Drinking Water Application Notes

  1. Control Of Drinking Water Clarifiers

    "The variable concentration of solids when purging lamella clarifiers creates problems with sludge dewatering. These problems are exacerbated when changing the flocculant. Read the full application note to learn how automatic control of purge cycles for clarifiers using the Sonatax sludge level probe resulted in reduced energy consumption and maintenance at the plant."

  2. Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE)

    Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

  3. Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.

  4. Operations And LRV Calculations At Southwest Pipeline Project Drinking Water Treatment Facility

    This presentation will discuss the operation of a 4 MGD pressurized two-stage Ultrafiltration (UF) plant over a 14 month period at the Oliver-Mercer-North Dunn (OMND) Drinking Water Treatment Facility, North Dakota.

  5. Ultrasonic Level Measurement In Water And Wastewater Plants

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

  6. Advances In Paper-Based Devices For Water Quality Analysis

    Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

  7. Application Note: Turbidity Monitoring In Drinking Water Treatment Plants

    Turbidity, or the relative clarity of a liquid (in this case drinking water), is caused by the presence of microscopic particles such as clay, silt, or other fine undissolved matter

  8. 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.

  9. Water Determination In Liquefied Petroleum Gas Using GC BID And Ionic Liquid Column Watercol™

    Water in petrochemical feedstocks can cause problems for processors. Freezing of pipe lines and valves and poisoning of expensive catalysts are just a few examples.

  10. Cloth Media Filtration Removes Coal Ash And Coal Fines At Power Plants

    Coal-fired power plants generate coal fines and coal ash from a number of sources, including coal combustion residuals (CCR), particularly fly and bottom ash from coal furnaces, and coal pile runoff during rain events. In support of an industry-wide effort to reduce, improve, and remove coal ash ponds, a variety of technologies have been tested and employed. Read the full application note to learn more.
