Clean Water Disinfection APPLICATION NOTES

  1. Disinfection In Drinking Water: Choosing The Right Chlorine Analyzer For Your Application
    4/13/2017

    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.

  2. Control Of Active Chlorine Disinfection By-Products (DBPs) Of Drinking Water Using The THM Plus Method
    4/13/2017

    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.

  3. Application Note: Ozone Measurement In Potable Water
    3/1/2010

    Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.

  4. Flow Meter Enhances Chlorination System Performance For Municipal Water Department
    12/12/2017

    The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.

  5. Benefits Of UV Transmittance (UVT) Field Testing For Selling & Servicing UV Disinfection Systems
    2/1/2013

    The Real UV254 'P' series portable meters can be used to measure UV transmittance (UVT) in a number of situations, and are especially beneficially when working with small UV disinfection systems. The following cases outline two situations in which Real Tech's portable meters are invaluable.

  6. 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.
  7. Comparison of UV vs. Sodium Hypochlorite (Fact Sheet)
    11/23/2011

    Hypochlorite has some significant environmental concerns associated with DBPs and residual toxicity.

  8. Removal Of Chloramines With Activated Carbon
    12/30/2013

    In order to reduce the formation of harmful disinfection byproducts in drinking water, alternative disinfectant use has become increasingly widespread. Monochloramine is a leading alternative disinfectant that offers advantages for municipal water. This tech brief details the removal of monochloramine using activated carbon.

  9. Control Of Drinking Water Clarifiers
    4/13/2017

    "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."

  10. Chlorine Method For UKAS Accreditation And DWI Compliance At Welsh Water
    4/13/2017

    In 2013 the Drinking Water Inspectorate for England & Wales announced that water samples collected in England and Wales must be tested in a laboratory that meets specific standards for drinking water sampling and analysis. At the time of the new instruction, the chlorine method employed at the Welsh Water Bretton laboratory was unable to meet these requirements, notably for the prescribed limit of detection. This prompted the laboratory to investigate new analytical options for monitoring residual chlorine.
