  • A More Cost-Effective Measurement Solution For Open-Channel Flow
    A More Cost-Effective Measurement Solution For Open-Channel Flow

    Open channels are an efficient way to feed wastewater treatment facilities but pose a challenge because the flow rate can be difficult to measure with traditional devices. Until recently, radar level measurement devices have been cost-prohibitive for most municipalities. Newer advancements, however, have brought the cost down significantly, so it is now feasible for wastewater plant managers to consider adopting the technology for open-channel applications.

    Article: A Battle Cry For The Nutrient Warriors

    In July 2009, a group of more than 70 leading nutrient removal experts gathered at the Blue Plains Advanced Wastewater Treatment Plant in Washington, DC. The Water Environment Research Foundation (WERF) brought the group together for a workshop to assess the status of our battle to keep excessive nutrient levels from claiming the health of our natural water resources. This gathering of "nutrient warriors" couldn't have come at a better time. Landmark nutrient management activities are already underway.

  • Contact Lens Becomes Latest Pollutant In Wastewater

    The latest disposable causing a stir in the wastewater treatment world is the contact lens. Researchers from Arizona State University recently presented their findings at an American Chemical Society event showing that contact lenses flushed down the toilet or washed down the drain can pass through wastewater treatment plants and accumulate in sewage sludge. As sludge is often applied on land for disposal and fertilizing, macro- and microplastics from lenses enter terrestrial ecosystems.

  • Dissolved Oxygen Measurement
    Dissolved Oxygen Measurement

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  • Pile Cloth Media Filtration For Clean Utilities
    Pile Cloth Media Filtration For Clean Utilities

    Cooling towers and boilers consume the most fresh water in the industry, with industrial process waters carrying the balance. Power plants and refineries use more water volume for the cooling process than any other area of the facility. Mining and food and beverage industries consume higher volumes for their processes. Clean water may come from a range of sources, including clarified surface waters, groundwater or properly treated wastewater (reuse) sources.

    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.

    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.

  • All WirelessHART Devices Are Not Created Equal
    All WirelessHART Devices Are Not Created Equal

    Though they all must support routing functionality, some devices do it better than others.

    Routing consumes more energy, so the lifetime of the battery will be affected.  Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.

    The Importance Of Measuring Total Organic Carbon

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

    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.
