that directly threaten their health or economic welfare on a daily basis. More concerning, the impacts of climate change and global population growth are expected to exacerbate these issues to impact over 2.3 billion people by the year 2050. These sobering facts are why six of the United Nations (UN) Sustainable Development Goals (SDGs) are focused on providing access to clean, safe water. Part of solving this challenge is reducing industrial water consumption to conserve water resources.

  • Aqua Caiman Articulating Rake Screen

    The Aqua Caiman™ represents the next generation of multi-rake mechanical bar screens. In designing the screen, Parkson combined over 40 years of experience working on thousands of in-channel screen installations with in-depth market and engineering research. This allowed us to better understand the weaknesses of existing multi-rake and articulating rake screens.

  • Water Treatment Analytics: A Road Map To Greater Efficiency
    Water Treatment Analytics: A Road Map To Greater Efficiency

    From the largest metropolitan water treatment plant (WTP) or wastewater treatment plant (WWTP) operations to the smallest rural systems, the goals are essentially the same — achieve regulatory compliance and the most efficient results at the lowest practical cost. The most feasible (i.e., affordable) control solutions vary by process, plant size, and budgetary limitations. Here are several high-level guidelines to achieving a common strategy that works across virtually all applications: good data, properly analyzed, yields good results.

  • All-Natural Biofilm Media Derived From Plant Stock Enhances Clarifier Settling
    All-Natural Biofilm Media Derived From Plant Stock Enhances Clarifier Settling

    When clarifiers are not settling like they should, problems arise, including reduced capacities, high sludge volume indexes (SVI) and sludge blanket levels, and infiltration/inflow (I/I) washout issues.

The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.

  • Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency
    Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency

    California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.

    Is Cryptocurrency Going Down the Drain?

    Talk about making waves. Cryptocurrency — digital “tokens” or “coins” rooted in computer code and valued for the very fact that they are disconnected from governments and banks — have experienced spectacular rises and falls in recent months. The crypto-economy is already worth hundreds of billions of dollars (REAL dollars!), and it’s anyone’s guess how fast it will grow after that.
