Drinking Water Application Notes

  1. Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications

    Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

  2. Hach FilterTrak 660™ Sc Laser Nephelometer Even More Practical For Ultra-Low Turbidity Monitoring

    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.

  3. Application Note: YSI Water Quality Monitoring Buoys Help Connecticut DOT Protect The Housatonic River
    When replacement of the Sikorski Bridge spanning the Housatonic River was authorized, Paul Corrente and the Connecticut Department of Transportation (CT-DOT) set about the design and development of a water quality monitoring program to monitor the contractor’s in-water activities to insure full protection of the river from perturbation
  4. Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives

    Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.

  5. 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.

  6. Disinfection In Drinking Water: Choosing The Right Chlorine Analyzer For Your Application

    Disinfection is a very important part of the drinking water treatment process, and choosing between an amperometric and colorimetric chlorine analyser is a decision that depends on a variety of factors. Below you will find out why a colorimetric analyser was the right choice for our customer, given their specific situation.

  7. 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.

  9. Monitoring Aromatic Organics For Optimizing Coagulation

    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.

  10. 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.
