Wastewater Treatment Application Notes

  1. Orion DUAL STAR™ Quick Start Note - Nitrate In Water & Wastewater
    The Thermo Scientific Orion DUAL STAR meter shows the results of both input channels simultaneously.
  2. Removal Of PFCs With Activated Carbon

    In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

  3. Improved Efficiencies In TOC Wastewater Analysis For Standard Method 5310B And EPA Method 415
    Total organic carbon (TOC) measurement is of vital importance to the operation of water treatment due to organic compounds comprising a large group of water pollutants. TOC has been around for many years, and although it is a relatively simple analysis in theory, operational efficiency is paramount.
  4. Determination Of Polycyclic Aromatic Hydrocarbons In Seafood

    Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.

  5. Degassing Sea Water Has Never Been This Compact, Efficient, And Adaptable

    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.

  6. Microbial Control In Cheese Making

    Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.

  7. Ion Exchange Resins Reduce Pollution From Refineries

    A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

  8. Wireless Lift Station Monitoring Application Note

    Lift stations are remote pumping facilities that move wastewater from lower to higher elevation. Monitoring lift stations is important to collection system operators.

  9. 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.

  10. 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.
