Drinking Water Measurement Application Notes

  1. 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.

  2. 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).

  3. Water Distribution System Security Monitoring
    2/5/2013

    Ensuring safe drinking water doesn’t end when the water leaves the water treatment plant. Protecting the safety and security of drinking water from accidental or intentional contamination within the distribution system is becoming increasingly important.

  4. Bringing Efficiency And New Confidence To BOD₅ Analysis
    2/4/2013

    Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.

  5. Disinfection By-Products (DBP) Precursor Monitoring
    2/1/2013

    Chlorine has long been used as a primary disinfection method for many water and wastewater treatment applications. However, there is growing concern about the harmful DBP’s produced by the use of chlorine.

  6. Monitoring Aromatic Organics For Optimizing Coagulation
    2/1/2013

    With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.

  7. Organics Monitoring (TOC)
    2/1/2013

    Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small.

  8. Phosphate Corrosion Control In Drinking Water
    11/21/2012

    Corrosion occurs because metals tend to oxidize when they come in contact with oxygenated water, resulting in the formation of stable metal oxides.

  9. Preliminary Assessment Of Water Quality In Riviera Grise Near Port-Au-Prince, Haiti
    10/17/2012

    The Riviera Grise drains water from the Cul-de-Sac watershed, Haiti, which covers most of the rural areas along the flood plains and areas that extend into steep hillsides. It also covers urban areas of Port-Au-Prince, the capital city of Haiti.

  10. Measuring The Chlorine Content In The Emergency Chlorination Of Waterworks
    12/14/2011

    Many municipal waterworks perform no permanent disinfection of drinking water. However, in many cases a process known as emergency chlorination takes place. The process is switched on in case of need, adding chlorine to the drinking water as a disinfectant.
