Drinking Water Application Notes

71. Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution
    9/29/2014

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

72. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water
    4/5/2013

    Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).

73. Defining Drinking Water Plant Backwash Profile Using The SOLITAX™ Sc Suspended Solids And Turbidity Sensor
    6/7/2013

    Today’s drinking water plants have many challenges to meet as they produce water for a fast-growing and increasingly demanding population.

74. Hach FilterTrak 660™ Sc Laser Nephelometer Even More Practical For Ultra-Low Turbidity Monitoring
    6/7/2013

    Now compatible with the Hach sc100 Controller, the FilterTrak 660 sc Nephelometer connects as a ‘plug and play’ sensor with the universal, dualchannel controller that features an inherent power supply.

75. The Basics: Keeping Our Water Clean Requires Monitoring
    4/30/2014

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

76. The Importance Of Measuring Total Organic Carbon
    4/13/2017

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

77. 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.

78. Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction
    8/4/2011
    Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day.

79. 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.

80. Protecting Pumps From Dead Head Conditions
    4/6/2017

    The C445 motor management relay offers the most configurable protection options in the industry, with features specifically designed to protect critical pumps from costly damages due to dead-head and other underloaded or starved pump conditions.
