  • Cost Effective Sour Water Stripping
    Cost Effective Sour Water Stripping

    Refineries are challenged to properly reuse or dispose of sour water by removing ammonia (NH3) and hydrogen sulfide (H2S) from water through a process called stripping.

  • Not All UV Lamps Are Created Equal
    Not All UV Lamps Are Created Equal

    When the Summerville, GA, WWTP was looking to convert from chemical disinfection to UV, staff made the common mistake of purchasing low-price aftermarket lamps to keep costs down. Within eight months, the lamps in the UV system failed to meet expectations for permit requirements, and they had to gain approval for emergency procurement of WEDECO’S ECORAY® lamps as replacements. Today, the plant achieves the required disinfection with a significant reduction in energy use.

  • Hybrid Blowers: Should WWTPs Believe The Hype?
    Hybrid Blowers: Should WWTPs Believe The Hype?

    In 2010, an energy analysis of the Freeport Wastewater Treatment Facility in southern Maine revealed that the plant had significant inefficiencies in usage. Specifically, the plant’s 30-year-old multistage centrifugal aeration blowers were accounting for as much as 90 percent of electricity consumption.

  • Intelligent Data From Water Meters
    Intelligent Data From Water Meters

    Utilities can now use intelligent data to improve customer service, increase revenue, and expand conservation initiatives. Neptune’s N_SIGHT™ software suite includes cloud-based intelligent data hosting and analytics management. This video shows how the software can reduce non-revenue water, eliminate major investments in internal IT support, and reduce truck rolls with virtual disconnects.

  • On-Site Chlorine Generation Solves Problems For MUA

    By making a fresh, dilute hypochlorite solution only as needed, Authority eliminates numerous maintenance and reliability issues.

  • Raw Water Treatment For Drinking Water Production
    Raw Water Treatment For Drinking Water Production

    Water is an essential element of life: it accounts for 70% to 80% of the weight of a human being. The quality of water is an important parameter that affects all aspects of the well-being of ecosystems and mankind, from human health, to food production, economic activities and biodiversity.

The result: higher oxygen-transfer efficiency and reduced power costs to operate the system.

  • Send In The Bugs: Biological Filtration Solves Contaminant, Capacity Concerns
    Send In The Bugs: Biological Filtration Solves Contaminant, Capacity Concerns

    Every drinking water system is part of the community it serves, but not quite like Waterford Township, MI, where treatment plants sit side-by-side with homes. The unique, decentralized system utilizes 13 separate treatment plants to clean the local, iron-rich well water. Due to “explosive growth,” the municipality needed to bolster the water supply with more wells, but had zero room for plant expansion. How do you treat more water in the same space?
