Wastewater Treatment Application Notes

  1. Monitoring Nitrates In Drinking Water And Wastewater

    Nitrate is present in high levels in wastewater due in part to the high nitrates present in human sewage but also from some types of industrial effluent entering the municipal sewer system.

  2. Application Note: Preliminary Performance Study On An On-Line TOC Analyzer In Pharmaceutical Applications
    5/28/2009
    Total Organic Carbon (TOC) analysis is an effective technique for detecting and measuring the presence of organic contaminants in waters used throughout industrial processes, municipal water uses, and for determining residual concentrations of organic material on the surfaces of equipment used in the manufacture of active pharmaceutical ingredients.

  3. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Municipal Wastewater
    2/7/2014

    This application note presents comparative data obtained on influent and effluent wastewater samples using laboratory and on-line TOC analyzers employing the heated sodium persulfate oxidation technique in USEPA-approved methods 415.3 and SM 5310C.

  4. DR6000 In The Brewing Industry
    4/18/2017

    Compliance and consistent high quality are two of the key goals within the beverage industry. Hach® provides support for these goals through comprehensive analyses of water and beer.

  5. Thermal Flow Meters For Mixed Gas Applications
    5/22/2017

    Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.

  6. Increase Ink Jet Print Speeds By 15% With 3M™ Liqui-Cel™ SP Series Membrane Contactors
    6/30/2017

    Many high-speed, wide-format ink jet printer manufacturers are now using 3M™ Liqui-Cel™ SP Series Membrane Contactors to remove air bubbles and excess gases from ink to reduce downtime and improve yields. Entrained bubbles and excess gases are often the cause of printing surface defects and ink flow interruptions that can cause printer shut-downs.

  7. Importance Of Measuring UV Transmittance (UVT) For UV Disinfection
    2/1/2013

    UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm.

  8. Orion DUAL STAR™ Quick Start Note - Nitrate In Water & Wastewater
    7/31/2009
    The Thermo Scientific Orion DUAL STAR meter shows the results of both input channels simultaneously.
  9. 3M™ Liqui-Cel™ Membrane Contactor Technology Being Evaluated For Dissolved Gas Removal From Water In Many Hydrocarbon Processes
    6/28/2017

    The oil and gas industry has utilized various deaeration technologies for many years to remove dissolved gases, particularly oxygen, from injection water. In many hydrocarbon recovery and water processes, degassing is necessary in order to minimize environmental impact, improve operating efficiency, avoid process issues and help protect system components.

  10. Reduce SBR Maintenance Costs With Jet Aeration
    6/16/2017

    Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.
