Wastewater Treatment Application Notes

  1. Disinfection And Emerging Contaminant Removal With HyDOZ®
    3/20/2014

    In the summer of 2012, BlueInGreen partnered with a facility in Arkansas to study disinfection of wastewater and removal of emerging contaminants of concern (ECC) by utilizing dissolved ozone. The plant has a firm capacity of 12 MGD and includes primary clarification, activated sludge, secondary clarification, and sand filtration prior to the existing UV system.

  2. Disinfection By-Products (DBP) Precursor Monitoring
    2/1/2013

    Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.

  3. 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.

  4. Improving Compliance Through Real-Time Phosphorus Control
    4/18/2017

    Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

  5. Precise Control Of Dissolved O2 And N2 In Semiconductor Applications Using 3M Liqui-Cel Membrane Contactors
    7/12/2017

    Semiconductor manufacturers increasingly want precise control of O2 and N2 concentrations in ultrapure water. Specifically, the polishing loop of a semiconductor plant needs to control dissolved O2 to low levels of 1 ppb or 5 ppb while simultaneously controlling the dissolved N2 between 8–12 ppm.

  6. Mapping And Identifying The Source Of Water Quality Issues
    6/28/2017

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  7. 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.

  8. Bringing Efficiency And New Confidence To BOD5 Analysis

  9. Dissolved Oxygen Measurement In Wastewater Treatment
    11/11/2013

    A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

  10. Application Note: Dairy Farms Use YSI Instruments To Map Volume Of Wastewater Lagoons
