  • White Paper: Passive Filter - Sustainable BMP For Permanent Stormwater Treatment Of Heavy Metals, Nutrients, Hydrocarbons And Sediment
    White Paper: Passive Filter - Sustainable BMP For Permanent Stormwater Treatment Of Heavy Metals, Nutrients, Hydrocarbons And Sediment Passive filtration provides a sustainable alternative to classical drainage concepts for source control of hydrocarbons, heavy metals, and nutrients that endanger our water bodies. In urban areas with high building density, traditional drainage concepts like wetlands are not available and the concept of decentralized treatment facilities that can be housed in catch basin structures are a viable option for treatment of pollutants.

  • Duperon Expands Solids Handling Product Line With Washer Compactor Discharge Extension Option
    Duperon Expands Solids Handling Product Line With Washer Compactor Discharge Extension Option

    Since the beginning, Duperon has collaborated with customers to provide customized solutions for site-specific applications. Our most recent development to follow in this tradition transports debris up to 40 feet directly from the discharge of the washer compactor. The Duperon Washer Compactor Discharge Extension Option entered development when we heard several customers describe the difficulty of conveying screenings. While their applications varied — some required vertical conveyance, some had a limited footprint for operations, some had had enough of the frequent jams of their vertical conveyors and some others needed a long horizontal run — their difficulties with current solutions were shared.

  • Improving Total Nitrogen Removal
    Improving Total Nitrogen Removal

    To protect the sensitive waters of the Neuse River Basin, the State of North Carolina formally adopted a nutrient management strategy in 1997 which established Total Maximum Daily Loads for all point source contributors of Total Nitrogen (TN) to the Neuse River. By upgrading its oxidation ditches, this Eastern NC plant saw a reduction of 76% TN compared to its average discharge from the past 6 years.

The process uses ion exchange resin to remove the ions from the feed stream, producing pure water.

  • Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
    Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency

    One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.

    Total Kjeldahl Nitrogen: Simplified With s-TKN™

    The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.

    I have been in the waste treatment business for some years now, and I am continually surprised with what I see promulgated by the people that do this every day and should know better. Out West (Texas, actually), we see life as a more or less continual struggle with all kinds of adversaries. Collectively we call them varmints, and they are ever present as we go about our daily duties. There is much to be learned from folklore in establishing a common-sense perspective, and the convergence of Texan culture and waste treatment technology (and even water treatment) are cases in point.
