Drinking Water Application Notes

  1. A Strategy For Optimizing Water Treatment Plant Performance Using Light Scatter Technologies

    Two new particle detecting technologies have been developed to help optimize filter performance at water treatment plants (WTP).

  2. Application Note: Vertical Profiling Safeguards Drinking Water And Sheds Light On Cyanobacteria
    A search for algal toxins in North Carolina reservoirs has evolved into an ongoing early warning system for three important drinking water reservoirs—which serve two large cities—and yielded a greater understanding of the dynamics of blue-green algae, or cyanobacteria, in the state’s reservoir system.

  3. The Basics: Testing RO Quality

    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.

  4. Waste Technologies Transform Problems To Profit

    Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

  5. Control Of Active Chlorine Disinfection By-Products (DBPs) Of Drinking Water Using The THM Plus Method

    Determining trihalomethane levels using standard analytical methods requires expensive equipment and highly qualified personnel, which also means that analysis costs are very high. For these reasons, trihalomethane analysis poses a serious problem for companies that supply drinking water. Read the full application note to learn how two drinking water laboratories improved quality control of water delivered to end users.

  6. Accurate Flowmetering For Enhanced Water Network Performance

    Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gaining an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas including supply planning, maintenance and resource deployment, leakage detection and rectification and the overall environment, in terms of controlling abstraction and reducing unnecessary draw on natural resources.

  7. Bottled Water Industry: Liquid Analytical Solutions

    Americans consume more than 9.1 billion gallons of bottled water annually - an average of twenty nine gallons per person every year. 

  8. Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples
    Total bound nitrogen (TNb) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TNb measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters.

  9. The Basics: Keeping Our Water Clean Requires Monitoring

    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.

  10. Leak Detection Using Conductivity

    Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers,or jacketed vessels. Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.
