Wastewater Treatment Application Notes

  1. Degassing Sea Water Has Never Been This Compact, Efficient, And Adaptable
    6/27/2017

    3M™ Liqui-Cel™ Membrane Contactors offer a modular skid option for off-shore oil platforms that is significantly smaller and lighter than traditional vacuum towers.

  2. WWTP Utilizes Online Instrumentation And SCADA To Keep Operating Costs Low And Effluent Quality High
    2/6/2013

    Providing the best value to wastewater customers requires a team of operators that have a deep sense of ownership and are committed to continuous improvement. Such is the case for the operating staff at one wastewater treatment plant whose progressive attitude and a philosophy of “do it right” led them to an investment in online instrumentation and SCADA for compliance, monitoring, and control.

  5. All WirelessHART Devices Are Not Created Equal
    12/4/2015

    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.

  6. 3M™ Liqui-Cel™ Membrane Contactors Are Widely Used In The Soft Drink And Brewing Industries To Control Dissolved Gasses
    7/10/2017

    Gas control is an important concern in the beverage industry. Oxygen in the water can oxidize flavor components and shorten the shelf life of the product. Carbon dioxide can also have an impact on taste and pH of the product.

  7. Harmonics Reduction Methods
    4/17/2017

    There are several basic methods for reducing harmonic voltage and current distortion from nonlinear distribution loads such as adjustable frequency drives (AFDs). Following is a description of each method, along with each method’s advantages and disadvantages.

  8. Aerated Biological Nitrogen Removal
    7/16/2013

    Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

  9. Application Bulletin: Reverse Osmosis
    3/19/2008
    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached
  10. Ultrasonic Level Measurement In Water And Wastewater Plants
    5/19/2016

    Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
